在某些情況下，脫機也許引起右室后負荷的顯著增加和右室擴大，並因此通過雙室舒張壓的相互依賴增加左室舒張末期壓。 -
Among the pathophysiological mechanisms, the sudden shift from a positie to a negatie intrathoracic pressure plays an important role since it results on the one hand in an increased pressure gradient for systemic enous return and in cardiac preload and on the other hand in a decreased pressure gradient for left - entricular ejection and an increase in left - entricular afterload
在諸多病理生理學機制中，胸內正壓向胸內負壓的突然轉換扮演了重要作用，一方面，是由於增加了體循環靜脈迴流的壓力梯度和心臟前負荷，另一方面，降低了左室射血的壓力梯度並增加了左室后負荷。
