Lab Data for Fluid, Electrolyte and Acid-Base Imbalances

Home Get App Take Quiz Create Fluid and Electrolyte imbalances - what electrolytes are involved? alterations in sodium potassium magnesium calcium phosphates chloride bicarbonate (venous carbon dioxide concentrations) Fluid and Electrolyte imbalances - related to loss of ECF or gain of solutes increase in hematocrit increased BUN increased sodium increased osmolality in serum Fluid and Electrolyte imbalance - related to gain of ECF or loss of solutes decrease in hematocrit decreased BUN decreased sodium decreased osmolality in serum Metabolic Alkalosis - lab values pH > 7.45 PaCO2 normal or > 45 mm Hg if lungs are compensating PaO2 normal O2 saturations (SO2) normal HCO-3 > 26 mEq/L Ionized calcium < 4.5 mg/dL K+ < 3.5 mEq/L Metabolic Acidosis - lab values pH < 7.35 PaCO2 normal or < 35 mm Hg if lungs are compensating PaO2 normal O2 saturation normal HCO3- < 22 mEq/L K+ > 5 mEq/L Respiratory Alkalosis - lab values pH > 7.45 PaCO2 < 35 mm Hg PaO2 normal O2 saturation normal HCO-3 < 22 mEq/L Ionized calcium < 4.5 mg/dL K+ < 3.5 mEq/L Respiratory Acidosis - lab values pH < 7.35 PaCO2 > 45 mm Hg PaO2 normal or < 80 mm Hg, depending on cause of acidosis SaO2 normal or < 95%, depending on cause of acidosis HCO3- normal if early respiratory acidosis or > 26 mEq/L if kidneys are compensating K+ > 5 mEq/L
