A medical cloud system with an automatically checking and feeding back self-status function utilizes a database to receive and integrate a physiological information, an electronic physiological monitoring device intrinsic information, an electronic physiological monitoring device status information, an electronic physiological monitoring device error code or a miss operation information from an electronic physiological monitoring device through a smart transmitting unit. The database can notify user or manager of the electronic physiological monitoring device of arising of the electronic physiological monitoring device status information, the electronic physiological monitoring device error code or the miss operation information, and confirm the system status. The medical cloud system with an automatically checking and feeding back self-status function has the function of monitoring and long-distance transmitting to ensure the monitoring quality and prevent the serious consequence caused by fault or error of the electronic physiological monitoring device.
