2014 marked the 25th anniversary of Masimo. i would like to thank everyone, from our employees and customers to our investors 

and advisors, who has helped Masimo achieve its mission of improving patient outcomes and reducing cost of care by taking 

noninvasive monitoring to new sites and applications. 

We believe that Masimo Set® pulse oximetry now 

helps clinicians monitor more than 100 million 

patients a year and is the primary pulse oximetry technology

– during patient motion and low perfusion. the industry had given up and considered 

the problem “unsolvable.” clinicians were forced to live with the results – excessive 

false alarms, delayed notification due to long averaging times, inaccurate data, and 

an inability to obtain data on the most critical patients.

When Joe Kiani and mohamed diab looked at pulse oximetry signals differently 

than anyone had before, they created new possibilities. By employing advanced 

signal processing techniques – including parallel engines and adaptive filters – 

they believed they could find the true arterial signal that would allow accurate 

monitoring of arterial oxygen saturation and pulse rate, even during the most 

challenging conditions. after six years of dedicated and focused research and 

development, masimo set ® debuted in 1995 at the society for technology in 

anesthesia and won the prestigious excellence in technology Innovation award.

The Early Investors

as told by abbas Bolandgray, ron nessim 
(for Jose nessim), Harish Patel, Bobby Yazdani, 
omid Kordestani, and robert Feibusch

When Joe Kiani first proposed building an “impossible” pulse oximeter to mohamed 

diab, the idea of leaving a steady job was not too palatable to mohamed. the 

company mohamed worked for, however, was moving to colorado and mohamed 

loved southern california. so he told Joe if he could raise $75,000 he would work 

with him. Joe came up with $50,000 within two months, and mohamed gave five 

months’ notice to his employer.

they named their company vital signals, Inc.; it was founded february 1989 

when Joe Kiani had just turned 24 years old. By the summer of 1989, their first 

prototype was ready. all of this was possible due to some singularly visionary 

doctors and engineers.

abbas Bolandgray

“about a year ago, i met with Joe and thanked him for his vision, 

i bought shares, too, early on – 1990, 1991, 1992, 1993. and as

Early Advocates

as told by the late Jeremy swan, steve Barker, 
Mitchell Goldstein, Peter cox, and augusto sola

starting with a relatively small amount of financing, and no marketing department, 

the creation of masimo was a continuous uphill climb. When they invented set® – 

signal extraction Pulse oximetry technology – in 1989, they managed to separate 

the arterial signal from the non-arterial noise (e.g. venous blood movement during 

motion). this gave the company the first and only pulse oximetry technology 

scientifically and clinically proven to be accurate during challenging conditions 

of patient motion and low perfusion. Great news, but how do you sell a pulse 

oximeter in a market dominated by one company? simple – you get the thought 

leaders in medicine to review it, hoping that you can prove you’ve built a much 

better technology as promised. that approach takes courage because bad results 

from respected medical authorities can result in the demise of a fledgling company 

with limited assets. approaching the problem fearlessly, Joe Kiani and his team 

sought out tough but highly respected experts to study and test masimo products. 

speaking to the true quality of their innovative technology, masimo won the day 

and in some cases, saved precious young lives.

When masimo set® technology was first perfected, Joe, mohamed, and the team 

naturally wanted to get the technology in use for patients asaP. they calculated that 

to do that, they should license their invention to market leader nellcor or another 

company. they also discussed creating a standalone device, but other ideas came 

from the first major investors, who came to masimo by way of silicon valley. the 

route to robert feibusch, Jack lasersohn, and other venture capitalists over the years 

turned a small path into a medical technology super company. one investor wanted 

Joe and mohamed to merely create ideas and license them. others wanted to replace 

Joe as ceo – the reasoning being that almost no one was good at both innovating 

new products and running a company, too. the investors who lasted and profited the 

most, however, saw kindred spirits in Joe Kiani and mohamed diab, people who like 

themselves were willing to risk it all to make a major difference in the quality of life

Taking on the GPOs

as told by seth Bloom, sen. Herb Kohl, 
and Walt Bogdanich

By 2002, masimo was engaged in a legal battle with pulse oximetry industry 

leader nellcor. despite occasional breakthroughs like cook county Hospital in 

chicago, that the famed er tv show was about which completed a system-wide 

conversion to masimo set®, the company was in essence shut out of 95% of 

american hospitals due to the monopolistic practices of dominant companies like 

nellcor with Group Purchasing organizations who got paid by them. When nellcor 

not only manipulated GPos to keep masimo out of the u.s. hospitals, but also 

attempted to co-opt masimo technology, there was no choice but legal action. 

to break up the group purchasing organization oppression of small innovative 

companies trying to break in with better technology, government intervention 

was necessary. that came about via a senate panel chaired by sen. Herb Kohl 

of Wisconsin and sen. mike deWine of ohio, bolstered by a series of new york 

times articles, the first one tiitled “medIcIne’s mIddlemen; Questions raised  

of conflicts at 2 Hospital Buying Groups.” that piece began with the story of 

how baby Joshua diaz was saved in the hospital as a newborn due to use of a 

masimo monitor. Walt Bogdanich, the times reporter, wrote about Joe Kiani, 

“he still cannot sell his oximeter, regardless of the price, to many american 

hospitals, even though medical experts say it helps the most fragile of patients – 

premature infants.” the articles were devastating indictments of the GPo 

payoff schemes and monopolies, and after reviewing the situation and hearing 

voluminous testimony, sen. Kohl’s committee drafted legislation and persuaded 

the offending GPos to voluntarily change their ways. subsequently, masimo 

received its first contract with Premier (one of the two major GPos), and other 

med tech innovators soon found entrée to american hospitals to be much easier.

> our cruSading HeroeS: Masimo had technology that was 30 to 100 times better than 
any other pulse oximeter available, yet we could not sell it to hospitals in the U.S. due to the 
GPO monopoly. So we concentrated on small NICUs and non-GPO based hospitals, which 
were few. Then we noticed that Medical Device Manufacturers Association (MDMA), a new 
group representing medical companies, publicly said there was a problem with this whole 
GPO setup. That led us to Seth Bloom, an aide to Senator Herb Kohl, who was conducting his 
own relentless investigation.

MDMA told us we had to come to Washington to visit Sen. Kohl’s people, specifically Seth, a 
true idealist. Sen. Kohl was wealthy and didn’t need to raise money to become elected. He 
held hearings on the issue and thanks to him and Seth, we were able to sell our products in 
the U.S. and save countless lives and the eyesight of thousands of premature babies. We all 
owe Seth and Sen. Kohl copious thanks.

When we contacted 60 Minutes about our issues, they gave us Walt Bogdanich’s name. 
Walt, while previously at ABC News, broke the controversial story about tobacco companies 
manipulating nicotine to make cigarettes more addictive. Walt said the story was so big he 
was willing to go to The New York Times with it. Since a 15 minute segment wouldn’t do it 
justice, he got an agreement from them to do a whole series on the GPOs if Joe was willing 
to step up and speak up, and he certainly did. About a year and a half after Joe assisted Walt 
on his investigation, the story was shelved in the wake of 9/11, but when the story finally 
launched in March 2002, it helped change the healthcare industry for the better. 

seth Bloom

“THe group purcHaSing organizaTion iSSue and how innovative medical devices were 
being prevented from reaching patients first came to my attention at the end of December 2000. 
there was a meeting, i believe, sponsored by the Medical Device Manufacturers association. 
there was a group of maybe 10 or 15 people around the table in my office and i was in a sort of 
shock about the situation. it caught my attention in particular because it affected patient health 
and safety. i couldn’t imagine a more important competition issue. after having this meeting, 
i brought it up with Sen. Kohl, whom i worked for at the time, and who was the senior Democrat 
on the antitrust Subcommittee. i didn’t meet Joe Kiani until sometime in 2001.

“When the New york times stories on gPos appeared in 2002, we were already planning 
our hearing where Joe testified, but the first times story definitely attracted Sen. Kohl’s 
attention. He was appalled by the kinds of things the paper was writing about. the 
Senator felt the most effective use of the bully pulpit of a congressional hearing was to 
get the gPos, and their trade association, to agree to change their ways voluntarily. Joe’s 
testimony was vitally important at the first hearing.

“those testifying all told the same story – how the gPo system 
prevented crucial, in many cases potentially life-saving, 
devices from reaching patients and helped entrench the 
market positions of the large vendors.

“this hearing led to the gPos establishing codes of conduct, which 
they did only after Sen. Kohl turned the spotlight on them and 
we threatened legislation to remedy the situation. among other 
things, the leading gPos and their trade association agreed to 
end some of their worse practices – for example, ethical abuses 
and conflicts of interests where gPo executives would have 
investments in companies that obtained gPo contracts. and 
many of gPo-negotiated contracts were five to seven years. the 
gPos agreed, for clinical preference products, to limit the length 
of the contract to three years, which obviously gives competitors 
a better shot at getting in. and they agreed to end exclusive, sole 
source and bundling contracts for medical devices. Sen. Kohl was 
very directly involved in negotiating with the two largest gPos to 
get them to use these voluntary codes of conduct. it was quite an 
achievement. We had our first hearing in 2002 in the spring.

“by the summer of 2003, we had these agreements in place. 
So that was a major accomplishment of these hearings.”

sen. Herb Kohl

“i waS VerY impreSSed by Masimo and its ceo, Joe Kiani. 
in my view, Masimo was exactly the kind of company we 

wanted to encourage, an upstart company, founded by 
immigrants, taking on the industry’s incumbents with a 
better product. and this product was a basic medical device 
key to helping prevent blindness in premature babies. i was 
quite disturbed to learn that hospital gPos, acting at the 
behest of dominant suppliers, were effectively preventing 
Masimo’s devices from reaching physicians and patients. that 
patients – particularly premature babies – could be denied 
access to these critical devices was shocking to me. the 
experience of Masimo and other similarly situated medical 
device manufacturers led me to conclude that something had 
to be done to end the stranglehold on the market of the large 
incumbent suppliers resulting from the gPo system.

he needed to obtain contracts. i don’t know whether we could 
have achieved the reforms to the gPo system that we got the 
gPos to agree to without Mr. Kiani’s testimony.”

Walt Bogdanich

“i HaVe a cloSe Friend who worked in the medical device 
arena and he had complained many times about the out-
sized influence of group Purchase organizations. i always 
thought of gPos as inherently good. the story he told me 
painted a very different picture of them.

“i recall that Mitchell goldstein, a physician from a Southern 
california hospital, offered compelling testimony at our first 
hearing in 2002 about being denied access to Masimo’s 
devices, and the dangers that posed to his patients, including 
premature infants.

“our interest in the gPo system was to insure that patients 
received access to the best medical devices at the best prices. 
While we did not get involved in this issue to benefit any 
one company or group of companies – we were just acting to 
promote competition and help patients get access to needed 
medical devices – Joe Kiani’s testimony was crucial to our 
efforts. i recall how sincere he was in seeking reforms and 
how courageous he was in coming to testify. His testimony 
exposed the shortcomings of the gPo system, and yet he 
testified next to representatives of the very gPos from whom 

“i can recall with great clarity my first meeting with Joe Kiani. 
We were sitting and talking at a nice New york restaurant. For 
some reason, i remember the sun streaming in through the 
window. i had heard the outlines of Joe’s story, but i needed 
him to fill in the blanks. i also needed to assess his credibility 
in person. Needless to say, he passed with flying colors.

“the gPo story was a difficult one to tell. and, to be absolutely 
honest, our editors did not immediately see the value in spending 
a great deal of time learning about the dark side of gPos. but 
we kept at it. We followed the money and it led us to an incredibly 
important series of discoveries. the result was a compelling 
series about the hidden hand of gPos in the marketplace. 
the best part of that series – hands down – was the opening 
anecdote which dealt with Joe’s product. Without that, i’m not 
sure anyone would have read beyond the first few paragraphs.”

The Legal Warriors

as told by Joe re and steve Jensen

as 2004 began, the patent trial was on everyone’s mind, but despite advancing in 

the marketplace, masimo was $5,000,000 in debt to its law firm, Knobbe, martens, 

olson & Bear. attorney steve Jensen believed in the masimo mission and urged 

his partners to continue with the case, fearing that if the company did not win, it 

could literally mean a great many unnecessary deaths in the future. the Knobbe 

firm assembled a small army of personnel on a floor of a hotel in downtown los 

angeles. mohamed diab thought it looked like a war room, with an It specialist, 

computers everywhere, and steve Jensen writing the trial strategy like a field 

general. to reassure his clients, attorney Joe re told masimo that it had many 

legal “smoking guns” with which to go after nellcor and its parent company at the 

time, mallinckrodt, while in most trials of this kind, there was only one. this was 

a prescient comment. on friday, march 26, 2004, the 27-day trial was over and 

masimo won to the tune of $270 million overall, with a 14.8 percent royalty to be 

paid to masimo by nellcor each year for use of masimo technology. everyone at 

masimo was hugely relieved, but it was too early to celebrate; with appeals, it might 

be years to collect. through appeals and another trial, however, masimo persisted, 

and nellcor lost. a med tech david had brought down a med tech Goliath, and 

masimo showed the world that “right is might” and no just fight was impossible to 

win, if you had enough determination, persistence, and truth on your side.

> our legal Team: As a lawyer, we think of Joe Re as bigger than life. He’s King Kong. He 

doesn’t leave anything behind. Together with Steve Jensen, they formed a simply unstoppable 

team. During our patent litigation, Steve was detail oriented, found all the facts, did all the 

discovery work, and came up with the legal strategy along with Joe. And when Joe Re went in 

front of that jury and displayed his mastery, our ultimate success was assured, no matter how 

much trepidation we had going in and during the trial.

The patent trial victory was cleansing and healing, and the wonderful result was heavily dependent 

on Steve, who was literally tireless. He would work all night leading up to and during the weeks of the 

trial. At 4:00 or 5:00 in the morning he’d hand off the questions that Joe would ask the witnesses 

the next day. And then Steve would go take an hour nap, shower up and come back to court with us. 

He lost 30 pounds during that 4- to 5-week period, and he and Joe won us our life as a company.

“wHaT an Honor it was for me and my partners at Knobbe to present the Masimo story to 

eight strangers, a jury. as each day passed during that six-week patent infringement trial,

International 
Advocates

as told by Katsuyuki Miyasaka, christian Poets, 
and atsuhiro sakamoto

masimo’s international reach was expanded in february of 1998 with deals with 

datascope corp. and Invivo research. datascope put the company in front of a 

worldwide market when it agreed to integrate masimo set® into its monitors. But 

before that, Japanese companies, nec medical and atom, had agreed to introduce 

masimo to Japan, and a uK company, Kontron, agreed to do so in europe. this was 

quickly followed by Gs electromedical, a German company whose primary products 

were defibrillators and monitors used in emergency medical applications. Gunter 

stemple, President of Gs electromedical, called masimo technology a “quantum leap 

in performance and reliability,” which was quite a recommendation for the rest of 

the european market. With the Group Purchasing organization structure in the u.s. 

hindering market expansion for so long, masimo’s necessary outreach to international 

markets turned into a blessing long-term, and some special champions of our work 

made a big difference with their support, encouragement, and advice.

Katsuyuki Miyasaka

> Dr. Miyasaka was an anesthesiologist in the National Children’s Hospital in Japan. He did 
original studies for us in Japan when NEC was implementing Masimo SET® into their products. 
His data gave us a clue that eventually helped us figure out how to make a pulse oximeter that 
was good even on cyanotic patients. Even better, he pushed us to complete rainbow,® which was 
major, by telling Joe over dinner, “If you don’t do it, no one else will!”

“mY inTereST in pulSe oximeTrY began over 30 years ago, particularly regarding its use 
in clinical settings for neonates, and in pediatric anesthesia and critical care. i was one of the 
first to promote the use of pulse oximetry in Japan through my involvement in conferences 
on oximetry use and publication of scientific and clinical papers from the late 1980s. My 
scientific and clinical association with Masimo started in 1993 when Mr. Joe Kiani visited 
Japan, from which time i became involved in Masimo pulse oximeter product development. 
clinical data from physicians in the field provided important feedback to Masimo and led to 
suggestions for product improvement.

“there was little interest in pulse oximeter use at the beginning because in adult anesthesia 
the monitor always showed 100%, but the situation was quite different in pediatrics as 
patients were always labile and fragile.

“My focus on such issues as the influence of venous pulsation on motion artifact during 
poor perfusion in pediatric patients and the use of clinical data analysis contributed 
to the improvement of Masimo Set® technology. the reduction of false alarms due to 
motion artifact was of utmost importance in establishing clinician acceptance of pulse 
oximetry. i believe its use in adult medicine was based in part upon its success in pediatric 
medicine. i find many other issues, such as the importance of noninvasive measurement of 
hemoglobin and dyshemoglobins, to be of great interest.

“as a physician researcher specializing in pediatric anesthesia and critical care, i have been 
aware of the importance of pulse oximetry in pediatric anesthesia and Nicus and have 
tried to deepen understanding of the issues involved through clinical studies that provide 
information to the medical community, both in Japan and overseas. i look forward to further 
development of products by Masimo in the future.”

christian Poets

> Christian rolled up his sleeves, tested our product (when it was in a little blue box) on babies 
in his care, collected a lot of great data, and challenged us to make it better. He urged us to 

improve pulse rate algorithm, and we did. Because of his help, data, 
prodding, and then his publications, he showed our competitor’s 
product not only gave false readings but they also missed true 
alarms. None of this ever showed us as perfect but all of a sudden 
we were seen as much better than whatever was out there.

these recordings (including the raw red-to-infrared data), 
which apparently helped the Masimo team a great deal 
to improve their software. i did this because i saw the 
potential: there was never any money involved.

“i waS conTacTed in late 1993 by trevor Jones, a senior 
manager from a british Monitor company, Kontron (Watford, 
uK). they had supported us by designing a transcutaneous 
Po2 monitor for home use in infants (to notify parents 
of severe hypoxemia potentially leading to sudden infant 
death syndrome (SiDS)). We had chosen transcutaneous 
monitoring because pulse oximetry was nowhere near 
suitable as a home monitor at that time. trevor told me 
he had had contacts with a person called Joe Kiani, who 
had developed a new, motion resistant pulse oximeter, 
and asked whether i was interested in meeting this guy – 
which i certainly was, as i had never liked the idea of using 
transcutaneous oxygen monitors in the home environment, 
and was thus keen to meet somebody who promised he had 
solved its main problem, i.e., motion artifact! 

“Joe walked into my office a few weeks later, and was proud 
to present me his pulse oximeter. However, when i tested 
this device in our patients on the neonatal intensive care 
unit, i saw its potential, but in my opinion, there were still 
far too many false alarms due to motion. i told him that, 
and he asked me whether i would be willing to record 
saturation data in some really difficult infants on our Nicu 
(with a lot of motion, but also recurrent true hypoxemia), 
which i was. Masimo sent equipment, and i then started 

“What struck me already during our first encounter was Joe’s 
determination to really improve pulse oximetry, not just to 
make money. He was burning to make a potentially extremely 
helpful technology better, more user-friendly and reliable, and 
he could accept/respond to critique. i gave him a really hard 
time in 1993, when he was so proud about his new invention, 
and it was certainly not easy for him to swallow my rather 
blunt statement: ‘it’s better than what i have seen from your 
competitors, but not what i expect from a really good device.’ 
He did not ignore my critique, but took it as a challenge that 
ultimately helped Masimo to become better.”

atsuhiro sakamoto

> Dr. Sakamoto met Joe Kiani in Tokyo in 2007 and provided Joe 
with information about the style of Japanese medical practice and 
about the Japanese medical business. Dr. Sakamoto also helped 
study noninvasive hemoglobin and rainbow acoustic monitoring 
as the head of the Masimo Japan Working Group (MJWG) and has 
been instrumental in helping us better shape our products for 
assisting patients in Japan.

“in Japan, since 2008, i have been a leader in reviewing 
over 1,000 clinical data on SpHb® while collaborating with 

15+ key medical institutes. i organized an SpHb study 
group called MJWg with 35+ key teaching hospitals on the 
subject of SpHb. MJWg shares its clinical study data with 
those key teaching hospitals, and this collaboration has 
contributed to a greatly improved product. MJWg not only 
contributed to various clinical studies on SpHb, but also to 
the penetration of Masimo SpHb into the Japanese market. 
We consider this to be a great asset to the health of our 
country’s people.

“i also have a strong interest in enhancing patient safety. For that 
purpose, i am working on a project for our hospital to improve 
patient respiratory management. i find Masimo RRa® and Spo2 
greatly contributes to increasing patient safety at clinical sites.

“our hospital resources, rather than being abundant, are 
limited. therefore, it is important for us to know how to 
manage patient safety in critical care and in the general ward 
with our limited number of medical staff. Just applying a 
monitor to a patient on the general ward is not enough. Vital 
signs should be monitored continuously and collected in real 
time and should be closely observed and analyzed at a central 
Station for the best patient care.

“the greatest importance is how quickly our staff members 
grasp a patient’s medical condition and how quickly we 
can take necessary actions for a patient. i am assured 
that Masimo products with Spo2, RRa, Hb, and a central 
monitoring system maximizing our hospital laN network 
system are powerful tools for our medical staff to increase 
patient safety throughout our hospital.”

The Masimo 
Foundation

as told by Jim Bergman

the masimo foundation for ethics, Innovation and competition in Healthcare is a 

non-profit organization we formed to facilitate our corporate philanthropy. during 

the first quarter of 2010, we provided a monetary gift and an in-kind contribution 

of pulse oximetry equipment and supplies to support the foundation’s efforts. our 

$10 million gift to the foundation represented a portion of the multi-million dollar 

payment received in January 2010 from the antitrust victory against nellcor/tyco 

Healthcare. the foundation’s established purpose was to encourage and promote 

various activities, programs, and research opportunities designed to improve 

patient safety and deliver advanced healthcare to people worldwide that may not 

otherwise have access to lifesaving technologies. 

In addition, the foundation is meant to support third-party research, development 

initiatives, and clinical studies designed to expand the healthcare industry’s ability 

to provide better and more cost-effective solutions and protocols for healthcare 

delivery throughout the world. finally, the foundation is intended to provide special 

attention to those causes whose ultimate goals are ethical – focused on doing the 

right thing for the right reasons – and designed to create healthy competition, 

which masimo believes is the ultimate answer to lower health care costs in the 

u.s. and throughout the world. the masimo foundation is dedicated to improving 

patient care through philanthropic programs and research initiatives that foster 

an environment of robust and honest competition, and enhance caregiver access 

to cost-effective and innovative healthcare solutions. the masimo foundation is 

also a family affair with sarah, mrs. Joe Kiani, serving on the board. 

as we look back over the past quarter century and consider our struggles along 

the way, we feel particularly blessed to have made it this far because there were 

many times when the future seemed shaky, as the following story from a masimo 

foundation board member illustrates.

The Patient 
Safety Movement

as told by President William Jefferson clinton

President William Jefferson clinton 

> In the summer of 2012, Joe Kiani spent over a week with President Clinton in Africa. It was part 

of a commitment Joe had made to help the President with his work for the Clinton Global Initiative 

(CGI). They became friends, and Joe told President Clinton something that was fascinating but 

horrifying – that three million people die worldwide every year from deaths that are preventable. 

More than 200,000 of those deaths occur in the U.S. The two agreed that the goal of healthcare 

in the new millennium should be more than simply providing people access to healthcare, but also 

advancing a healthcare system that assures patient safety and dignity. 

“i’ve been impressed by Joe’s commitment to end all deaths due to preventable 

medical circumstances. i believe that the goal of the Patient Safety Movement can be 

accomplished--and because it can it has to be done. 

“i know big goals can be achieved. Since 2005, members of the clinton global 

initiative, with their thousands of commitments to action, have had a positive 

impact on more than 400 million people in 180 countries. being a cgi member entails 

making a commitment and doing your best to keep it. the cgi staff works year round 

to help our members develop and keep their commitments. they draw upon each 

other’s strengths and create new partnerships to put their ideas into action. We call it 

‘mobilizing for impact.’ 

“this is exactly what Joe Kiani has demonstrated in building Masimo, and in creating 

the Patient Safety Movement. on their 25th anniversary, i’d like to congratulate Joe 

and the people at Masimo for helping us achieve a healthier world, and commit to doing 

my part until the goal of zero preventable deaths becomes a reality.”

spo2 screening was conducted on 39,821 newborn babies, preductally (palm of right hand) and postductally (either foot) 
before routine physical examination. the baby was considered to be screening positive if: 1) either preductal or postductal 
spo2 measurement was <90%; 2) if in three repeat measurements, both preductal and postductal spo2 were <95%, or the 
difference between the two measurements was >3%.

In period one, the baseline rate for severe roP in two centers, both using nellcor pulse oximetry, is established. 
In period two, the oxygen targeting policies, caregivers, and patient characteristics were the same at both centers, 
but only center a switched to masimo set®, which led to a significant reduction in roP (from 12% to 5%). In period 
three, center B switched to masimo set® and experienced a reduction in roP from period two (from 13% to 6%).

FirST eVer noninVaSiVe FracTional Spo2 meaSuremenT 

until now, pulse oximeters could only measure and display 

functional oxygen saturation (Spo2). So, when patients had 

elevated carboxyhemoglobin (from carbon monoxide poisoning) 

and/or elevated methemoglobin (adverse reaction to more than 30 

common drugs used in hospitals, like caines, nitrates, and Dapsone), 

the displayed functional oxygen saturation overstated the actual 

oxygen saturation value.

Masimo Spfo2™* is the first truly fractional, noninvasive oxygen 

saturation measurement. Spfo2 allows more precise arterial 

oxygenation assessment in patients with elevated dyshemoglobins 

– common throughout the hospital and pre-hospital settings – as 

compared to functional oxygen saturation (Spo2). as a result, Spfo2 

should enable earlier interventions and more timely therapeutic 

decisions. For example, in a patient who is a smoker with an Spo2 

of 97%, carboxyhemoglobin level of 12%, and methemoglobin of 

1%, if Spfo2 were available, it would be displayed at 84%. it is well 

accepted that clinicians would frequently make different diagnostic 

and therapeutic decisions at an oxygenation of 84% versus 97%.

TFa-1™ diSpoSable ForeHead SenSor*

expanding its versatility of sensors, Masimo now offers the tFa-1 

transflectance forehead adhesive sensor as an alternative to 

traditional digit sensors. the forehead provides rapid detection of 

saturation changes compared to digit sites during low perfusion and 

offers easy access during surgery, resuscitation, and in patients with 

finger deformities or when the digit is not accessible.

While hemoglobin is one of the most common laboratory tests performed, most 

clinicians are unaware of variation that should be expected when comparing 

hemoglobin measurements – both within and between various device models. 

this is because clinicians do not typically measure hemoglobin more than once 

in the same patient at the same time. Variation is induced by physiology, blood 
sampling technique, device methodology, and individual device calibration.1

Fluid administration is one of the most common hospital interventions. although it is critical to improving patient status 
and enabling end organ preservation, unnecessary fluid administration is associated with increased morbidity and mortality.1 
While commonly used, traditional “static” measurements such as central venous pressure are not reliable to predict whether 

a patient will respond to volume administration with an increase in blood flow (stroke volume or cardiac output) and therefore 

are not effective to guide fluid management decisions.

changes in expired respiratory gas can be an early indicator of an adverse respiratory event. Hypoventilation, hyperventilation, 

airway obstruction, and other potentially life-threatening conditions can be rapidly detected with capnography – enabling 

clinicians to intervene as early as possible. capnography and gas monitoring also provide insight into the effectiveness of the 

anesthesia breathing circuit, aiding clinicians in maintaining proper gas concentrations and ventilation levels.

nomoline™ – no moiSTure Sampling line

Nomoline technology eliminates common problems associated with conventional 

sidestream gas analysis. incorporating a special polymer and a hydrophobic bacterial 

filter, the Nomoline allows water in the sampling line to evaporate into the surrounding 

air, while leaving oxygen, carbon dioxide, and anesthetic gases unaffected. Specially 

designed for low-flow applications and functional in any orientation, Nomoline technology 

can be used in any clinical application for all types of patients from neonates to adults. 

Nomoline is designed to extend the product life in single-use applications, such as high

Halo index is a new indicator for cumulative trending assessment of the

patient crisis and manifests through subtle and often undetected changes 

in multiple physiologic parameters. Masimo designed Halo index to mimic 

the systematic approach that expert clinicians use in assessing patient 

physiologic deterioration – analyzing the patient history and extracting key 

vital sign parameter characteristics to assess global patient status. Halo 

index currently uses available Masimo parameters but is scalable to include 

additional information from the patient data repository. each parameter’s 

significance is weighted and combined into the Halo index, a single 

displayed number with a range from 0 to 100 that provides a cumulative 

trending assessment of global patient status. increases in Halo index 

suggest physiologic deterioration and may indicate a need for clinicians 

to more closely assess the patient.

For pediatric patients requiring continuous monitoring at home, Masimo Set® 

offers advantages for parents caring for special needs children – dramatically 

reducing false alarms during motion and low perfusion that can complicate an 

already difficult situation.

adding a SaFeTY neT in poST-acuTe care

as hospital costs rise, more patients are receiving care in long term acute care and 

skilled nursing facilities. a major challenge in these facilities is weaning patients off 

ventilator care, which can put patients at increased risk of adverse events. Post-acute 

care facilities integrating Masimo Set® bedside pulse oximeters and Patient SafetyNet 

remote monitoring and notification systems have experienced considerable reduction 

in rapid response activations as well as emergency “transfer outs.”

During sleep lab monitoring, conventional pulse oximetry fails to provide 

the fidelity and accuracy required to help clinicians detect clinically 

relevant physiologic events. Masimo Set® technology is integrated in 

leading sleep lab monitoring systems, enabling clinicians and patients to 

benefit from its unmatched reliability in this challenging environment.

“ Masimo technology has raised the

carbon monoxide poiSoning 
wiTH Spco®

carbon monoxide (co) poisoning is the most common 
cause of poisoning in industrialized countries,1 but is often 
misdiagnosed because its symptoms are similar to the flu, 
and moderate poisoning is possible with no symptoms at all.2

a deadlY poiSon reVealed wiTH Spco

our first rainbow® measurement was noninvasive carboxyhemoglobin (Spco), helping 

clinicians identify and assess co levels in the blood. a recent study at Medical 

university Vienna in austria assessed 32,396 emergency Department patients with 

Spco by Pulse co-oximetry. of 32 patients with a diagnosis of co poisoning, 22 

(69%) would not have been identified without an elevated Spco measurement.2

in another study, researchers examined data from the undersea Hyperbaric Medicine 

Society’s co poisoning surveillance system (supported by the centers for Disease 

control) and found that patients who were initially measured using Pulse co-oximetry 

had an almost one-hour reduction in time from the end of co exposure to treatment.3

“We believe that all 50-plus people in the hotel 

would have been dead at dawn if it were not for this 

lifesaving intervention from Masimo.”

Skip kirkwood, mS, Jd, emT-p
chief, eMS Division, Wake county Dept. of emergency Services , Raleigh, Nc

SaVing liVeS eVerY daY 

in emergency medical services, Spco is helping protect both victims and first 

responders from the dangers of co poisoning. Spco helps paramedics and emergency 

medical technicians to identify and assess co levels in the blood. Spco is also helping 

firefighters reduce the risk of co poisoning that they face every day. Just one severe 

co poisoning nearly doubles the risk of premature death, and consistent co exposure 

may cause long-term heart and brain damage.4,5

When even mild levels of co are circulating in the blood, the heart and brain are robbed of 

critical oxygen. this can cause mental confusion that leads to poor decision making and 

also increases the risk of heart disease or stroke – two conditions already accounting 

for nearly 50% of on-duty firefighter deaths.6 these factors are why industry-leading 

organizations have lined up to support co education, and the National Fire Protection 

association (NFPa) recently released an updated Fire Rehabilitation Standard (NFPa 

1584) requiring firefighters exposed to smoke at incident scenes and during training to be 

assessed for carbon monoxide (co) poisoning.

see a compelling analogy with our Root platform. the thinking 

was that someone needed to do for patient monitoring what
