Application Effect of Different Mechanical Ventilation Modes in the Treatment Process of Chest Compression Combined with Mechanical Ventilation
目的:探究不同机械通气模式在胸外按压联合机械通气救治过程中的应用效果.方法:选择 2022 年 1 月—2023 年 7 月华南理工大学附属第六医院收治的 100 例心搏骤停应用胸外按压联合机械通气救治患者作为研究对象,按照机械通气模式将其分为对照组和观察组,各 50 例.对照组采用容量控制模式(capacity control mode,V-A/C),观察组压力支持通气(pressure support ventilation,PSV),比较两组潮气量、分钟通气量、氧合指数、二氧化碳分压(partial pressure of carbon dioxide,PCO2)、氧分压(oxygen partial pressure,PO2)、昏迷指数评分、抢救结果.结果:观察组潮气量、分钟通气量高于对照组,差异有统计学意义(P<0.05);观察组通气 0.5 h、1.0 h、2.0 h后氧合指数高于对照组,差异有统计学意义(P<0.05);观察组通气 0.5 h、1.0 h、2.0 h后PCO2 低于对照组,PO2 高于对照组,差异有统计学意义(P<0.05);通气 24 h后,两组睁眼反应、肢体运动评分提高,且观察组高于对照组,差异有统计学意义(P<0.05);观察组通气 2 h后抢救成功率高于对照组,差异有统计学意义(P<0.05).结论:V-A/C、PSV在胸外按压联合机械通气救治过程中均能获得良好的效果,但V-A/C可提高潮气量、分钟通气量、氧合指数、PO2、昏迷指数、抢救成功率.
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.
