Poor gas exchange during initial phase of ventilation

• Increase FIO2 to 1.0 and start manual ventilation.

• Check endotracheal tube is correctly positioned and both lungs are being inflated. Consider tube replacement, intratracheal obstruction or pneumothorax.

• Check ventilator circuit is both intact and patent and ventilator is functioning correctly. Check ventilator settings including FIO2, PEEP, I:E ratio, set tidal volume, respiratory rate and/or pressure control. Check 'pressure limit' settings as these may be set too low, causing the ventilator to time-cycle prematurely.
