机械能是指呼吸机为实现肺通气而传递给呼吸系统的能量,能量大小可以通过P-V环的曲线下面积得到,也可以将能量表示为包含呼吸机参数和肺部特性的函数。近年来,有研究者认为机械能或许是一个从总体上评估呼吸机相关肺损伤的良好指标,进而用于指导最佳的机械通气策略。

Mechanical power of ventilation is defined as the energy delivered to respiratory system by ventilator. The value of power can be calculated by area under curve (AUC) of pressure-volume loop. Mechanical power can also be expressed as a function of ventilatory parameters and pulmonary characteristics. Recently, studies have suggested that mechanical power may be used as a good indicator to evaluate the ventilator-induced lung injury, which can further guide the optimal strategy of mechanical ventilation.
