Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Preoxygenation With Non-Invasive Positive Pressure Ventilation Group | Patients assigned to preoxygenation with non-invasive positive pressure ventilation will receive non-invasive mechanical ventilation via a tight-fitting mask from the initiation of preoxygenation until the initiation of laryngoscopy. Trial protocol will not dictate the brand or type of mechanical ventilator that will be used to deliver non-invasive ventilation.~Preoxygenation with Non-Invasive Positive Pressure Ventilation: The delivery of oxygen and ventilation by non-invasive mechanical ventilation via a tight-fitting mask from the initiation of preoxygenation until the initiation of laryngoscopy. Trial protocol will not dictate the brand or type of mechanical ventilator that will be used to deliver non-invasive ventilation. | 534 | 645 | OG000 |
| Group 2 | Preoxygenation With Facemask Oxygen Group | For patients randomized to preoxygenation with facemask oxygen, supplemental oxygen will be administered via a non-rebreather mask or bag-mask device without manual ventilation from the initiation of preoxygenation until induction. Trial protocol will not dictate the brand or type of facemask. The decision between use of a non-rebreather mask and use of a bag-mask device will be made by treating clinicians. The decision of whether to provide manual ventilation with a bag-mask device between induction and laryngoscopy will be made by treating clinicians.~Facemask Oxygen: The delivery of supplemental oxygen via a non-rebreather mask or bag-mask device without manual ventilation from the initiation of preoxygenation until induction. Trial protocol will not dictate the brand or type of facemask. The decision between use of a non-rebreather mask and use of a bag-mask device will be made by treating clinicians. The decision of whether to provide manual ventilation with a bag-mask device between induction and laryngoscopy will be made by treating clinicians. | 535 | 656 | OG001 |
