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.

肺水肿，我们首先讲讲决定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。

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，许多体便不断地从肺毛细血管中漏出进入间隙。

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0）。

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，且由于肺循环压，其流体静压。

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。

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。

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，能将体挤出原处。

" They tell the farmers exactly how they want the chickens raised, what temperature to keep the houses at, the static pressure to keep the houses at, the wind speed." " Who's this? " Oh, this is Tyler Whitley.

“他们确切地告诉农民他们想要如何饲养鸡，将鸡舍保持在什么温度，保持鸡舍的静压，风速。” “这是谁？”哦，这是泰勒惠特利。
