Jaw Thrust

What is the jaw thrust technique in first aid and when should it be used?

The jaw thrust is a critical first aid technique used to open the airway of an unconscious person, particularly when there is a concern about a spinal injury. Unlike the head tilt–chin lift method, the jaw thrust allows the rescuer to open the airway without moving the head or neck, helping reduce the risk of worsening a spinal injury.

To perform the jaw thrust, the rescuer kneels at the head of the casualty and places their hands on either side of the head. The fingers are placed behind the angle of the lower jaw, and the jaw is gently lifted upward and forward. This action helps move the tongue away from the back of the throat and opens the airway without shifting the spine.

This technique is commonly taught in advanced first aid and is particularly important in trauma situations, such as after a fall or motor vehicle accident, where spinal injuries may have occurred. The jaw thrust should be used with care and only by someone trained in its proper technique.

In any situation where spinal injury is suspected, maintaining spinal alignment while ensuring a clear airway is a top priority. The jaw thrust allows responders to manage the airway safely until professional help arrives.

Symptoms that may indicate the need to perform a jaw thrust:

• Unconsciousness
• No normal breathing
• Suspected spinal or neck injury
• Gurgling or obstructed breathing
• No chest movement

How to perform a jaw thrust:

• Kneel at the top of the person's head.
• Place your hands on either side of their head, with fingers under the jawbones.
• Gently push the lower jaw upwards and forward.
• Avoid tilting the head or moving the neck.
• Check for normal breathing and begin further first aid if needed.

Takeaway to Remember

The jaw thrust is a first aid technique used to open the airway of an unconscious person, especially when a spinal injury is suspected. It moves the jaw forward without tilting the head.
