Tip 38: oxygenation index

The oxygenation index (OI) is useful for evaluating the degree of respiratory support a baby needs.

OI = (mean airway pressure x % O2) / mmHg paO2

If using kPa as units, divide the answer above by 7.5 (as 1mmHg = 7.5 kPa).

OI >25 is often an indication for ECMO referral in appropriate babies.
