Advanced Cardiovascular Life Support (ACLS) Practice Exam

What is the potential danger of using ties that pass circumferentially around the patient's neck when securing an advanced airway?

1. Increased risk of aspiration

2. Obstruction of venous return from the brain

3. Pneumothorax risk

4. Decreased airway patency

The correct answer is: Obstruction of venous return from the brain

Using ties that pass circumferentially around the patient's neck when securing an advanced airway can indeed pose a significant risk of obstructing venous return from the brain. This concern arises from the potential for the ties to compress the major veins in the neck, specifically the internal jugular veins, which are crucial for draining blood from the head back to the heart. When these veins are compressed, it can lead to increased intracranial pressure due to the impaired venous drainage. This increased pressure can result in a series of complications, including altered mental status and potential neurological damage. It's essential to secure the airway without compromising blood flow to the brain, which is why alternative methods, such as using ties that do not encircle the neck completely or using other securing mechanisms, are often recommended in advanced airway management. By understanding this risk, healthcare providers can better position their airway securing devices, ensuring they provide effective ventilation and oxygenation while also protecting the patient's neurological status.
