A Rates of severe hypoxemia during intubation procedure in patients with obesity after preoxygenation with non-invasive ventilation (grey bar) and high-flow nasal cannula oxygen therapy (dark bar). B Lowest individual pulse oximetry values during intubation procedure after preoxygenation with noninvasive ventilation (grey points) and high-flow nasal cannula oxygen therapy (dark points) in patients with obesity
