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 help people gain insight into hydration. 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 is designed to help you identify your hydration baseline, helping you understand your hydration level, which not only affects athletic performance, but can also support healthier lifestyle decisions. Whether you’re an elite athlete, a vocalist, a health-focused individual, or just keen to gain more insight into your body’s physiological status, Masimo W1 with Hydration Index represents a breakthrough solution to better understand and manage hydration health.

Tommy Haas, Olympic silver medalist and professional tennis player, said, “I have wanted to know the level of my hydration since I began competing, but always had to guess about it. Masimo W1 with Hydration Index finally makes this possible.”

Nick Mayhugh, World Record holder and three-time Paralympic champion, added, “As a professional athlete who trains six days a week and ten hours a day, I need to know my hydration levels at all times. Masimo’s Hydration Index technology will provide athletes of all levels the opportunity to maximize their training and recovery programs, leading to optimal performance.”
