What is the proper positioning of the head to open the airway in BLS?

The proper positioning of the head to open the airway in Basic Life Support is accomplished using the tilt-chin lift maneuver. This technique is particularly effective because it helps to elevate the tongue away from the back of the throat, preventing airway obstruction caused by the tongue falling back, which is a common issue in unconscious patients.

To perform this maneuver, the rescuer places one hand on the forehead and uses the fingers of the other hand to lift the chin. This action creates a clear passage for air to enter the lungs and is especially important in emergency situations where every second counts.

The tilt-chin lift maneuver is suitable for most victims, particularly when there could be a need for rescue breathing, as it effectively facilitates ventilation. It's important to note that other techniques, like the jaw thrust maneuver, are used in specific scenarios, particularly when a spinal injury is suspected, but for general airway management where spinal injury is not a concern, the tilt-chin lift is the preferred method.
