Analysis of the Causes and Countermeasures of Abnormal PETCO2 Monitoring in ARDS Patients Undergoing Mechanical Ventilation Using a Multifunctional Monitor
Objective:To explore the causes of abnormal monitoring of end-expiratory carbon dioxide partial pressure(PETCO2)in emergency acute respiratory distress syndrome(ARDS)patients undergoing mechanical ventilation and analyze countermeasures.Methods:80 emergency ARDS mechanical ventilation patients admitted to our hospital from September 2020 to September 2022 were selected.All admitted patients underwent PETCO2 monitoring,and the abnormal situation of PETCO2 monitoring in all patients was recorded and the specific reasons were recorded.The reasons for the abnormal situation were analyzed.Results:A total of 80 emergency ARDS patients undergoing mechanical ventilation were monitored 1254 times in this study,with 248 abnormal occurrences of PETCO2 recorded.The incidence of PETCO2 was 19.78%.The incidence of improper placement of tracheal catheters was 9.27%,the incidence of insufficient ventilation was 10.48%,the incidence of respiratory circuit leakage was 28.63%,the incidence of secretion obstruction was 14.11%,the incidence of lung irrigation was 6.45%,the incidence of airbag leakage was 14.11%,the incidence of over ventilation was 12.50%,and the incidence of mechanical failure was 4.44%.Conclusion:Continuous detection of patients through PETCO2 monitoring can be carried out by combining PETCO2 abnormal display with specific patient conditions and other test data for joint analysis,timely and effective detection of adverse conditions in ventilation,circulation,or metabolism of patients,thus taking timely and effective measures to improve patient treatment rate and prognosis.
