Which of the following is NOT a method to open an airway?

Opening an airway is a crucial procedure in providing emergency care, particularly in situations where a person may be unconscious or unable to breathe properly. The head-tilt/chin-lift method, jaw-thrust method, and manual jaw lift are all recognized techniques used to clear and open the airway.

The head-tilt/chin-lift method involves tilting the patient's head back gently and lifting the chin upward to help reposition the tongue and open the airway. The jaw-thrust method is particularly useful in cases where spinal injury is suspected; it involves pushing the jaw forward without tilting the head back, which helps open the airway while minimizing neck movement. The manual jaw lift also aims to assist in opening the airway by lifting the jaw forward to displace any tissues obstructing the airway.

Chest compressions, however, serve a different purpose. They are a foundational element of cardiopulmonary resuscitation (CPR) aimed at maintaining blood circulation during cardiac arrest but do not directly address airway obstruction. Thus, in the context of methods specifically intended to open the airway, chest compressions do not qualify.
