In this study, we compare the conventional laryngeal handshake technique and modified laryngeal handshake technique for locating the cricothyroid membrane in terms of accuracy and speed. The conventional laryngeal handshake technique is performed with the non-dominant hand, identifying the hyoid bone and thyroid laminae, stabilizing the larynx between thumb and middle finger, and moving down the neck to palpate the cricothyroid membrane with the index finger. The modified laryngeal handshake is performed with the non-dominant hand, stabilizing the trachea between thumb and middle finger from the suprasternal notch and moving up the neck to palate the cricoid cartilage and cricothyroid membrane with the index finger.
