MightySat is a fingertip pulse oximeter designed for general wellness and health applications including sports, fitness, and relaxation management. MightySat provides noninvasive measurements of oxygen saturation (SpO2), pulse rate (PR), perfusion index (Pi), PVi® (studies show changes in PVi may indicate changes in hydration, breathing effort, perfusion, or other factors1-3) and RRp™ (respiration rate based on the plethysmographic waveform). MightySat features Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry. MightySat displays all noninvasive measurements in real time, and users can also display and track their data through the Masimo Personal Health app for iOS® and Android® compatible devices.

The WTA SS&M team’s primary health care providers (PHCPs—licensed physical therapists and certified athletic trainers) will use MightySat at WTA tournament events to help support the general health, wellness, and fitness of elite women's tennis players. “We’re fortunate to have this new technology in the training room and on the court at the WTA. This equipment will aid our PHCPs in assessing player health and allow them to better service the immediate needs of our athletes,” said Kathleen Stroia, SVP SS&M and Transitions for the WTA.

“We have been encouraged by the feedback we have received from elite athletes and trainers about how MightySat helps them improve their health and performance. For example, they use Masimo’s unique accuracy to decide on how hard to train,” said Joe Kiani, Founder and CEO of Masimo. “We are excited to work with the WTA to help them use Masimo’s breakthrough noninvasive technologies to make a meaningful difference in women’s tennis. We have long been big fans of the sport and are excited to help these peak performing athletes reach even greater heights.”

MightySat is intended for general wellness and health applications. For medical applications, Masimo offers MightySat Rx, which is available to medical professionals.

About Masimo

Masimo (NASDAQ: MASI) is a global leader in innovative noninvasive monitoring technologies. Our mission is to improve patient outcomes and reduce the cost of care. In 1995, the company debuted Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry, which has been shown in multiple studies to significantly reduce false alarms and accurately monitor for true alarms. Masimo SET® has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates,1 improve CCHD screening in newborns,2 and, when used for continuous monitoring with Masimo Patient SafetyNet™* in post-surgical wards, reduce rapid response activations and costs.3,4,5 Masimo SET® is estimated to be used on more than 100 million patients in leading hospitals and other healthcare settings around the world,6 and is the primary pulse oximetry at 17 of the top 20 hospitals listed in the 2017-18 U.S. News and World Report Best Hospitals Honor Roll.7 In 2005, Masimo introduced rainbow® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb®), oxygen content (SpOC™), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), Pleth Variability Index (PVi®), and more recently, Oxygen Reserve Index (ORi™), in addition to SpO2, pulse rate, and perfusion index (Pi). In 2014, Masimo introduced Root®, an intuitive patient monitoring and connectivity platform with the Masimo Open Connect® (MOC-9®) interface, enabling other companies to augment Root with new features and measurement capabilities. Masimo is also taking an active leadership role in mHealth with products such as the Radius-7® wearable patient monitor, iSpO2® pulse oximeter for smartphones, and the MightySat™ fingertip pulse oximeter.
