Do you know anything about remote health management? A friend got this service for his parents.

Remote health management means that users can set up high-tech Bluetooth devices such as Bluetooth electronic sphygmomanometer and Bluetooth electronic oximeter to measure blood pressure, ECG, pulse and blood oxygen. These measurement results representing vital signs are displayed on smartphones above Android 2.0, uploaded to the background system of Nuoan Health Cloud through Unicom CDMA network, and automatically returned to the user's mobile phone for health parameter analysis, health advice and danger signal reminder after background processing.
