Shock
Shock is a very serious health problem. It happens when the body’s organs and tissues do not get enough blood. Blood carries oxygen and important nutrients that the body needs to work well. Without enough blood flow, the organs can stop working properly. This can be very dangerous and must be treated quickly.

What Is Shock?
Shock means the body is not getting enough blood to keep working properly. This can happen after an injury, illness, or other emergency. When the body is in shock, the heart cannot pump blood strongly enough, or the blood vessels may be too wide or narrow. This causes less blood to reach the brain, heart, lungs, and other important parts of the body.
For example, if someone loses a lot of blood after a cut, their body might go into shock. Or if someone has a severe allergy and their blood vessels get very wide suddenly, that can also cause shock.

Why Is Shock Important in First Aid?
Shock is important because it can make a person very sick very quickly. Without first aid, shock can lead to loss of consciousness or even death. It affects many people in emergencies, like after accidents, burns, or severe infections.
Knowing the signs of shock can help you act fast and give the right help. This can save a person’s life before the ambulance or doctor arrives.

What Causes Shock?
There are many causes of shock. Some common ones include:
– Severe bleeding: Losing a lot of blood from a cut or injury.
– Heart problems: When the heart can’t pump blood properly.
– Allergic reactions: A big allergy attack can change how blood moves in the body.
– Serious infections: Infections can make blood vessels leak and widen.
– Severe burns or injuries: These can cause blood loss or fluid loss.
– Fainting or dehydration: Losing too much water can lead to shock.
Shock can happen after a serious accident, a bad fall, or other emergencies. It can also happen when the body gets too cold or overheats.

What Happens in the Body During Shock?
When someone is in shock, their body tries to fix the problem by doing things like making the heart beat faster and tightening blood vessels. This tries to keep blood flowing to the most important organs like the brain and heart. But if the cause of shock is not fixed, the blood flow keeps getting worse.
The person may start to feel weak, dizzy, or confused because the brain is not getting enough oxygen. Their skin may look pale or cool and feel clammy (wet and cold) to touch. Breathing may become fast or shallow.

What to Do if Someone Is in Shock
If you think someone is in shock, here are some general steps you can take to help:
1. Call for help. If the situation is serious, always call 000 right away for an ambulance. Do this before or while you help the person.
2. Keep the person lying down. If possible, lay the person flat on their back. This helps blood flow more easily to the brain and heart.
3. Raise their legs. If there are no injuries to the legs, hips, or head, gently lift their legs about 30 centimeters (or one foot) above the heart. This helps blood flow to vital organs.
4. Keep the person warm. Cover them with a blanket or clothing to stop them from getting cold. But don’t overheat them.
5. Don’t give food or drinks. The person might need surgery or treatment that requires an empty stomach. Giving food or drinks could be dangerous.
6. Loosen tight clothing. This allows the person to breathe easier.
7. Check their breathing and pulse. If they stop breathing or lose their pulse, begin CPR if you know how and stay with them until help arrives.
8. Stay calm and reassuring. Talk gently and keep the person as comfortable as you can.

What Not to Do
– Don’t move the person if you think they have serious injuries unless they are in danger where they are.
– Don’t give them anything to eat or drink.
– Don’t leave them alone.
– Don’t try to give medications unless directed by emergency services.

When to Call Emergency Services
Call 000 immediately if you see signs of shock or if the person is:
– Losing consciousness or not waking up
– Having trouble breathing
– Bleeding heavily
– Confused or very weak
– Suffering from a serious injury or illness
Emergency services will give you advice on what to do over the phone and send professional help as soon as possible.

How to Prevent Shock in Emergencies
You cannot always stop shock from happening, but some things can help reduce the risk:
– Stop bleeding quickly by applying pressure to wounds.
– Keep injured people still and supported.
– Protect people from getting too cold or too hot.
– Treat allergic reactions quickly by calling for emergency help immediately.
– Stay calm and act fast.

What Happens After First Aid for Shock?
Once emergency help arrives, trained paramedics will give the person the care they need. This might include giving fluids through a drip, helping with breathing, or fixing the cause of shock like stopping bleeding.
If you have helped someone in shock, try to stay with them and keep them calm until help arrives. Remember, your quick actions can make a big difference.
