摘要
目的观察压力支持通气模式(pressure support ventilation,PSV)联合自动插管补偿(automatic tube compensation,ATC)与单纯PSV模式对慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)患者呼吸力学的影响。方法 21例COPD患者按随机顺序分别采用PSV+ATC模式和PSV模式进行治疗,比较两种模式对潮气量、无效呼吸次数、流速-容量(Flow-Volume,F-V)曲线等呼吸力学参数的影响。结果与PSV模式相比,PSV+ATC模式时COPD患者的潮气量显著增加,高潮气量报警次数和无效呼吸次数明显增多,F-V曲线的初始吸气速度显著增大,组间比较差异具有统计学意义(P<0.05)。结论对于COPD患者,不推荐PSV与ATC联合使用,建议两种模式分别单独使用。
Objective To investigate the effects of pressure support ventilation(PSV)combined with automatic tube compensation(ATC)on respiratory mechanics in patients with chronic obstructive pulmonary disease(COPD).Methods Twenty-one COPD patients were allocated into PSV+ATC group and PSV group in random order based on different treatment modes.The respiratory parameters including tidal volume,ineffective inspiratory times and flow-volume(F-V)curves,were compared.Results Compared with PSV+ATC modes,tidal volume,high tide alarm and ineffective inspiratory times,and initial inspiratory speed of F-V curves of COPD patients all increased in PSV+ATC mode(P0.05).Conclusion It is recommended to use a separate mode for COPD patients instead of the combination of PSV and ATC.
