The other 4 Ps are less common, as pulselessness appears only when the compartment pressure is so high that it makes the arteries collapse.

另外“4P”比较少见，无脉仅出现在腔室内压力过高致使动脉塌陷时。

These proteins draw more water from the capillaries and we get a vicious cycle of increased compartment pressure, tissue hypoxia, edema, followed by cellular death and even more pressure.

这些蛋白质会从毛细血管吸收更多水分，形成恶性循环，使腔室内压不断增高，组织缺氧、水肿，导致细胞死亡，腔室内压力更高。
