慢性阻塞性肺疾病 (ＣＯＰＤ)急性加重期致Ⅱ型呼吸衰竭(呼衰 )患者行机械通气时常发生气道压高并存在内源性呼吸末正压 (ＰＥＥＰｉ) ,撤机有时较困难。指令频率通气 (ＭＲＶ)是一种自主呼吸条件下的带强制呼吸频率的压力支持通气模式 ,我们的研究观察了ＭＲＶ模式对 13例Ⅱ型
Patients with type II respiratory failure (COPD) exacerbation during chronic exacerbation of chronic obstructive pulmonary disease (COPD) often have an increased airway pressure and endogenous positive end-expiratory pressure (PEEPi) during mechanical ventilation, and the weaning is sometimes more difficult. MRV is a forced ventilatory supportive breathing mode with spontaneous breathing. Our study examined the effect of MRV on type II
