Enough with fluid, let’s move on to electrolytes!
First, I’m just going to give you a list of common electrolytes and their normal values.
Sodium (Na+) 135-145 mEq/L
Potassium (K+) 3.5-5.0 mEq/L
Calcium (Ca++) 9-11 mg/dL
Magnesium (Mg++) 1.5-2.5 mEq/L
Phosphate (PO4-) 1.2-3 mEq/L
Chloride (Cl-) 100-110 mEq/L
Albumin 3.4-4.8 g/dL
As we discussed earlier, electrolytes can affect the amount of fluid in the intracellular and extracellular compartments. Each compartment contains different amounts of each electrolyte, normally. Let’s go over those.
Intracellular: potassium, magnesium, phosphate, and a large amount of protein (albumin).
Extracellular (intravascular): sodium, a small amount of potassium and magnesium, chloride, bicarbonate, and a small amount of protein.
