Recovery Position

When a person is unconscious and lying on their back, the airway can become compromised by the tongue falling back or any vomit thrown up by the casualty.
Placing the casualty in the recovery position protects the airway from the tongue and any vomit will run out of the mouth.
After Placing them in the Recovery position:
Call for an ambulance if you haven’t already done so
Keep talking to them, keep them warm and continue to monitor their breathing
If they have to be kept in the recovery position for more than 30 minutes, turn them to the opposite side to relieve the pressure on the lower arm
