为什么俯卧位对呼吸窘迫综合征（ＡＲＤＳ）病人有利ＡＲＤＳ和肺炎等肺疾病可致通气灌流比例（Ｖ／Ｑ）失调，部分原因是由于低垂的肺部浸润和不张，即某些肺区通气好但灌注不足，而另一些区域灌注好但通气不足。由仰卧转为俯卧，肺内体液再分布有助于肺膨胀，减轻肺后部... Why prone prone position in patients with respiratory distress syndrome (ARDS) ARDS and pneumonia and other lung diseases can cause ventilatory perfusion (V / Q) imbalance, in part because of drooping lung infiltration and atelectasis, that is, some lung areas Ventilation is good but insufficient perfusion, while others are well perforated but not adequately ventilated. From supine to prone, redistribution of fluid in the lung contributes to lung expansion, reducing the posterior lung ...
