呼吸系统准静态压力-容积(pressure-volume,P-V)曲线描述肺和胸壁在吸气和呼气期间机械力学特征。在自主呼吸个体中,膈肌和胸壁共同形成机械泵推动气体吸入和呼出双肺完成氧交换和排
The respiratory quasi-static pressure-volume (P-V) curve describes the mechanical characteristics of the lung and chest wall during inspiration and expiration. In spontaneously breathing individuals, the diaphragm and chest wall together form a mechanical pump that pushes gas into and out of the lungs to complete the oxygen exchange and exhaust
