急性肺功能衰竭综合征(简称肺衰)习称“休克肺”,近年来称为“急性吸吸窘迫综合征”。国内有关这方面的介绍和报导不多。临床上,该综合征的发生率是较高的。Bredenberg(1974)认为任何原因引起的危重病人都有可能并发此综合征。本文从三方面重点探讨:1.肺循环分流量升高;2.通气-血流比值异常;3.V_A/Q与肺衰的分型。 Acute lung failure syndrome (referred to as pulmonary failure) Xi said “shock lung”, in recent years as “acute suction distress syndrome.” Domestic introduction and coverage in this area is limited. Clinically, the incidence of the syndrome is higher. Bredenberg (1974) that any cause of critically ill patients are likely to complicated by the syndrome. This article focuses on three aspects: 1. Pulmonary circulation shunt increased; 2. Ventilation - abnormal blood flow ratio; 3.V_A / Q and pulmonary failure type.
