Health monitor X1 is primarily designed for monitoring bedridden vital signs and early detection of symptoms related to cardiopulmonary chronic diseases and sleep apnea. Due to its non-intrusive and operation-free features, X1 is particularly suitable for long-term health monitoring of the elderly, children, and individuals with cardiovascular and cerebrovascular chronic conditions. X1 can non-invasively detect user's sleep duration, deep sleep ratio, heart rate, respiratory rate, apnea episodes, and bed departure status, thereby providing predictions on the user's cardiopulmonary and sleep health.
