Hypovolemia is sodium & water excess, occurs with heart failure. Heart failure reduces renal blood flow and causes retention of sodium & water.
What would be the result of low colloid osmotic pressure?
Less water would be pulled into the blood vessels from the interstitial spaces.
What would increased capillary permeability cause?
Damage to blood vessels causes proteins to leak into the interstitial space, the result is edema since the protein in the interstitial space attracts water.
What would an increase in hydrostatic pressure cause?
An increase in capillary hydrostatic pressure will cause fluid & solutes to be forced into interstitial space or prevent colloid osmotic pressure from pulling water in.
What would happen to the blood volume if more water stayed in the interstitial space?
More water in the interstitial spaces would create a lower blood volume.
What are clinical indications of fluid volume deficiency?
Indications of fluid volume deficiency may include decreased urine, output, drop in systolic BP, weak rapid pulse, dry mucous membranes, last stages include cold, clammy skin, olguria, stupor & coma.
How would colloid osmotic pressure decrease?
A decrease in serum protein (albumin), as in malnutrition, burns or liver damage result in low colloid osmotic pressure.
What is hypovolemia?
Hypovolemia is due to a loss of both water & electrolytes, especially sodium.
What is colloid osmotic pressure?
Colloid osmotic pressure is the pulling force of albumin (protein) in the intravascular space.
What are the signs & symptoms of hypervolemia?
Weight gain, peripheral edema, distended neck & peripheral veins, bounding full pulse, polyuria, pulmonary edema, moist rales. Serum sodium levels may be normal or decreased due to dilution.
