摘要

1型（低氧血症）RF的PaO2＜60 mmHg，PaCO2正常或低于正常。在这种类型中，气体交换在aveolo毛细管膜的水平上受到损害。I型RF的例子是致癌或非心源性肺水肿和严重肺炎。2型（高碳酸血症）RF的PaCO2＞50 mmHg。低氧血症是常见的，它是由于呼吸泵故障引起的。此外，呼吸衰竭根据其发作、病程和持续时间分为急性和慢性；慢性呼吸衰竭（CRF）之上的急性（ARF）[1]。

Hypoxemia and Respiratory Failure: Clinical Conditions and Pathophysiological Approaches

Type 1 (hypoxemic) RF has a PaO2 < 60 mmHg with normal or subnormal PaCO2. In this type, the gas exchange is impaired at the level of the aveolo-capillary membrane. Examples of type I RF are carcinogenic or non-cardiogenic pulmonary edema and severe pneumonia. Type 2 (hypercapnic) RF has a PaCO2 > 50 mmHg. Hypoxemia is common, and it is due to respiratory pump failure. Also, respiratory failure is classified according to its onset, course, and duration into acute and chronic; acute (ARF) on top of chronic respiratory failure (CRF) [1].
