Masimo (NASDAQ: MASI) today announced the full market release of the Masimo W1™ health watch for consumer use. The first of its kind, the Masimo W1 offers accurate, continuous measurements and insightful health data – from the leader in hospital pulse oximetry – in a personal, lifestyle-friendly, wrist-worn wearable. Building on Masimo’s decades of leadership in creating revolutionary noninvasive blood parameter monitoring solutions, Masimo W1 provides for the first time in a watch format, accurate, continuous monitoring of oxygen saturation (SpO2), as well as pulse rate, respiration rate, and more, and, in a limited market release, hydration index – for consumers wanting to better understand their overall health, improve their fitness, or share their health data with friends and family. Taking 86,400 measurements a day for second-by-second trending, the Masimo W1 watch represents the future of personal health.
Known for its exceptional accuracy and reliability during challenging conditions, such as motion and low perfusion, Masimo is bringing its expertise in signal processing, photonics, and bio-sensing to consumers looking to take control of their personal health, make better health decisions, and monitor their overall physiological status. Paired via secure Bluetooth® to the Masimo Health™ smartphone app, Masimo W1 provides continuous health data, unlocking meaningful, actionable insights, with accuracy unheard of in a wearable or watch.
Launching alongside 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 help them review their physiological status over time. In addition, Personal SafetyNet facilitates sharing data with family members, fitness trainers, wellness coaches, and where allowed, healthcare providers, and even allows users the ability to set up virtual visits with doctors.
The Masimo W1 for consumers will be available for direct-to-consumer purchase starting immediately at www.masimo.com/masimo-w1. Masimo W1 comes with the Personal SafetyNet subscription service for consumers. Besides arterial oxygen saturation and pulse rate, Masimo W1 can also 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 (Hi™). As part of a future update, Masimo W1 will also be able to measure temperature and VO2Max and provide 24/7 health data tracking and oversight.
Hydration level has been one of the most sought out parameters by athletes, vocalists, and others seeking to optimize their performance. Since creating PVi – which allows clinicians to assess fluid responsiveness of mechanically ventilated patients – nearly 15 years ago, Masimo has been working to invent a way to bring that measurement to consumers and those not on ventilators. Proper hydration is widely recognized as an important aspect of health and performance, and lack of proper hydration affects many physiological parameters, as the body works to restore homeostasis. Masimo W1 establishes your hydration baseline, helping you understand your hydration level, which not only affects athletic performance and fatigue, but can carry significant risks, especially for users with conditions like congestive heart failure. Whether you’re an elite athlete, a vocalist, living with a chronic illness, or just keen to gain more insight into your body’s physiological status, Masimo W1 with Hydration Index represents a breakthrough solution to better understanding and management of hydration.
Olympic silver medalist Morgan Pearson commented, “Masimo W1 is a gamechanger. As a professional triathlete, I’m always looking to optimize my performance in every way possible. With Masimo W1 I can continuously monitor lots of vital signs, even my level of hydration. This essential continuous data will help me track and improve my physiological performance in the most 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 discipline. Masimo delivers superior accuracy through movement, which is the golden edge any athlete is looking for to produce their very best, every single time.”
Masimo is also entering the general launch phase of a medical version of Masimo W1 for use in medical applications outside the U.S., with additional measurement capabilities such as spot-check electrocardiogram (ECG), atrial fibrillation (A-fib) detection, and more. Benefiting from Masimo’s expertise in hospital connectivity and hospital automation, the medical Masimo W1 will also be available for use in telehealth and telemonitoring applications via Masimo SafetyNet® and Personal SafetyNet for healthcare providers and payers, as well as individual use. For patients taking opioids to reduce pain or recovering at home after surgery or illness, as well as patients with chronic conditions (such as heart failure, COPD, or cancer), Masimo W1 will represent a convenient, reliable remote monitoring and telehealth solution enabling hospitals and clinicians to proactively keep track of their patients’ physiological status from afar, even as patients go about 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 data cloud, where it will be reviewed in near-real time by remote monitoring teams in centralized locations for signs of physiological decline or sudden changes, such as falls or spikes in heart rate.
In Saudi Arabia, where Masimo W1 is already approved for use in medical applications, Dr. Bakhsh, Head of the Heart Function Unit at Prince Sultan Cardiac Center, said, “We have begun using Masimo W1 with Masimo SafetyNet for remote patient monitoring of our chronic heart failure patients. The watch is very comfortable to wear, and the continuous Masimo measurements give us confidence to help keep our patients safe.”
Dr. Chaudhry, Chief Clinical Information Officer (CCIO) and Chief Information Officer (CIO) at Cambridge University Hospitals NHS Foundation Trust (CUH), said, “We have deployed Masimo Patient SafetyNet™ on our Intermediate Dependency Care Unit for continuous monitoring with pulse oximetry, and believe it has made a genuinely positive impact on the safety of our patients. My initial experience with Masimo W1, the Masimo Health app and Personal SafetyNet monitoring service has been very positive. As we go forward caring for patients, whether in the hospital or at home as part of the virtual wards we are setting up, 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 problems. The release of the Masimo W1 watch raises the bar on home wearables by providing pulse oximetry based on industry-leading SET® technology and continuous monitoring features in a wrist-worn device. By doing so, we can follow our health and fitness beyond the home, to any location that has 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 track other health parameters, both at rest and during activity.”
Joe Kiani, Founder and CEO of Masimo, said, “With over 30 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 cost of care.
