Application Effect of Different Mechanical Ventilation Modes in the Treatment Process of Chest Compression Combined with Mechanical Ventilation
Objective:To explore the application effects of different mechanical ventilation modes in the treatment process of chest compression combined with mechanical ventilation.Method:From January 2022 to July 2023,100 patients with cardiac arrest using chest compression combined with mechanical ventilation who admitted to the Sixth Affiliated Hospital of South China University of Technology were selected as the study subjects,they were divided into the control group and the observation group using mechanical ventilation modes,with 50 patients in each group.The control group was given capacity control mode(V-A/C),while the observation group was given pressure support ventilation(PSV),the tidal volume,minute ventilation volume,oxygenation index,partial pressure of carbon dioxide(PCO2),oxygen partial pressure(PO2),coma index score,and rescue results of two groups were compared.Result:The tidal volume and minute ventilation volume of the observation group were higher than those of the control group,and the differences were statistically significant(P<0.05);the oxygenation index of the observation group after 0.5 h,1.0 h,2.0 h of ventilation were higher than those of the control group,and the differences were statistically significant(P<0.05);the PCO2 in the observation group after ventilation for 0.5 h,1.0 h and 2.0 h were lower than those in the control group,and PO2 were higher than those in the control group,the differences were statistically significant(P<0.05);after 24 h of ventilation,the scores of eye opening reaction and limb movement in the two groups increased,and those in the observation group were higher than the control group,the differences were statistically significant(P<0.05);the rescue success rate of the observation group after 2 h of ventilation was higher than that of the control group,and the difference was statistically significant(P<0.05).Conclusion:V-A/C and PSV can achieve good results in the treatment process of chest compression combined with mechanical ventilation,but V-A/C can increase tidal volume,minute ventilation,oxygenation index,PO2,coma index and rescue success rate.
