Pressure differentials govern fluid movement across physiologic semi-permeable membranes, and two of these forces are hydrostatic/hydraulic pressure and osmotic pressure. The third factor is the permeability of the capillary membranes. There will be an escape of water and solute into the interstitial space resulting in interstitial edema whenever the hydrostatic pressure is much higher than the osmotic pressure inside the intravascular space. Edema also occurs when there is capillary leakage due to impaired membrane integrity such as in burns or anaphylaxis.

Hydrostatic pressure in blood vessels is caused by the weight of the blood above it in the vessels. Hydrostatic pressure is the pressure exerted by a fluid at a given point, due to the weight of the fluid above it. Blood is a fluid, so blood has a hydrostatic pressure. Increased elevation increases the amount of hydrostatic pressure. For example, the veins and capillaries in our feet have about 100 mm Hg more pressure inside than those at heart level. In an upraised hand, the hydrostatic pressure is about 50 mm Hg less than at heart level. Hydrostatic pressure is not the only pressure that exists in a blood vessel We must consider also the hydraulic pressure caused by the pumping of the heart Hydraulic pressure is the pressure that results from pushing a liquid through a pipe or other channel. Osmotic pressure is also present. It depends on the relative concentrations of solutes on either side of the vessel walls. So blood pressure has hydrostatic, hydraulic, and osmotic components.

Pulmonary capillary hydrostatic pressure is the pressure which forces fluid out of the pulmonary capillaries into the interstitium, causing pulmonary oedema. It can be measured by analysis of a transient pressure change which occurs after an acute PA occlusion. Measuring this variable could be useful in the diagnosis of non-cardiogenic pulmonary oedema and to guide fluid resuscitation.
