No mask needed? new device may simplify anesthesia start

This study tested whether a device called Optiflow, which delivers warm, humidified oxygen through the nose, could replace the usual face mask during the start of anesthesia. The goal was to see if it could safely oxygenate patients without needing to hold a mask on their face. Sixty adults undergoing general anesthesia with oral intubation took part, and researchers filmed the process to check if mask ventilation was still required.
