机械通气对急性肺损伤(ALI)患者来说是挽救其生命的重要措施,研究者进行过很多研究以寻找更安全有效的通气方式和策略,各中心的随机试验结果并不相同。直至1998年一个单中心试验证实采用“肺保护策略”,包括较低的潮气量、压力通气模式和分析压力 容量曲线(P Vcurve)来选择适当 Mechanical ventilation is an important measure to save lives in patients with acute lung injury (ALI). Researchers have conducted many studies to find safer and more effective ventilation and strategies. Results from randomized trials in different centers are not the same. Until 1998, a single-center trial confirmed the use of “lung protection strategies”, including lower tidal volume, plenum mode and analysis of the pressure capacity curve (P Vcurve) to select the appropriate
