肺脏的换气一氧合功能必须由肺内正常的通气—灌流关系来保证。在某些情况下,肺的血流量及血液分布会发生改变,以保障肺内通气较好的部位获得较充分的血液。由于很多急性呼吸衰竭原因不明(总称为呼吸窘迫综合征),严重危胁着病员的生命,故有必要对肺脏的基本生理进行深入的研究。已知的影响肺血流(包括血流量及其分
Ventilation in the lungs Aerobic oxygenation must be ensured by the normal ventilation-perfusion relationship in the lungs. In some cases, the blood flow and blood distribution in the lungs will change to ensure adequate ventilation in the well-ventilated area of the lungs. Because many of the causes of acute respiratory failure are unknown (commonly referred to as respiratory distress syndrome), which seriously threatens the lives of patients, it is necessary to conduct an in-depth study of the basic physiology of the lungs. Known effects on pulmonary blood flow (including blood flow and its score
