Physiological effects of trans-nasal humidified rapid insufflation ventilatory exchange (THRIVE) on lung volume dynamics during controlled apnea in patients with obesity: a randomized controlled trial.
BACKGROUND Obese patients are prone to rapid oxygen desaturation during induction of general anesthesia due to reduced functional residual capacity and atelectasis formation. Transnasal humidified rapid insufflation ventilatory exchange (THRIVE) prolongs safe apnea time; however, its effects on lung volume dynamics dur...
