Comparison of Mask Ventilation Techniques in Patients Requiring General Anesthesia

"V-E approach maintains mouth open, creates larger oral cavity and allow positive pressure generated during inspiration to push forwards submandibular region.~When apnea occurs after anesthesia induction subjects will be ventilated with one of the two techniques randomly, either two-handed C-E facemask ventilation technique or with V-E technique. Ventilation will be carried out using pressure mode ventilation at respiratory rate of 10 breaths per minute. Subject will start with one technique and then cross over to the other technique."

"Using C-E technique, the operator's fingers pressure mouth closed and push posteriorily the soft tissue of submandibular region.~When apnea occurs after anesthesia induction subjects will be ventilated with one of the two techniques randomly, either two-handed C-E facemask ventilation technique or with V-E technique . Ventilation will be carried out using pressure mode ventilation at respiratory rate of 10 breaths per minute. Subject will start with one technique and then cross over to the other technique."
