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周围组织产生的压力，能将液体挤出原处。

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

肺毛细血管内静水压升高的常见原因是心力衰竭。

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

肺毛细血管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。

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血压，两者都会导致肺毛细血管流体静压增高。

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细血管，可能是因为血管内静水压增高或血管内胶体渗透压降低。

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血压，是一种血液施加于血管壁上的力，可以看作一种外推力。

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细血管中漏出进入间隙。

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，毛细血管流体静压和血压相同，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细血管和间隙之间移动的3个主要因素：1.流体静压，2.胶体渗透压，3.毛细血管通透性。

The heart's entire purpose is to maintain that same kind of pressure gradient, by generating high hydrostatic pressure to pump blood out of the heart, while also creating low pressure to bring it back in.

心脏的全部目的是保持同样的压力梯度，通过产生高静水压将血液泵出心脏，同时也产生低压将血液带回来。
