What this trial studies

This study evaluates the effectiveness of High Flow Nasal Oxygen (HFNO) using the Optiflow Switch during tracheal intubation in critically ill patients. It compares traditional preoxygenation methods with the addition of HFNO to determine if it reduces the risk of hypoxaemia and other adverse events during intubation. The study will involve a before-and-after design, including a minimum of 50 patients over a period of 6-12 months. Patient characteristics and vital parameters will be monitored before, during, and after the intubation process.

Who should consider this trial

Good fit: Ideal candidates are adult patients in intensive care who require tracheal intubation.

Not a fit: Patients with skull or facial injuries, total nasal obstruction, or those deemed unsuitable for other reasons will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of hypoxaemia during intubation in critically ill patients.

How similar studies have performed: Previous studies have shown mixed results regarding the use of HFNO during intubation, making this approach both relevant and potentially novel.
