Let's consider the implications of the transpulmonary pressure.

我们思考一下肺间压的作用。

Specifically, the transpulmonary pressure and thus vacuum effect is lost causing the lungs to collapse.

具体而言，肺间压和真空环境消失，导致肺部塌陷。

If not for this transpulmonary pressure, the lungs would collapse and we could not breathe.

如果没有肺间压，肺将塌陷，这样，我们将无法呼吸。

Transpulmonary pressure is the difference between the intrapleural pressure (outside of the lungs) and the intrapulmonary pressure (that's inside the lungs).

肺间压（Transpulmonary pressure）指胸膜内压（肺外）和肺内压（肺内）之间的差值。

Let's consider an unfortunate scenario to help us understand the importance of the transpulmonary pressure.

我们通过一种糟糕的场景来说明肺间压的重要性。

This pressure gradient between the lungs and the pleural cavity is referred to as transpulmonary pressure and creates a vacuum effect that is necessary to keep the lungs expanded at all times.

肺和胸膜腔之间的这种压力梯度被称为经肺压，产生真空效应，这是保持肺始终扩张所必需的。
