Nettet28. okt. 2024 · The I:E ratio is the ratio of the duration of inspiratory and expiratory phases. It represents a compromise between ventilation and oxygenation. A normal I:E ratio is 1:2. More inspiratory time (I:E 1:1.5 or 1:1) increases mean airway pressure, and favours better oxygenation, at the cost of CO2 clearance.
