Vital sign monitoring apparatus

A vital sign monitoring apparatus includes a bar code list and a vital sign monitor. The bar code list includes determination bar codes and setting bar codes. The vital sign monitor includes a host computer and a bar code reader. The bar code reader reads at least one of the determination bar codes and the setting bar codes. The host computer includes a control unit, a transmission device and an intelligent memory device. The control unit is electrically connected with the bar code reader and a plurality of vital sign information input instruments. While reading the determination or setting bar code, the bar code reader generates an output signal. The intelligent memory device compares the output signal with the preset data to generate an action instruction. According to the action instruction, the control unit turns on/off the vital sign information input instruments or sets up the vital sign monitor.
