Emergency Medical Technician (EMT) Intermediate Practice Exam

Where should the distal tip of the Cobra perilaryngeal airway (CobraPLA) be placed?

1. At the base of the tongue

2. Proximal to the esophagus, sealing the hypopharynx

3. In the trachea

4. Below the vocal cords

The correct answer is: Proximal to the esophagus, sealing the hypopharynx

The Cobra perilaryngeal airway (CobraPLA) is designed specifically to facilitate ventilation in patients with compromised airways. The correct placement of the distal tip being proximal to the esophagus, sealing the hypopharynx, is crucial for effective airway management. When the distal tip is positioned in this manner, it helps to create a barrier that prevents aspiration of secretions and maintains the airway's patency. This positioning enables the device to provide adequate ventilation by directing airflow toward the trachea while minimizing the risk of obstruction or displacement caused by anatomical variations. Understanding the anatomic landmarks of the airway is vital for effective use of this device. The base of the tongue and the region just below the vocal cords represent areas that, if targeted incorrectly, can lead to complications like airway obstruction or improper ventilation. Therefore, ensuring the CobraPLA is aligned properly at the hypopharynx level is essential for its intended function in emergency medical situations.
