A drop in blood pressure reduces the flow of oxygen and nutrients to vital organs like the brain, heart, and lungs, and if the blood flow is not restored, the person may die from complications caused by a lack of oxygen supply to major organs (hypoxia).
Shock is a defence response
In medical terms, shock is the body’s reaction to a sudden drop in blood pressure. When a person experiences emotional distress or sudden fright, their body releases adrenaline into the bloodstream, which is known as ‘non-medical shock.’ This ‘non-medical shock’ is a response to anxiety or fear and is usually short-lived.
Symptoms of shock
Symptoms and signs of shock can include: pale, cold, clammy skin; low urine output or dark urine, depending on the cause.
Types of shock
Blood pressure can drop due to a variety of medical shocks, including internal (such as a ruptured artery or organ) and external bleeding, as well as obstructive shock, which is caused by a build-up of fluid in the pericardial sac around the heart.
First aid for shock
Medical shock is a life-threatening emergency, and prompt medical attention and effective first aid can save a person’s life. Assess the situation using the DRSABCD Action Plan. If the person is conscious, lie them down and keep them warm and comfortable.
Diagnosis of shock
Treatment for medical shock aims to restore blood circulation and manage or prevent complications. Tests may include: X-rays, ultrasound, CT scan, or MRI to check for internal bleeding. Electrocardiogram (ECG) – for example, an ECG may be required to diagnose cardiogenic shock.
Treatment of shock
Intravenous fluids can help stop bleeding and increase blood volume; in severe cases, a blood transfusion may be required. Medications that constrict (narrow) the blood vessels can help the heart pump more efficiently.
Outlook for people with shock
A person’s chances of surviving medical shock are determined by a variety of factors, including age and general health; approximately half of all cases of cardiogenic and septic shock result in death; hypovolaemic, neurogenic, and anaphylactic shock, on the other hand, respond well to treatment.

What are the 4 stages of shock?
It includes the initial stage, compensatory stage, progressive stage, and refractory stage of shock.
What are the 3 stages of shock?
SHOCK IN ITS EARLY STAGES
- The initial non-progressive phase
- the progressive phase
- the irreversible stage.
How long does shock last for?
Shock usually doesn’t go away on its own, so it will linger until you seek medical help. If you don’t seek medical help right away, you could end up in the hospital for weeks, and some people die from multiple organ failure.
Can you go into shock from pain?
Extreme pain causes neurogenic shock by overexciting the parasympathetic nervous system, resulting in a significant decrease in heart rate (Bradycardia), which lowers the pulse and lowers blood pressure dangerously [ shock ].
What happens to your body when you go into shock?
Shock is a defense response that causes vasoconstriction, which helps to conserve blood flow to vital organs, but it also causes the body to release the hormone (chemical) adrenaline, which can reverse the body’s initial response, causing blood pressure to drop, which can be fatal.
Can you go into shock from stress?
Acute stress disorder (ASD) is a psychological reaction to a terrifying, traumatic, or surprising experience. It is also known as acute stress reaction, psychological shock, mental shock, or simply shock.
What is the first sign of shock?
As complications worsen, shock symptoms may include weakness, rapid heart rate, rapid breathing, sweating, anxiety, and increased thirst, which may be followed by confusion, unconsciousness, or cardiac arrest.
How do hospitals treat shock?
- If the person is not breathing or breathing appears dangerously weak, lay the person down and elevate the person’s feet about 12 inches.
- Begin CPR, if Necessary. If the person is not breathing or breathing appears dangerously weak:
- Treat Obvious Injuries.
- Keep Person Warm and Comfortable.
- Follow Up.
What is traumatic shock?
Severe tissue damage, such as multiple fractures, severe contusions, or burns, characterizes traumatic shock.
How long are you in shock after a car accident?
People usually experience shock immediately after a car accident and for several days afterwards; shock can feel different for everyone, but common symptoms include feeling numb, emotional distress, continuing to feel afraid even after the event has passed, and having unpredictable mood swings.
What to do if someone is going into shock?
If the person shows no signs of life, such as not breathing, coughing, or moving, seek emergency medical help. Loosen tight clothing and, if necessary, cover the person with a blanket to prevent chilling. Don’t let the person eat or drink anything.
What are the symptoms of bad shocks?
The Signs That Your Shocks And Struts Are Worn
- Vehicle “tips” to one side in turns.
- The front end dives more than expected during hard braking.
- Rear-end squat during acceleration.
- Excessive tire bouncing.
- Unusual tire wear.
- Leaking fluid on the exterior of shocks or struts.
What are the 8 types of shock?
The following are the most common types of shock:
- Cardiogenic shock (caused by heart problems)
- Hypovolemic shock (caused by insufficient blood volume)
- Anaphylactic shock (caused by an allergic reaction)
- Septic shock (caused by infections)
- Neurogenic shock (caused by nerve damage).
What are the 7 types of shock?
18.9A: Shock Types
- Hypovolemic Shock.
- Cardiogenic Shock.
- Obstructive Shock.
- Distributive Shock.
How do you diagnose shock?
The following tests may be performed:
- Chest X-ray.
- Blood tests.
- Cardiac catheterization (angiogram).
- Electrocardiogram (ECG or EKG). This quick, noninvasive test records the electrical activity of your heart using electrodes attached to your skin.
