Shock (circulatory) Facts for Kids

When a person is in shock, it means their body isn't getting enough blood flow. This is a very serious condition because blood carries oxygen and important nutrients to all parts of the body, especially the brain and other vital organs. Without enough oxygen, these organs can get damaged. Shock can get worse very quickly and can be deadly if it's not treated right away.

Shock is not just being surprised; it's a medical emergency. It happens when the circulatory system (your heart and blood vessels) can't deliver enough blood to meet the body's needs. This can be caused by many different things, like losing a lot of blood, severe infections, or serious allergic reactions.

What Happens During Shock?

When someone is in shock, their body tries to protect itself. It might try to send more blood to the most important organs, like the brain and heart, and less to other areas, like the skin or muscles. This is why someone in shock might look pale or feel cold.

Signs and Symptoms of Shock

It's important to know the signs of shock so you can help someone quickly.

Pale, cool, or clammy skin: The skin might feel cold and sweaty.
Fast, weak pulse: Their heart beats very quickly, but the pulse feels faint.
Rapid, shallow breathing: They breathe very fast, but not deeply.
Feeling dizzy or faint: They might feel lightheaded or confused.
Feeling very thirsty: This is a common symptom.
Feeling anxious or restless: They might seem agitated.
Loss of consciousness: In severe cases, they might pass out.

Types of Shock

There are several types of shock, depending on what causes it.

Hypovolemic shock: This happens when there isn't enough blood or fluid in the body. It can be caused by severe bleeding from an injury or by losing a lot of fluids from vomiting or diarrhea.
Cardiogenic shock: This occurs when the heart can't pump enough blood to the body. It's often caused by a serious heart attack.
Anaphylactic shock: This is a very severe allergic reaction. It can happen if someone is extremely allergic to something like a bee sting or certain foods. Their body reacts by releasing chemicals that make blood vessels widen and blood pressure drop.
Septic shock: This is caused by a severe infection that spreads throughout the body. The infection can make blood vessels leak, leading to a drop in blood pressure.
Neurogenic shock: This type of shock happens after a serious injury to the spinal cord. It affects the nervous system's control over blood vessels.

First Aid for Shock

If you think someone is in shock, it's a medical emergency. You should get help right away.

Call for help: Get an adult or call emergency services immediately.
Lie them down: Have the person lie flat on their back.
Elevate the legs: If there are no injuries to the head, neck, back, or legs, gently lift their legs about 12 inches (30 cm) higher than their head. This is called the Trendelenburg position. It helps blood flow back to the brain and heart.
Keep them warm: Cover them with a blanket or coat to prevent them from getting too cold.
Do not give them food or drink: They might need medical procedures that require an empty stomach.
Stay with them: Keep them calm and comfortable until medical help arrives.
