| Fainting
occurs when the blood supply to your brain
is momentarily inadequate, causing you to lose consciousness.
This loss of consciousness is usually brief.Fainting
can have no medical significance, or the cause can be
a serious disorder. Therefore, treat loss of consciousness
as a medical emergency until the signs and symptoms
are relieved and the cause is known.If you feel faint:
Lie down or sit down.If you sit down, place your head
between your knees.Discuss recurrent fainting spells
with your doctor.

If
someone else faints:
Position the person on his or her back. Make sure the legs
are elevated, if possible above the heart level.
Check the person's airway to be sure it's clear. Watch for
vomiting.
Check for signs of circulation (breathing, coughing or movement).
If absent, begin CPR. Call 911 or your local emergency number.
Continue CPR until help arrives or the person responds and
begins to breathe.
Help restore blood flow. If the person is breathing, restore
blood flow to the brain by raising the person's legs above
the level of the head. Loosen belts, collars or other constrictive
clothing. The person should revive quickly. If the person
doesn't regain consciousness within one minute, call for emergency
medical assistance.
If the person was injured in a fall associated with a faint,
treat any bumps, bruises or cuts appropriately. Control bleeding
with direct pressure.
