Preventing Hypoxemia With Manual Ventilation During Endotracheal Intubation (PreVent) Trial

Beginning after the administration of sedation/neuromuscular blockade, manual ventilation will be provided by bag-valve-mask until the initiation of laryngoscopy. In patients requiring more than one attempt at laryngoscopy, bag-valve-mask ventilation will resume between laryngoscopy attempts.

Between the administration of sedation/neuromuscular blockade and intubation, ventilation will not be provided unless the patient experiences an arterial oxygen saturation less than 90%. For patients who experience an oxygen saturation less than 90% after induction, bag-valve-mask ventilation may be provided.
