  1. Comparison of Randomized Groups on perioperative variables of oxygenation and ventilation. Data are presented as N (%), mean (SD) or median (IQR). THRIVE Transnasal Humidified Rapid Insufflation Ventilatory Exchange, LMA Laryngeal Mask Airway, SctO2 cerebral tissue oxygen saturation, SpO2 pulse oxygen saturation, PACU Post-Anesthesia Care Unit, PaCO2 partial pressure of carbon dioxide. P value corresponded to Wilcoxon rank sum test or Fisher’s exact test
