Presentation Transcript

  1. Body fluid Regulation & abnormalities Lec 10

  2. Distribution of total body water

  3. Factors affecting total body water: • 1. gender • 2. age • 3. Total body fat

  4. Body fluid compartments; • 1. intracellular (2/3) • 2. Extracellular (1/3); • A. Interstitial fluid • B. Plasma

  5. Daily input & output

  6. Regulation of fluid exchange between body Compartments ICF & ECF; Determined by osmotic effect of solutes across the cell membrane. Plasma & interstitial spaces Colloid osmotic force & hydrostatic force across the capillary membrane.

  7. Why its important to maintain body fluid in critically ill patients? • 1. Dehydration will lead to hypovolemia and renal impairment. • 2. Over-hydration will lead to pulmonary edema and heart failure.
