As an unconscious person lies on their back, hook their back leg, and place the arm on that side onto their chest. Place their other arm pointing obliquely upwards.
After positioning the limbs, grab the unconscious person by the shoulder and the hooked knee and turn them carefully to face you. Place the arm that was on their chest under their cheek and leave the leg hooked to support them in the new position.
Finally, make sure the airway remains open by lifting the unconscious person’s chin.
In a correctly executed side position, the unconscious person will be lying on their right side, stable, and safe from their tongue blocking their airway. If the unconscious person vomits, the side position prevents the vomit from entering their airway.
