Design and implementation of the anesthesia machine monitoring system

An intellectual non-invasive anesthesia machine monitoring system is analyzed in this paper. The system consists of a data acquisition terminal, a communication module and a PC/104 monitoring platform. The data acquisition terminal detects the real-time parameters including tidal flow, airway pressure and oxygen concentration. These parameters will be transmitted to the monitoring platform through serial ports for records and analysis. In this way, the flow, pressure and concentration of the medicine can be controlled for the general anesthesia on the patient. With advantages of intuitive alarm signals, safe and reliable environment, and complete function, the system also realizes the expert diagnosis by XMLHttpRequest and Server-Sent Events technology. After repeated validation test, the system can work steadily and will have a wide application prospect in the market.
