-
Can be caused by a loss of both water and solutes
(electrolytes and nonelectrolytes) in ECF
Fluid volume deficit
-
A.K.A. Hypovolemia, dehydration, isotonic fluid loss
Fluid volume deficit
-
Results from loss of body fluids or decreased fluid
intake; Most at risk: young, old, & ill
Fluid volume deficit
-
A.K.A “Third-spacing"
Third Space Fluid Shift
-
Fluid shifts of body fluids into transcellular
compartments (not into intracellular space); example Pleural, peritoneal, or pericardial space,
Joint cavities, bowel, interstitial space
Third-Space Fluid shift
-
-
Peritoneal
around the abdomen
-
pericardial space
around the heart
-
Once trapped in these spaces, the fluid does not easily move
Third-Space Fluid shift
-
Results in ECF volume deficit; Caused by disruption in colloid osmotic pressure, increased fluid volume, hyponatremia, severe burns, sepsis
Third-Space Fluid shift
-
hyponatremia
severly low sodium
-
shock, and increase blood pressure
hypovolemia
-
Decreased body weight does not occur & fluid loss
can’t be measured, May have edema & signs of hypovolemia
Third-Space Fluid shift
