Modern anesthesia machines have safety monitoring systems. The system includes: oxygen deficiency alarm, oxygen deficiency/interruption stop gas trap, capacity and concentration monitoring and fault alarms. The monitoring part mainly includes: inhaled oxygen concentration, exhaled tidal volume, airway pressure, minute ventilation, end-tidal CO2 concentration, anesthetic gas concentration. The use of microcomputers to process and display data, together with an alarm device system, in particular, respiratory, circulatory, neurological, and muscular monitoring functions can be achieved, greatly improving the quality of clinical anesthesia and patient safety, and improving the success rate of surgery. .

The residual gas removal system collects the excess residual gas in the anesthesia machine and exhaust gas exhaled by the patient and discharges it through the pipeline to the operating room to avoid air pollution in the operating room. Mainly include exhaust gas collection and discharge devices consisting of: regulating valves, discharge valves, vacuum generators, pipelines and connectors, etc.

Inhalation anesthesia is to send anesthetic (agent) through the mechanical circuit into the patient's alveoli, forming an anesthetic gas partial pressure, diffuse to the blood, the direct inhibition of the central nervous system, resulting in the effect of general anesthesia.

Air anesthesia machines are semi-open anesthesia devices. It mainly consists of a liquid tank, an ether adjustment switch, a folding bellows, and a suction and exhalation one-way flap and bellows. As shown in Figure 2-1-1. The device is lightweight and suitable for direct use of air and oxygen as a carrier gas. It can assist breathing and control breathing to meet various surgical requirements.
