Apnoeic oxygenation during laryngoscopy has been emphasised in recent recommendations for airway management. We aimed to compare the effect of nasal oxygen supplementation on time for pulse oximeter oxygen saturation (SpO 2 ) to fall from 100% to 92% (desaturation safety time), to assess the arterial oxygen partial pressures (PaO 2 ) with and without nasal oxygen supplementation and the time for SpO 2 to recover from 92% to 100% after initiation of ventilation.
