WebAn increased capillary hydrostatic pressure and vascular permeability are, in contrast, potent causes of edema. Colloid oncotic pressure (COP) can be measured; values in normal animals are 20 to 25 mm Hg. Values of 15 to 20 mm Hg are common in critically ill patients but are not thought to be of important concern. WebDecreased plasma oncotic pressure Increased capillary permeability Obstruction of the lymphatic system As fluid shifts into the interstitial space, intravascular volume is depleted. Intravascular volume depletion activates the renin-angiotensin-aldosterone- vasopressin (ADH) system, resulting in renal sodium retention.

WebWhat causes increased interstitial oncotic pressure? The more permeable the capillary barrier is to proteins, the higher the interstitial oncotic pressure. This pressure is also determined by the amount of fluid filtration into the interstitium.

WebAug 16, 2024 · While capillary hydrostatic pressure favors transcapillary fluid movement into the interstitium, the colloid oncotic pressure across the capillary favors the retention of fluid within the vessel ( figure 1 ). Under normal circumstances, these competing forces result in a small net movement of fluid into the interstitium.
