First aid
If an individual becomes unconscious, these measures must be taken:
- Assess if the individual is breathing. If not, call for emergency assistance. If breathing, place on his/her back.
- Elevate the legs of the individual to at least 12 inches above the ground
- Loosen up any tight clothing or belts. If the individual does not regain consciousness in one minute, call for emergency assistance.
- Assess the airway to ensure that there is no obstruction or blockage
- Check if the individual is breathing, moving or coughing. These are indications of confirmed circulation. If these are absent, execute CPR until the emergency team arrives.
In case unconsciousness is brought about by low blood pressure, the doctor will administer intravenous medications to increase the blood pressure. If the blood sugar is low, provide candy or a glucose injection is given.
