Why it is important to tilt the head of an unconscious person when perfoming mourh mouth resuscitation?

Tilting the head of an unconscious person when performing mouth-to-mouth resuscitation is crucial for ensuring the effectiveness and safety of the procedure. Here's why it is important:

1. Clearing the Airway: Tilting the head of an unconscious person helps clear the airway by repositioning the tongue and keeping it from blocking the airway. When a person is unconscious, the muscles in the body, including the tongue, relax. This can cause the tongue to fall back and obstruct the airway, making breathing difficult or impossible.

2. Preventing Aspiration: Tilting the head helps prevent aspiration, which is the accidental inhalation of foreign objects, like vomit or fluids, into the lungs. By tilting the head back slightly, the airway is positioned in a way that helps direct air into the lungs and reduces the risk of aspiration.

3. Facilitating Resuscitative Efforts: When the head is tilted, it aligns the mouth and nose with the trachea, allowing for more effective airflow during rescue breaths. This proper alignment ensures that air is being delivered directly into the person's lungs, optimizing the effectiveness of mouth-to-mouth resuscitation.

4. Reducing Strain: Tilting the head reduces the strain on the rescuer's back and arms. By elevating the person's head, the rescuer can perform mouth-to-mouth resuscitation more comfortably, ensuring they can provide sustained and effective rescue breaths.

5. Avoiding Compression of Airway Structures: Tilting the head helps prevent compression of airway structures, such as the epiglottis, that might be blocking the airway. By carefully positioning the head, the rescuer can minimize obstructions and facilitate better airflow.

It's important to note that while tilting the head is a crucial step in performing mouth-to-mouth resuscitation, it should be done gently and with caution to avoid causing further injury to the person. Additionally, tilting the head alone is not sufficient to clear the airway; it should be combined with other techniques such as the jaw-thrust maneuver or finger sweep to effectively remove any airway obstructions.
