To open the airway when the victim is unresponsive and there is no neck injury, which method should be used?

The head tilt-chin lift method is the appropriate technique to open the airway in an unresponsive victim without a suspected neck injury. This method involves tilting the head back gently while simultaneously lifting the chin upwards, effectively moving the tongue away from the back of the throat and allowing for unobstructed airflow.

This technique is preferred as it is easy to perform and highly effective in maintaining an open airway, facilitating proper ventilation and air exchange in situations of respiratory distress. The method is particularly useful in cases where there is no spinal injury, as it does not compromise the cervical spine.

In contrast, the jaw thrust method is typically used when there is a possibility of neck or spinal injuries, as it minimizes head movement and focuses on moving the jaw forward to clear the airway. Therefore, while it is a valuable technique in certain scenarios, it is not the best choice when a neck injury is not a concern.

Neck extension is not a recommended method for opening the airway as it could lead to potential airway obstruction. The chin lift method alone, without the head tilt, may not be as effective in fully opening the airway since it may not adequately reposition the tongue.

Understanding the correct method to use based on the circumstances is vital for effective airway management and resusc
