Parameters

Cardiac Index (CI) Result

Formula

Cardiac Index (L/min/m²) = Cardiac Output (L/min) / Body Surface Area (m²)
BSA = √ [ (Height in cm × Weight in kg) / 3600 ]

Clinical Pearls

The definitive hemodynamic variable for hemodynamic subset classification in acute decompensated heart failure and myocardial infarction.

Limitations

Assumes BSA estimation accurately reflects metabolic tissue requirements; severe edema or ascites can skew BSA calculations.
