What this trial studies

This study evaluates the effectiveness of three different pre-oxygenation strategies: using a non-rebreather face mask, a bag-valve-mask with positive end-expiratory pressure, and a bag-valve-mask without additional pressure. The study involves spontaneously breathing volunteers and aims to measure various endpoints, including expiratory oxygen concentration and Oxygen Reserve Index at different time points during the pre-oxygenation sessions. A total of 45 participants will be enrolled, divided into three subgroups, to assess the differences in oxygenation strategies.

Who should consider this trial

Good fit: Ideal candidates include normal-weight adults and healthy children aged 6-12 years who meet specific ASA classification criteria.

Not a fit: Patients with ASA classification of 3 or those with acute respiratory illnesses may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could optimize pre-oxygenation techniques, improving patient outcomes during anesthesia and emergency situations.

How similar studies have performed: While the specific approaches may be novel, similar studies have explored pre-oxygenation strategies, indicating potential for meaningful insights.
