Comparison of Oxygen Adminstration by Nasal Cannula and High Flow Cannula During Bronchoscopy

Oxygen Administration During Bronchoscopy in Children, High Flow and Common Nasal Cannula: a Randomized Controled Trial

Randomized controled trial to compare oxygen desaturation during fiberoptic bronchoscopy using oxygen administered with nasal prongs and high flow nasal cannula. Drops in oxygen saturation are frequent during bronchoscopy and limit the procedure compromising patient security. The investigator's aim is to contribute to select better way of oxygen administration which could prevent desaturations during bronchoscopy in children.

Inclusion Criteria:

• elective flexible bronchoscopy

Exclusion Criteria:

• admitted in Neonatal intensive care
• previous respiratory support: oxygen any device, non invasive or invasive ventilation
• patient who may benefit with continuous positive pressure during procedure
