Figure 1. The number of intubations according to each clinical indication. Respiratory failure includes patients intubated for hypoxemia and/or hypercarbia. Endotracheal tube (ETT) change was carried out because of ETT malfunction or to change the location of the ETT (i.e., oral to nasal). Procedure refers to intubation for procedures such as gastrointestinal endoscopy and bronchoscopy. Intubations for cardiac and respiratory (resp) arrest are combined.
