When giving breaths to an adult using the head-tilt/chin-lift technique, what is the correct position of the head to ensure an open airway?

• A. Tilt the head back so the airway is in a neutral position
• B. Tilt the head back until the chin points upward
• C. Turn the head to one side
• D. Keep the head flexed forward toward the chest

Answer: (B)

Verified step by step guidance

1. Understand the purpose of the head-tilt/chin-lift technique: This maneuver is used to open the airway by preventing the tongue from obstructing the throat, which is crucial for effective ventilation during CPR or rescue breathing.
2. Identify the anatomical structures involved: The tongue, pharynx, and trachea are key structures that can obstruct the airway if the head is not positioned correctly. Tilting the head back helps align these structures to create a clear path for air to flow.
3. Determine the correct position: The head should be tilted back until the chin points upward. This position extends the neck and lifts the tongue away from the back of the throat, ensuring the airway is open.
4. Avoid incorrect positions: Keeping the head flexed forward toward the chest or turning the head to one side can obstruct the airway. Similarly, a neutral position may not sufficiently open the airway for effective ventilation.
5. Practice the technique safely: When performing the head-tilt/chin-lift, ensure you use gentle pressure to avoid causing discomfort or injury to the individual, especially if there is a possibility of spinal injury.
