Which technique is utilized to assess and maintain a patent airway during CPR?

The head-tilt, chin-lift maneuver is the recommended technique for assessing and maintaining a patent airway during CPR. This maneuver opens the airway by extending the neck slightly and lifting the chin forward, which helps to prevent the tongue from obstructing the airway. It is particularly effective for unresponsive patients and is a standard practice in both basic life support and advanced cardiac life support protocols.

This technique is essential because a clear airway is critical for effective ventilation and oxygenation during CPR. Without a patent airway, even competent chest compressions will not be effective in circulating oxygenated blood, thus greatly impacting the chance of survival.

The jaw thrust maneuver is also a valid method for opening the airway, especially in trauma situations where spinal injury may be a concern, but it is not the first choice in most CPR scenarios. The argon release technique is not a recognized or applicable strategy within CPR guidelines. The hand positioning method relates to how compressions are delivered rather than airway management.
