Masimo Unveils iSpO2 Pulse Oximeter for Android

Masimo (NASDAQ: MASI) today announced that its award-winning iSpO2® pulse oximeter is now available for AndroidTM, along with the companion iSpO2 app downloaded from the Google PlayTM Store. With the release of iSpO2 in the popular Android operating system, more consumers than ever now have access to Masimo SET® Measure-through Motion and Low PerfusionTM pulse oximetry – the same technology used in leading hospitals worldwide.

iSpO2 provides accurate, real-time oxygen saturation (SpO2), pulse rate (PR), and perfusion index (PI) readings – ideal for anyone who desires access to accurate health data through their mobile devices.

Stig Severinsen, Ph.D. in medicine, a four-time World Champion freediver and owner of multiple Guinness World Records, including history’s longest breath-hold of 22 minutes, uses iSpO2 as part of his regimen.

“Training for extreme records under extreme conditions is always a huge challenge,” Severinsen said. “In such situations it is of great value to be able to perform noninvasive and accurate measurements of my heart rate and oxygen levels with a state-of-the-art device. Masimo has created a clever device that not only displays your measurements in real time – even during motion and states of low perfusion in cold conditions – but it also allows you to store and share data with people in your team.

“I would recommend Masimo’s iSpO2 to anyone interested in health and fitness – understanding what goes on inside your body is paramount to improving performance,” he added.

Dr. Mark Hom, M.D., co-author of forthcoming exercise books with three-time Tour de France champion Greg LeMond, and Dr. Glenn A. Gaesser, Ph.D., said: “Although we advocate intense training, we don’t recommend that healthy athletes train to the point of oxygen desaturation (i.e., cyanosis). However, our preliminary testing with the iSpO2 has shown that it has the accuracy and repeatability to show subtle changes in athletic oxygenation: specifically in warm-up, steady state, super high intensity, and recovery. And as an added benefit, the iSpO2 is compact enough to be useful when training on the road or track”

iSpO2® for Android provides oxygen saturation (SpO2), pulse rate (PR), and perfusion index (PI).


“This pulse oximeter is without a doubt the best one available for the consumer market,” said Dr. Kirk Shelley, M.D., PhD, professor of anesthesiology at Yale University in New Haven, Conn. “Masimo uses impressive digital signal processing combined with proprietary light emitting diode (LED) technology. If you need a serious pulse oximeter, this is the one to get.”

iSpO2 – extremely lightweight at just 232 grams or about 0.5 pounds – also displays the pleth waveform and Signal IQTM so users can visually assess where the pulse is occurring and the quality of the measurement even during motion artifact. iSpO2 can also trend, store, and email up to 12 hours of measurement history in the global standard, .CSV file format, allowing consumers to easily share data through their mobile device email application.

The performance of Masimo SET pulse oximetry is proven by more than 100 independent and objective studies and thousands of clinical evaluations to accurately monitor blood oxygen saturation even in the most challenging conditions, including patient movement and low peripheral perfusion. The pulse oximetry standard-of-care at leading hospitals worldwide – including by eight of the top 10 hospitals on the U.S. News & World Report Best Hospitals Honor Roll (2013-2014) – Masimo SET® virtually eliminates false alarms1 and increases a clinician’s ability to detect life-threatening events.

About Masimo

Masimo is a publicly traded company (NASDAQ: MASI) based in Irvine, California. Masimo is the leading brand of hospital pulse oximeters Reference 1 because they provide accurate measurements when other pulse oximeters fail by using a revolutionary, patented invention called Signal Extraction Technology® open paren (SET®)close paren. Masimo SET® uses five parallel signal processing engines that measure through challenging conditions, including movement and low blood flow. With MightySat, the same high-performing Masimo SET® technology is now available for general wellness and health applications.
