Document Summary
Intravascular space (fluid within the blood vessels) contains plasma: approximately 3l of average 6l of blood volume in adult males is made up of plasma, remaining 3l is made up of erythrocytes, leukocytes, and thrombocytes. Interstitial space contains the fluid that surrounds the cell and totals about. Ecf is referred to as third-space fluid shift or third spacing: early evidence of this is, a decrease in urine output despite adequate fluid intake. In a solution, cations and anions are equal in milliequivalents per liter: special techniques are required to measure electrolyte concentrations in the icf. 300ml daily: loss is much greater with increased respiratory rate or depth or in a dry climate. 6: decreased renal function, gi bleeding, dehydration, fever, sepsis. Increasing likelihood of fluid and electrolyte disturbances: dehydration is common in older adults due to, (cid:315)kidney mass, (cid:315)gfr, (cid:315)renal blood flow, (cid:315)ability to concentrate urine.
