Shock

Shock :

Shock occurs when the circulation system fails to send blood to all parts of the body. With shock, blood flow or blood volume is too low to meet the body's needs. Areas of the body are deprived of oxygen. The result is damage to the limbs, lungs, heart, and brain.

Causes :

There are many causes for shock, including:

heart attacks

severe trauma, such as a serious motor vehicle accident

infections

diabetes

loss of blood

head injury

anaphylaxis, which is a severe allergic reaction

severe vomiting

hypothermia, or a drop in body temperature due to cold exposure

severe diarrhea

Signs & Symptoms :

Weakness. Trembling.

Feeling restless. Confusion.

Pale or blue-colored lips, skin, and/or fingernails. Cool and moist skin.

Rapid, shallow breathing. Weak, but fast pulse.

Nausea. Vomiting. Extreme thirst.

Enlarged pupils.

Loss of consciousness.

Treatment :

Shock is a life-threatening condition and requires emergency medical treatment immediately.

If you suspect shock, even if the person seems normal after an injury:

• Call the emergency number.
• Have the person lie down on his or her back with feet about a foot higher than the head. If raising the legs will cause pain or further injury, keep him or her flat. Keep the person still.
• Check for signs of circulation (breathing, coughing or movement). If absent, begin CPR.
• Keep the person warm and comfortable. Loosen belt and tight clothing and cover the person with a blanket. Even if the person complains of thirst, give nothing by mouth.
• Turn the person on his or her side to prevent choking if the person vomits or bleeds from the mouth.
• Seek treatment for injuries, such as bleeding or broken bones.
