Summary
A WFPICCS webinar explaining V/Q mismatch, shunt and dead space as mechanisms of hypoxaemia in critically ill children, with guidance on interpreting blood gases and oxygenation indices such as PF and SF ratios, oxygenation index and A-a gradient. It links this physiology to bedside management including oxygen therapy, PEEP optimisation, recruitment and escalation for refractory respiratory failure.
