Aktiv komparator: Manual Ventilation
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.

Aktiv komparator: No Manual Ventilation
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.

Ventilator-free days
Tidsram: 28 days
|
Ventilator-free days to day 28 will be defined as the number of days alive and with unassisted breathing to day 28 after enrollment, assuming a patient survives for at least two consecutive calendar days after initiating unassisted breathing and remains free of assisted breathing.
If a patient returns to assisted breathing and subsequently achieves unassisted breathing prior to day 28, VFD will be counted from the end of the last period of assisted breathing to day 28.
If the patient is receiving assisted ventilation at day 28 or dies prior to day 28, VFD will be 0. If a patient is discharged while receiving assisted ventilation, VFD will be 0. All data will be censored at the first of hospital discharge or 28 days.

Intensive care unit-free days
Tidsram: 28 days
|
ICU-free days to 28 days after enrollment will be defined as the number of days alive and not admitted to an intensive care unit service after the patient's final discharge from the intensive care unit in that hospitalization before 28 days.
Patients who are never discharged from the intensive care unit will receive a value of 0. Patients who die before day 28 will receive a value of 0. For patients who return to an ICU and are subsequently discharged prior to day 28, ICU-free days will be counted from the date of final ICU discharge.
All data will be censored at the first of hospital discharge or 28 days.
