Cricothyroidotomy is an emergency rescue technique to secure the airway in a 'Can't intubate, Can't Oxygenate' (CICO) situation. The cricothyroid membrane (CTM) is the target site of cricothyroidotomy, and accurate identification of the CTM is essential for successful cricothyroidotomy. In this study, the investigators compare patient positions (neck extension vs. modified ramped position) in terms of the success rate for identifying the CTM in obese patients.
