Discussion on the principle of anaesthetic machine and measurement method for output concentration of anesthesia gas

Objective： To study the principle of the anaesthetic machine and measurment methods for output concentration of anaesthetic gas. Methods： Based on introduction of the principles of anaesthetic machine and its evaporator tank, it analyzed some impact factors that influence the concentration value of anaesthetic gas output. Thereafter, the measurement method of output concentration of anaesthetic gas will be preliminarily studied and discussed according to some relative standards. Results： The measurment methods for output concentration of anaesthetic gas are established, including test environment, test equipment and its connection, test items and methods. Conclusion： The quality control of anaesthetic gas output will contribute to improve the medical quality and reduce the medical risk. The article will be helpful to relevant clinicians, clinical nurses and mecical engineers
