The PM-60 is a miniature, lightweight device that can accurately check and continuously monitor SpO2 and pulse rate. The user sets the functions and performance according to the selected operating mode. The functions for checking basic vital signs include automatic patient ID assignment, alarm signal suppression status, and automatic standby mode as well as power-off functions. For long-term monitoring, the continuous mode allows manual entry of unique patient IDs, alarm signal management, and data formatting.
