Reliability Verification of End-of-life Carbon Dioxide Concentration in a Multi-parameter Monitor Based on RRS-1 Metrological Verification
The RRS-1 respiratory rhythm generator(RRS-1)is a device used to detect the accuracy of the respiratory rate of the end expiratory carbon dioxide monitoring part of a multifunction patient monitoring instruments or a separate end expiratory carbon dioxide monitor.It can also be used in conjunction with different concentrations of carbon dioxide standard gases to detect the accuracy of the measured instrument's carbon dioxide concentration.Multifunction patient monitoring instruments are the most commonly used monitoring equipment in clinical applications,and monitors used in operating rooms or ICUs often have carbon dioxide monitoring modules.This article uses RRS-1 to verify the end of breath carbon dioxide concentration of multi parameter monitors according to the JJG 1163-2019"Verification Regulations of Multifunction Patient Monitoring Instruments",in order to verify its reliability.
