Document Summary
Pathophysiology- fluid and electrolyte imbalances: first, increased capillary hydrostatic pressure cause higher amount of fluid to leave capillary. If hydrostatic pressure continues to be high at venous end of capillary net fluid movement will be out of capillary: imbalance: increased capillary hydrostatic pressure result of: Just like edema- fluid trapped in interstitial -space not readily available for exchange with rest of ecf so called non-functional fluid. Intestines: might see third space loss of fluid inside lumen and wall of intestine if obstructed. Treatment of edema: what you do depends on why the edema occurred, correct the problem, control the underlying mechanism, ex related to malnutrition and albumin then make sure easy. Pathophysiology- fluid and electrolyte imbalances: osmoreceptors, located in hypothalamus keep track of osmolality or concentration of blood sodium is predominant osmotically active particle in blood, baroreceptors. In blood vessel wall and kidney and measure stretch i vessel wall produce by blood volume and blood pressure.
