Shock – Signs, Symptoms, Causes, Treatment – Video Explanation
Medical professionals like, doctors, first aid providers, pharmacists, and nurses often come across the term “shock” or “hypoperfusion” when it comes to providing first aid to the patient – we are going to explain you through, the video below, and detailed article about what is shock, its types, signs, symptoms, and possible treatment options.
The video explains the shock and its different types in just 2 minutes in a very brief and easy to understand way.
The video already gained 500K+ views on our YouTube Channel so far and increasing. Don’t believe it? See yourself here at Lifestyle by IK YouTube Channel.
If you are going to provide first aid, you must understand all types of shock. For that reason, we have also written details of the shock below. This is in case you don’t find anything in the video above.
Definition of Shock
“Shock or hypoperfusion is the inability of the circulatory system of our body to supply cells with oxygen.”
When the body is unable to get blood flow to the organs, tissues, and cells, the shock becomes life-threatening which leads to organ failure and ultimately death. Because of the severity of the condition, a quick fist aid is required.
In the early stages, symptoms occur as the body attempts to compensate for blood loss.
The Signs of Shock
A person with shock may produce the following signs and symptoms:
Low blood sugar levels
Low blood pressure
Pale, cool skin
Lightheadedness or fainting
Agitation or anxiety
Blue colored lips (gray if a person has a dark complexion)
Blue colored fingernails (gray in case of a dark complexion)
Causes of Shock
Shock may be caused by:
- Massive infection or an anaphylactic or severe allergic reaction may also cause shock from blood vessel dilation.
- Accident causing heavy internal or external bleeding
- Severe infection in the body
Physiological causes are the heart failing to pump (heart attack or heart failure). Loss of blood volume or blood vessels dilating creating a vascular container capacity that is too great to be filled by available blood. This may be due to excessive bleeding or dehydration.
Different Types of Shock
There are 5 different types of shock that are as follows:
Now let’s answer questions about 5 types of shock one by one.
1 – Compensated Shock?
It presents as an increased heart rate, increased respiration, and constriction of peripheral circulation. This results in pale cool skin. In infants and children, increased capillary refill time occurs.
2 – Decompensated Shock?
It starts with low blood volume or a lack of perfusion. Symptoms include falling blood pressure. Shock is irreversible when perfusion to the organs cannot be restored.
Cell damage occurs, especially in the liver and kidneys. Even if vital signs are restored, irreparably damaged organs may cause death.
3 – Hypovolemic Shock?
It is caused by uncontrolled hemorrhage, internal or external, or both, or by plasma loss in burns or crush injuries.
4 – Cardiogenic Shock?
Cardiogenic shock occurs during a myocardial infarction or heart attack; damaged heart muscle; or electrical malfunctioning decreases the strength of the heart’s contractions causing a slow-fast or irregular heartbeat.
Treatment of cardiogenic shock
Treatment of cardiogenic shock includes quick restoration of blood pressure and heart function while taking patients in an ambulance or in an emergency room.
Emergency medical treatment may include enriched oxygen in a tube or masks; respiratory assistance (ventilator); intravenous (IV) fluids and medicines to boost blood pressure or heart function.
There may be an array of medicines that may be given to deal with cardiogenic shock. These differ relying upon the reason for the shock and will include:
- Thrombolytic medicine to dissolve coronary artery clots (“clot-busting” drugs similar to tPA)
- Anti-clotting agents to stop new clots (e.g., aspirin, clopidogrel, heparin)
- Medication to extend the heart’s pumping capacity (e.g., dobutamine, dopamine, epinephrine)
- Different potential therapies include oxygen to guard heart tissue; nitroglycerin to widen coronary vessels; medication to lower the heart’s workload and pain, relieve anxiety, or regulate heart rhythm
5 – Neurogenic Shock?
It may result from the uncontrolled dilation of blood vessels due to nerve paralysis in spinal cord injuries. There is no blood loss, but the blood vessel dilation increases the capacity of the circulatory system and available blood can no longer fill it.

Treatment – Course of Action – First Aid of Shock
Before proceeding with the first aid, your first and foremost course of action should be to call 911 or any other local emergency number of your respective country to get immediate medication attention.
You need to stay with the person. You should also stay on the call with the emergency team as they may provide you important instructions to handle the situation at the time.
As a first aid provider, for almost all types of shocks, the first line of treatment is fluid resuscitation. This means you should provide the patient with a large volume of IV fluids. As a result of this, the blood pressure of the patient will increase.
IV fluids may be administered by the ambulance staff when they are on way to the hospital or may be administered in the emergency room.
Do not administer fluids by mouth. There is a chance of choking in case the patient gets unconscious. Do not do this even if the patient complains of thirst or dry mouth.
After you have called 911 or your local emergency, you can perform the following first aid:
- Lay the patient down straight
- Slightly raise the legs & feet and make sure the patient doesn’t feel pain
- Keeping the patient still is preferred; don’t move unless it is very necessary.
- If you see there are no signs of life like breathing, movement or coughing, etc. then start the Cardiopulmonary Resuscitation (CPR), if you have training.
- The patient may be wearing tight clothes, lose them immediately to prevent the patient from suffocation.
- Shock may be due to an external injury, you should apply direct pressure to the wound site to prevent blood loss.
- If the patient feels chills or very cold, cover with a blanket.
- The patient may show signs of bleeding from the mouth or vomiting, which may cause choking. To prevent this, turn the patient on to aside. Make sure this doesn’t cause spinal injury in case the patient is injured from the back.
Shock in first aid (or hypoperfusion in first aid) is a life-threatening medical condition in which there is reduced oxygen supply to the cells through the circulatory system. This causes reduced blood supply to the organs, as a result, they stop functioning. There are 5 different types, namely compensated, decompensated, hypovolemic, cardiogenic, and neurogenic. Medical treatment depends on the type of shock. As an Emergency Medical Technician (EMT), you do not need to diagnose the type; instead, you must recognize and treat for a shock whenever there is a mechanism of injury or signs that indicate the possibility of shock. Always call the emergency helpline in your local area of your respective country.
