Alternative Airway Devices and Adjuncts are important topics for the NEET PG exam because they play a critical role in the management of airway emergencies. Proper selection and use of alternative airway devices and adjuncts can make the difference between life and death for patients who are experiencing airway obstruction, respiratory distress, or cardiac arrest.
In order to effectively manage airway emergencies, healthcare providers must have a thorough understanding of the different types of alternative airway devices and adjuncts that are available, their indications for use, and the proper techniques for their insertion and maintenance.
This includes knowledge of various devices such as laryngeal mask airway (LMA), supraglottic airway devices (SGDs), and endotracheal tubes, as well as adjuncts such as oxygen masks, bag-valve-mask (BVM) devices, and chest compression devices.
In summary, the knowledge and skills related to Alternative Airway Devices and Adjuncts is essential for healthcare professionals, and is therefore an important topic in the NEET PG exam.

Pulls the tongue away from the airway and removes the obstruction.
Forward protrusion of jaw. Head is in neutral position and forward protrusion of the jaw with head kept stabilized in both hands.
Most common is Guedel’s airway. It is made up of rigid plastic. The size is determined from the angle of the lips to the angle of the mandible. It is inserted in an upside down position with a tip facing the roof of the mouth. Once it is half inserted, it is rotated to 180°.
In a conscious patient with compromised airway, we use nasopharyngeal airway. It is made up of soft silicon. The size is determined from the tip of the nose/ nostril to ear lobe. We insert it through the nasal cavity bevel facing the septum. It is a comfortable device. It can be inserted in a conscious patient.
