WebDec 9, 2024 · The cardiac index is the relationship, or proportion, of cardiac output to body surface area. It is measured in liters per minute per square meter {eq}(L/min/m^2) {/eq}. WebThis might make more sense if we are reminded of the relationship between pulmonary vascular resistance and pressure: pulmonary vascular resistance is proportional to pulmonary arterial pressure and inversely proportional to cardiac output. Alternatively, Pulmonary vascular resistance ~ pulmonary arterial pressure / cardiac output.

WebVessel resistance (R) is directly proportional to the length (L) of the vessel and the viscosity (η) of the blood, and inversely proportional to the radius to the fourth power (r 4) or diameter to the fourth power (D 4).Diameter can be substituted for radius because diameter and radius are directly proportionate to each other (D = 2r; therefore D ∝ r).
