1. SHOCK
Presentation On

2. Definition Of Shock
 Shock is a life-threatening condition that occurs
when the body is not getting enough blood flow.
 Lack of blood flow means the cells and organs do
not get enough oxygen and nutrients to function
properly.

3. The main types of shock include
 Cardiogenic shock (due to heart problems)
 Hypovolemic shock (caused by too little blood
volume)
 Anaphylactic shock (caused by allergic reaction)
 Obstructive Shock (a decrease in the left
ventricular cardiac output)

5. Cardiogenic shock
 Cardiogenic shock takes place when the heart has
been damaged so much that it is unable to supply
enough blood to the organs of the body.

6. Causes
 Serious heart conditions (myocardial infarction).
 A large section of heart muscle that no longer moves well or does
not move at all
 Breaking open (rupture) of the heart muscle due to damage from
the heart attack
 Dangerous heart rhythms, such as ventricular
tachycardia, ventricular fibrillation, or supraventricular tachycardia
 Pressure on the heart due to a buildup of fluid around it (pericardial
tamponade)
 Tear or rupture of the muscles or tendons that support the heart
valves, especially the mitral valve
 Tear or rupture of the wall (septum) between the left and right
ventricles (lower heart chambers)
 Very slow heart rhythm (bradycardia) or problem with the electrical
system of the heart (heart block)

7.  Hypovolemic shock is an emergency condition in
which severe blood or other fluid loss makes the
heart unable to pump enough blood to the body. This
type of shock can cause many organs to stop
working.

8. Causes
 Losing about one fifth or more of the normal amount of blood in
your body causes hypovolemic shock.
 Blood loss can be due to:
 Bleeding from cuts
 Bleeding from other injuries
 Internal bleeding, such as in the gastrointestinal tract
 The amount of circulating blood in your body also may drop when
you lose too much body fluid from other causes. This can be due to:
 Burns
 Diarrhea
 Excessive perspiration
 Vomiting

9. Anaphylaxis Shock
 Anaphylaxis is a life-threatening type of allergic
reaction.

10. Causes
 Anaphylaxis is a severe, whole-body allergic reaction
to a chemical that has become an allergen. An
allergen is a substance that can cause an allergic
reaction.
 Anaphylaxis can occur in response to any allergen.
Common causes include:
 Drug allergies
 Food allergies
 Insect bites/stings

11. obstructive shock
 Obstructive shock is a condition that prevents blood
and oxygen from getting to your organs.

12. Causes
 Tension pneumothorax (collapsed lung).
 Vena cava compression syndrome (a large blood vessel that gets
compressed).
 Pulmonary (lung) compression syndrome.
 High-PEEP (positive end-expiratory pressure) ventilation (pressure
in your airways after the ventilator exhales).
 Tumors.
 Thromboembolism (clot) in the pulmonary artery.
 Pericardial tamponade (excess fluid around your heart compresses
it).
 Aortic dissection (a rip in your aorta).
 Aortic stenosis (the opening to your aortic valve gets narrow).
 Hypertrophic cardiomyopathy (thickened heart muscle causes
obstruction of flow out of your heart).
 Constrictive pericarditis (the sac around your heart gets thick).
