Fainting
Fainting is a temporary loss of consciousness caused by a shortage of oxygenated blood to the brain. Common causes of fainting include:
- Fear or anxiety
- Lack of fresh air
- Severe pain, injury, or illness
- The sight of blood
- An underlying medical problem
- Fatigue or hunger
- Long periods of standing or sitting
- Overheating
A person who has fainted is unconscious. Place them in recovery position to protect the airway and prevent possible choking. Place the casualty in a comfortable position as they regain consciousness.
First Aid for Fainting
To give first aid for fainting, perform the following steps:
- Ensure a supply of fresh air and loosen tight clothing at the neck, chest, and waist.
- Make the casualty comfortable as consciousness returns and keep them lying down for 10 to 15 minutes. Continue to monitor breathing and consciousness.
Do not assume a person has “just fainted,” unless there is a quick recovery. If the recovery is not quick or complete, call 9-1-1 and stay with the casualty until they take over.
Feeling faint or “impending faint”
Sometimes when a person is about to faint, there are warning signs. The person:
- Will lack colour
- Is sweating
- Feels sick, nauseous, dizzy, or unsteady
First aid for an impending faint
To give first aid for an impending faint, perform the following steps:
- Place the casualty on their back.
- Ensure a supply of fresh air. Open windows or doors.
- Loosen tight clothing at the neck, chest, and waist.
- Stay with the casualty until they have fully recovered.
