Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
