Masimo has entered the increasingly competitive and crowded health watch market with the launch of Masimo W1. The first-of-its-kind wrist-worn wearable collects health data by the second, taking 86,400 daily measurements including oxygen saturation (SpO2) levels, pulse rate, respiration rate, and more, and, in a limited market release, hydration index.
Paired via secure Bluetooth to the Masimo Health smartphone app, Masimo W1 provides continuous health data, unlocking meaningful, actionable insights, with high accuracy. 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 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.
"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," Masimo Founder and CEO Joe Kiani said. "The SET technology we invented for hospitals transformed patient monitoring, saved lives, and reduced the cost of care. Based on the feedback we have received from those who have tested Masimo W1 during the limited market release phase, we believe this watch will improve lives."
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 a hydration baseline, helping its wearer understand his/her hydration level, which not only affects athletic performance and fatigue, but can carry significant risks, especially for users with conditions like congestive heart failure. Masimo W1 with Hydration Index represents a breakthrough solution to better understanding and management of hydration.
"Masimo W1 is a gamechanger. As a professional triathlete, I’m always looking to optimize my performance in every way possible," Olympic silver medalist Morgan Pearson commented. "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."
"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," Olympic silver medalist Dotsie Bausch added. "Masimo delivers 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 United States, 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 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. 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."
In the United States, Masimo W1 for use in medical applications is pending U.S. Food and Drug Administration clearance.
