A medical start-up company based in Orange County, Calif, has introduced what it’s calling the world’s first wireless, continuous, fully disposable pulse oximeter. Produced by True Wearables, the Oxxiom, as it’s known, measures arterial oxygen saturation (SpO2), pulse rate, and perfusion index. The single-use device weighs 3.5 grams and provides more than 24 hours of continuous monitoring. Because it’s disposable, the monitor requires no sterilization and can reduce the risk of cross-contamination, the company says.

According to True Wearables, the underlying technology enables a range of up to 33 feet and allows patients free range to shower, use the restroom, wash their hands, sleep, or exercise. The device is “monitor agnostic” and compatible with mobile devices, tablets, laptops, and desktops. It requires no external batteries or battery chargers and its performance is unaffected by nail polish or ambient light. The device is expected to begin shipments in the second quarter of 2016.
