通气技术对面罩机械通气治疗慢阻肺呼吸衰竭疗效的影响

The influence of ventilation technology on the efficacy of mechanical ventilation with mask in the treatment of chronic obstructive pulmonary disease respiratory failure

目的:分析不同通气技术进行面罩机械通气治疗慢阻肺呼吸衰竭的效果。方法:2017年12月-2018年12月收治慢阻肺呼吸衰竭患者93例,通过面罩通气进行治疗,根据通气方式不同分为三组。A组使用S/T通气模式,患者佩戴橡胶面罩;B组使用S/T模式,患者佩戴塑料面罩;C组使用压力支持通气。比较三组患者血液动力学指标水平。结果:三组治疗前动脉血二氧化碳分压(PaCO2)和血氧分压(PaO2)水平比较,差异无统计学意义(P>0.05);三组治疗后动脉血PaCO2和血PaO2水平均有明显改善,各组比较差异无统计学意义(P>0.05)。结论:治疗慢阻肺呼吸衰竭,可根据患者实际情况选用合适通气技术,改善患者通气症状。

Objective:To explore the effect of different ventilation techniques of mechanical ventilation with mask in the treatment of chronic obstructive pulmonary disease respiratory failure.Methods:From December 2017 to December 2018,93 patients with chronic obstructive pulmonary disease respiratory failure were selected.They were treated with face mask ventilation.They were divided into three groups according to different ventilation methods.Group A used S/T ventilation mode,patients wore rubber mask;Group B used S/T mode,patients wore plastic masks;Group C used pressure support ventilation.We compared the levels of hemodynamic indexes in three groups.Results:Before treatment,there was no significant difference in PaCO2 and PaO2 among the three groups(P>0.05);After treatment,the levels of PaO2 and PaO2 in the three groups were significantly improved,there was no significant difference among groups(P>0.05).Conclusion:In the treatment of chronic obstructive pulmonary disease respiratory failure,appropriate ventilation technology can be selected according to the actual situation of patients to improve their ventilation symptoms.
