Fainting happens when you lose consciousness for a short amount of time because your brain isn’t getting enough oxygen. Full recovery usually takes a few minutes. If there is no underlying medical condition causing you to faint, you may not need any treatment.
A faint is a brief loss of consciousness caused by a temporary reduction of blood flow to the brain. Fainting can be a reaction to emotional stress, lack of food, pain, or exhaustion.
A faint can also be caused by long periods of inactivity such as standing or sitting still, especially in a warm atmosphere.
When a person faints, the pulse rate becomes very slow. However, the rate soon returns to normal and a casualty who has fainted usually makes a rapid and complete recovery.
Follow these simple steps to help someone who feels faint:
Advise the casualty to lie down and raise their legs to improve blood flow to the brain.Watch the casualty’s face for signs of improvement.
Make sure that the casualty has plenty of fresh air, open a window if you are indoors, and ask any bystanders to stand clear.
As the casualty recovers, reassure them and help them to sit up gradually.
If the casualty feels faint again, advise them to lie down again and raise their legs until they recover fully.
If the casualty does not regain consciousness quickly, open the airway, and check breathing, and call for an emergency.
