Abstract:
Objective To carry out quality control testing of anesthesia ventilators to ensure the reliability and safety during their clinical use.Methods Totally 88 anesthesia ventilators used in some hospital underwent quality control testing in terms of tidal volume,peak airway pressure and positive end-expiratory pressure by using a gas flow analyzer according to JJF(E)61-2020 Calibration Specification of Anesthetic Machines,which included 31 ones,36 ones,12 ones and 9 ones respectively from brand A,B,C and D.The Kruskal-Wallis test was used to analyze the variability of the measured values and errors of the performance indicators between different brands of anesthesia ventilators,the chi-square test was applied to discussing the variability of the accuracy class of the performance indicators between different brands of anesthesia ventilators,and the Pearson correlation coefficient was adopted to investigate the correlation between the years of use and the absolute values of the relative errors of the performance indicators.Results The 88 anesthesia ventilators had the overall pass rate for quality control testing being 42.05%,of which,brand B had the highest pass rate(52.78%)and brand C had the lowest pass rate(8.33%).Brand B gained advantages in tidal volume when compared with brand A,C and D,with the differences being significant(P<0.05);brand A behaved the best in peak airway pressure and positive end-expiratory pressure when compared with brand B,C and D,with the differences being significant(P<0.05).Brand A had the highest proportion(63.08%)of distinction and credit in terms of the three performance indicators.The absolute value of the relative error in tidal volume was positively correlated with the years of use at the 3 measurement points for setting values of 400,600,and 800 mL respectively(P<0.05),and there was a significant correlation between the absolute value of the relative error and the years of use at a peak airway pressure setting of 10 cmH2O(1 cmH2O=98.07 Pa)(P<0.05).Conclusion Quality control testing of anesthesia ventilators contributes to finding the risks during their application,which can be an effective tool to ensure the safety of anesthesia ventilators used in medical institutions.[Chinese Medical Equipment Journal,2025,46(9):75-80]
