The oncotic pressure is higher in the pulmonary capillaries than in the interstitial fluid, so it opposes the hydrostatic pressure.

肺毛的胶体渗透压比肺间质胶体渗透压高，因此它与流体静压拮抗。

A common cause of increased hydrostatic pressure in the lung capillaries is heart failure.

肺毛内静水压升高的常见原因是心力衰竭。

Hydrostatic pressure refers to the pressure felt by fluid in a confined space, pushing the fluid out of that space.

流体静压是指流体在有限空间内对围组织产生的压力，能将液体挤出原处。

But it’s still higher than the hydrostatic pressure exerted by the interstitial fluid of the lungs - which is almost zero.

但它仍然高于肺组织间隙产生的流体静压（几乎为0）。

Common cardiogenic causes include left sided heart failure and hypertension, both of which lead to increased hydrostatic pressure in the pulmonary capillaries.

常见的心源性因素包括左心衰和高压，两者都会导致肺毛流体静压增高。

A transudative pleural effusion occurs when too much fluid starts to leave the capillaries either because of increased hydrostatic pressure or decreased oncotic pressure in the blood vessels.

漏出性胸腔积液发生于大量液体漏出毛，可能是因为内静水压增高或内胶体渗透压降低。

So, to be clear, if hydrostatic pressure was the only factor involved, a lot of fluid would be continuously leaking out of the pulmonary capillaries into the lung’s interstitial space.

因此请记住，如果流体静压是有关的唯一因素，许多体液便不断地从肺毛中漏出进入间隙。

In the interstitial space, it’s the same thing as the blood pressure in the pulmonary capillaries, and because the pulmonary circulation is a low pressure system, the hydrostatic pressure is pretty low.

在组织间隙，毛流体静压和压相同，且由于肺循环低压，其流体静压也较低。

To understand pulmonary edema, let’s first talk about the three main factors that determine how fluid moves between the capillaries and interstitial fluid, which are the hydrostatic pressure, oncotic pressure and capillary permeability.

为了解肺水肿，我们首先讲讲决定液体如何在毛和间隙之间移动的3个主要因素：1.流体静压，2.胶体渗透压，3.毛通透性。

Hydrostatic pressure is what we normally think of as blood pressure; it is the force that blood exerts on the walls of the blood vessel, and can be thought of as a pushing force.

静水压就像我们习惯上认为的压，是一种液施加于壁上的力，可以看作一种外推力。
