Known for its exceptional accuracy and reliability during challenging atmospheric condition, such as motion and depression perfusion, Masimo is bringing its expertise in betoken processing, photonics, and bio-sensing to consumers looking to have control of their personal wellness, make better health decisions, and monitor their overall physiological status. Paired via secure Bluetooth®
to the Masimo Wellness™ smartphone app, Masimo W1 provides continuous health data, unlocking meaningful, actionable insights, with accuracy unheard of in a wearable or watch.

Launching aslope the Masimo W1 is Personal SafetyNet™, a paid subscription service integrated within the Masimo Health app that gives users access to sophisticated reporting tools to assist them review their physiological status over fourth dimension. In addition, Personal SafetyNet facilitates sharing data with family unit members, fettle trainers, health coaches, and where immune, healthcare providers, and even allows users the ability to set up virtual visits with doctors.

The Masimo W1 for consumers volition be available for directly-to-consumer purchase starting immediately at world wide Masimo W1 comes with the Personal SafetyNet subscription service for consumers. Too arterial oxygen saturation and pulse rate, Masimo W1 can besides measure respiration rate, pleth variability index (PVi®), perfusion index, pulse rate variability (PRV), heart rate variability (HRV), steps, and, under limited market release terms, Hydration Index (How-do-you-do™). As part of a future update, Masimo W1 will besides be able to measure temperature and VO2Max and provide 24/vii health information tracking and oversight.

Hydration level has been one of the virtually sought out parameters past athletes, vocalists, and others seeking to optimize their performance. Since creating PVi – which allows clinicians to assess fluid responsiveness of mechanically ventilated patients – well-nigh xv years agone, Masimo has been working to invent a way to bring that measurement to consumers and those not on ventilators. Proper hydration is widely recognized equally an of import aspect of health and functioning, and lack of proper hydration affects many physiological parameters, as the body works to restore homeostasis. Masimo W1 establishes your hydration baseline, helping yous understand your hydration level, which non simply affects athletic performance and fatigue, just can behave significant risks, particularly for users with conditions similar congestive heart failure. Whether you’re an elite athlete, a vocalizer, living with a chronic affliction, or merely keen to gain more insight into your body’s physiological status, Masimo W1 with Hydration Index represents a breakthrough solution to better understanding and direction of hydration.

Olympic silvery medalist Morgan Pearson commented, “Masimo W1 is a gamechanger. As a professional triathlete, I’m always looking to optimize my functioning in every way possible. With Masimo W1 I can continuously monitor lots of vital signs, even my level of hydration. This essential continuous data volition help me runway and amend my physiological performance in the virtually demanding of race conditions.”

Dotsie Bausch, also an Olympic silver medalist, added, “Masimo W1 delivers the next generation of accuracy in wearables. I trusted Masimo technology to catapult me onto the Olympic podium as the oldest competitor in history in my field of study. Masimo delivers superior accuracy through movement, which is the gilt edge whatever athlete is looking for to produce their very best, every single time.”

Masimo is likewise entering the general launch phase of a medical version of Masimo W1 for use in medical applications outside the U.South., with additional measurement capabilities such every bit spot-bank check electrocardiogram (ECG), atrial fibrillation (A-fib) detection, and more. Benefiting from Masimo’due south expertise in hospital connectivity and hospital automation, the medical Masimo W1 will also be bachelor for employ in telehealth and telemonitoring applications via Masimo SafetyNet®
and Personal SafetyNet for healthcare providers and payers, every bit well every bit individual use. For patients taking opioids to reduce pain or recovering at abode after surgery or illness, as well as patients with chronic conditions (such as centre failure, COPD, or cancer), Masimo W1 will stand for a convenient, reliable remote monitoring and telehealth solution enabling hospitals and clinicians to proactively go on track of their patients’ physiological condition from distant, even as patients go nearly everyday tasks at home. A natural complement to the Masimo SafetyNet remote patient monitoring platform, Masimo W1 enables wireless transmission of patient data to the Masimo SafetyNet app and Masimo’s secure information deject, where information technology will be reviewed in near-real time by remote monitoring teams in centralized locations for signs of physiological reject or sudden changes, such as falls or spikes in heart rate.

In Kingdom of saudi arabia, where Masimo W1 is already approved for use in medical applications, Dr. Bakhsh, Head of the Middle Part Unit at Prince Sultan Cardiac Center, said, “Nosotros have begun using Masimo W1 with Masimo SafetyNet for remote patient monitoring of our chronic center failure patients. The scout is very comfortable to wear, and the continuous Masimo measurements give us confidence to help continue our patients condom.”

Dr. Chaudhry, Chief Clinical Data Officeholder (CCIO) and Main Data Officeholder (CIO) at Cambridge University Hospitals NHS Foundation Trust (CUH), said, “Nosotros take deployed Masimo Patient SafetyNet™ on our Intermediate Dependency Care Unit for continuous monitoring with pulse oximetry, and believe it has made a genuinely positive touch on the rubber of our patients. My initial feel with Masimo W1, the Masimo Wellness app and Personal SafetyNet monitoring service has been very positive. Equally we go forward caring for patients, whether in the infirmary or at home as part of the virtual wards we are setting upward, I am sure that this technology will be an excellent addition, supporting us in the delivery of ever increasing high-quality remote care for patients underpinned by personal, timely, and accurate clinical information.”

Dr. Amin, Professor of Medicine and Endowed Chair of Medicine at the University of California, Irvine, noted, “Masimo continues to innovate elegant noninvasive solutions to complex bug. The release of the Masimo W1 sentry raises the bar on home wearables by providing pulse oximetry based on industry-leading SET®
engineering science and continuous monitoring features in a wrist-worn device. By doing so, we can follow our health and fitness beyond the abode, to any location that has jail cell phone connectivity. I have personally worn Masimo W1 and am impressed by its comfort and stylish look—while able to continuously monitor my oxygen level, follow my step count, and rails other health parameters, both at rest and during activeness.”

Joe Kiani, Founder and CEO of Masimo, said, “With over thirty years of experience in medical monitoring and telemedicine, we are excited to bring the first wearable device to offer accurate and continuous pulse oximetry, hydration index, and other health measurements to consumers. The SET®
technology we invented for hospitals transformed patient monitoring, saved lives, and reduced the toll of care. Based on the feedback we take received from those who have tested Masimo W1 during the limited market release phase, we believe this watch volition ameliorate lives.”

In the U.S., Masimo W1 for utilise in medical applications is awaiting FDA clearance.
