Clinical trials: Preoxygenation
Obese
The Effect of Mask Combined With High Flow Oxygen on Preoxygenation During Induction of General Anesthesia in Obese Patients
There is a risk of airway-related incidents during anaesthesia associated with obesity. High-flow nasal oxygen is advocated for perioperative preoxygenation in obese patients to reduce airway adverse reactions.
