An adrenal hormone that increases sodium reabsorption & potassium secretion in the response to:
1. Hyponatremia
2. Hyperkalemia
3. Hypovolemia
4. Decreased C.O.
Normal PaO2?
80-100 mmHg
Define Osmolarity?
The physiochemical property of substances in a solution which determines osmosis.
Normal Serum Osmolarity: 275-300 mOsm/L
Total water % for newborns?
75%
State 3 primary determinants of Serum Osmolarity?
1. Sodium
2. Glucose
3. B.U.N.
Range of Normal Serum Osmolarity?
275-300mOsm/L
What is the action of Thiazide Diuretics?
1. Act by inhibiting tubular reabsorption of sodium, potassium, & chloride in the DISTAL TUBULE.
2. Additionally bicarbonate is reabsorbed causing metabolic alkalosis.
3. "Less potent than Loop Diuretics"
Define Millimole (mmol)?
1/1000 of a mole
*glucose is sometimes measured in mmols/L
