摘要 目的:探讨压力控制通气(PCV)与压力支持通气(PSV)两种通气模式实施肺复张策略治疗急性呼吸窘迫综合征(ARDS)对氧代谢指标的影响。方法:选择ARDS行机械通气的患者30例,随机实施PCV模式肺复张或PSV模式肺复张,其中PCV组设定F=10次/分,PC为15cmH2O,PEEP为30cmH2O,I:E=1:l;PSV组设定PS为15cmH2O,PEEP为30cmH2O;两组持续时间均为30s。记录复张前,后1分钟、5分钟、10分钟、20分钟、30分钟的呼吸频率和氧代谢指标的变化。结果:两种复张模式均使氧合明显改善,以PCV模式尤为明显。结论:采用PCV模式进行ARDS肺复张治疗对氧合的改善优于PSV模式。
