Note: To operate the OxyKnight® Watch Lite, you must download the free OxyKnight® Watch Application. OxyKnight® Watch Lite cannot be used as a standalone device.  The OxyKnight® Watch Lite is a lightweight and compact wrist oximeter designed for continuous monitoring of children's oxygen saturation levels at home. Designed specifically for children, the soft, flexible fingertip cup and adjustable wrist strap are comfortable to wear for long periods of time. This reduces the need to make adjustments to the device's position or settings during the night. This device offers the same High-Resolution Pulse Oximetry (HRPO) function – tracking and monitoring oxygen levels (SpO2), pulse rate, and sleep cycles – as the OxyKnight® Watch. Compatibility with the existing OxyKnight® Watch mobile app provides reporting and monitoring functions, app-based data storage, and the app-based alarm that alerts to any drops in oxygen saturation levels. The OxyKnight® Watch Lite is a dependable, affordable, and accurate overnight oxygen monitoring solution – making it essential for monitoring children with chronic conditions like sleep apnea, sleep-related hypoxia, COPD, and other respiratory issues. OxyKnight® Watch Lite is also compatible with AsthmaGo®, our Asthma Management Solution. Compatible devices are sold separately.
