肺水肿系泛指过多的液体由肺血管内转移到肺间质及肺泡所引起的综合征。其早期表现为间质水肿,病情进一步发展,肺泡内的气体被液体所置换,则形成肺泡水肿。肺水肿是临床常见的综合征。可发生于多种疾病,往往以急性呼吸衰竭的形式出现,如能早期发现,及时救治,预后较好。肺水肿在临床上一般分为心源性肺水肿和非心源性肺水肿两大类。现就有关主要问题作一介绍。
Pulmonary edema refers to excessive fluid transfer from the pulmonary blood vessels to the lung interstitial and alveolar caused by the syndrome. The early manifestation of interstitial edema, the further development of the disease, the alveolar gas replaced by the liquid, the formation of alveolar edema. Pulmonary edema is a common clinical syndrome. Can occur in a variety of diseases, often in the form of acute respiratory failure, such as early detection, timely treatment, the prognosis is good. Pulmonary edema is generally divided into two major categories of cardiogenic pulmonary edema and non-cardiogenic pulmonary edema in clinical practice. I will give a briefing on the main issues.
