Thyroid cartilage elevation maneuver: a novel and easy-to-perform method to insert a supraglottic airway device

The 2019 American Heart Association guideline recommends SAD insertion in emergency situations, such as out-of-hospital cardiac arrest. According to one study, when a SAD was used in an emergency medical service (EMS) setting, airway failure was not recognized in 13.8% of patients. The paramedics performed two rounds of cardiopulmonary resuscitation with 200 J defibrillation, and after 4 min, the patient gained a return of spontaneous circulation. [...]during SAD insertion, the tip may be malpositioned due to resistance from laryngeal structures, resulting in inadequate ventilation like air leakage or obstruction.
