Oxygen Delivery (DO2) Calculator
Calculates oxygen delivery (DO2) to tissues from cardiac output, haemoglobin, and oxygen saturation. Normal DO2: 950-1150 mL/min.
Score interpretation
Normal DO2
→ Adequate oxygen delivery; maintain current parameters
Reduced DO2
→ Optimise cardiac output, haemoglobin, and oxygenation
Critically low DO2
→ Immediate intervention: transfusion, inotropes, PEEP optimisation
Interpretation bands for the DO2. Apply clinical judgement and local guidance.
