There is growing evidence that airway complications are relatively common in critical care. Strategies have been suggested to decrease their incidence. ⋯ Our data suggest that several possible strategies for avoiding airway complications in ICU patients dependent on an artificial airway are poorly implemented. This may expose these patients to avoidable risk.

Disturbed breathing during sleep, with episodic upper airway obstruction, is frequent after major surgery. Ventilatory responses to hypercapnia and hypoxia during episodes of airway obstruction are difficult to investigate because the usual measure, that of ventilation, has been attenuated by the obstruction. We simulated the blood gas stimulus associated with obstruction to allow investigation of the responses. ⋯ After major surgery, ventilatory responses to hypercapnia and hypoxaemia associated with airway obstruction are small and do not improve after 6 weeks. With air breathing, arterial oxygen desaturation during simulated rebreathing is substantial.
