Abstract：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 (P＜ 0.05).Conclusion It is recommended to use a separate mode for COPD patients instead of the combination of PSV and ATC.
