Deranged physiology shunt equation
WebThe shunt equation (equation 15.3) describes the proportion of total perfusion that is passing through the shunt. This is the equation worth remembering: the portion of blood going through the shunt is the difference between the capillary and arterial O 2 concentrations, divided by the difference between the capillary and venous oxygen ... WebOct 24, 2024 · Anion gap formula: Na + – (Cl – + HCO 3–) The anion gap (AG) is a derived variable primarily used for the evaluation of metabolic acidosis to determine the presence of unmeasured anions (e.g. albumin is the main unmeasured anion). The normal anion gap varies with different assays but is typically between 4 to 12 mmol/L.
