 After induction of general anesthesia and before placement of the endotracheal tube ETT or laryngeal mask airway LMA, the experienced anesthesia provider will attempt to ventilate the patient using an adult sized facemask. Each facemask will be pre-inflated with 150cc of room air and facemask will be placed over patients oral cavity utilizing the traditional one-handed C and E technique. The anesthesia provider will then provide a chin lift maneuver to 45 degrees and activate the ventilator 45 seconds after succinylcholine administration. A preset tidal volume of 8cckg will be delivered for 8 breaths. Any air leak will be noted and provider will attempt to minimize air leak. Tidal volumes TV, peak airway pressuresPAP will be recorded at each breath by an independent observer as well as heart rate HR, oxygen saturation rate spO2 and presenceabsence of Carbon dioxide - CO2.
