Pulsatile Flow Calculator

Patient & Circuit Inputs

Weight (kg)

Height (cm)

Hematocrit (%)

Hemoglobin (g/dL) Override if needed

Target MAP (mmHg)

Arterial Cannula Size (Fr)

Oxygenator Drop (mmHg) Default 30 mmHg

Measured EEP (mmHg, optional)

Lactate (mmol/L, optional)

BSA is calculated with the Haycock formula: 0.024265 × weight^0.5378 × height^0.3964
DO₂i target is 340 mL/min/m² for patients ≤10 kg, otherwise 280 mL/min/m²
Total flow is derived from the Fick principle: DO₂i × BSA / (Hb × 1.36 × 10)
EEP target is MAP + 15% (ratio ≥ 1.15)
