Primary Study Endpoints In cohort 2 we will test the hypothesis that ventilation via a nasally placed ETT is superior in its efficacy (as measured by tidal volume) to routine facemask ventilation in patients undergoing endotracheal intubation for general anesthesia. In cohort 1 the patient population was restricted to patients undergoing oto-laryngologic or oral maxillofacial surgery that required nasal intubation.
