Closer to the Heart®

Closer to the
      Heart

For over 20 years, Masimo has been the leader in developing 

breakthrough noninvasive monitoring technologies. But what 

sets Masimo apart is not just what we do, but why and how we

do it. We call it staying “Closer to the Heart”, an attitude and

philosophy that permeates everything we do.

Closer to the Heart means always doing what is right in our hearts – not just what 

is immediately rewarding. By staying Closer to the Heart, we remain focused on:

>  Solving unsolvable problems by getting to the heart of the issue

>  Protecting patients by having the heart to go after the clinical solutions 

that are needed – even when the path is long and uncharted

>   Innovating for the future to allow clinicians to get at the heart

of what is wrong with their patients

A Letter from the Chairman & CEO

DELIVERING ON OUR MISSION AND GUIDING PRINCIPLES

Over 20 years ago, Masimo started with a bold mission to improve patient outcomes and reduce the 

cost of care by taking noninvasive monitoring to new sites and applications. We also set forth guiding 

principles that stay with us today:

>   Remain faithful to your promises

>   Strive to make each year better than the year 

and responsibilities

before both personally and for the team

>   Thrive on fascination and accomplishment

>  Make each day as fun as possible

and not on greed and power

>  Do what is best for patient care

In Masimo’s 20th anniversary year, we celebrated by launching more breakthrough noninvasive 

measurements, growing the number of customers and partners, and expanding the markets for our 

products. In the process, we delivered record 2009 fi nancial results in a challenging global economy.

Helping Improve Fluid Management with PVI®

Fluid administration is one of the most common hospital interventions. Although it is 

critical to improving patient status and enabling end organ preservation, unnecessary 

fl uid administration is associated with increased morbidity and mortality.

ASSESSING FLUID RESPONSIVENESS

Masimo continuous and noninvasive Pleth Variability Index (PVI) 

to help assess which patients will become hemodynamically 

has been shown in multiple studies to help clinicians assess fl uid 

unstable with the addition of Positive End Expiratory Pressure 

responsiveness in adult surgical and intensive care patients 

(PEEP), which may allow clinicians to more carefully select 

under mechanical ventilation.16, 17 PVI has also been shown 

ventilator settings and monitor eff ects more closely.

AIDING CLINICIANS IN PATIENT RISK REDUCTION

A recent randomized trial showed that compared to 

risk – as evidenced by lower lactate levels.18 By helping 

standard care without PVI, clinicians using PVI were able to 

clinicians maintain appropriate fl uid and oxygen levels

improve fl uid management and as a result, reduce patient

Earlier and Better Decisions to Improve Patient Care

With the expansion of Rainbow measurements to include total hemoglobin, Masimo

A REVOLUTIONARY DEVICE FOR A VARIETY OF CLINICAL SETTINGS

Hemoglobin is one of the most commonly ordered tests in both hospital and non-hospital 

settings because it is critical to assessing anemia. However, traditional lab testing 

requires a painful needle stick for the patient, time-consuming blood draws for the 

clinician, and typically provides delayed results.

The Pronto-7 represents a breakthrough new solution for measuring hemoglobin 

in just 45 seconds – without needles, time-consuming laboratory analysis, or the 

risk of blood contamination or hazardous medical waste. The Pronto-7 is also the 

fi rst Masimo device to feature Rainbow 4D™ technology for faster and more 

accurate spot-check hemoglobin measurements.

The palm-sized Masimo Pronto-7 – with dimensions at just 5.1” x 2.8” x 1” 

and weight of 10.5 ounces – puts the power of noninvasive hemoglobin 

spot-check testing into any clinician’s hands in almost any environment, 

including hospitals, clinics, blood donation centers, and emergency 

medical services. Operation is easy and intuitive with the Pronto-

7’s touch-screen interface. And because of the 

device’s embedded 802.11 b/g and Bluetooth 

communication capability, wireless printing or

with future upgrades to allow for wireless 

transmission to EHR systems.
