Pre-oxygenation in obese patients: facemask versus facemask with nasal prong

open access: yesMalaysian Journal of Anaesthesiology, 2023
Introduction: Anatomical and physiological changes of the respiratory system in obese patients predispose them to rapid oxygen desaturation during apnoea. Adequate pre-oxygenation before anaesthesia induction allows a period of safe apnoea. The efficacy of pre-oxygenation with facemask versus facemask with nasal prong was compared.
