4. INTRODUCTION
Shock is a life threatening medical condition where by
the body suffers from insufficient blood flow the
throughout the body (circulatory collapse) it is
characterized by inadequate tissue perfusion in which
there is insufficient delivery of oxygen and nutrients to
the body’s tissue and inadequate removal of waste
product from the tissues if untreated ,results in cell
death this can damage multiple organs.
Failure of the normal regulatory mechanisms in the body
can lead to rapid and profound shock .shock often
accompanies severe injury or illness

5. DEFINITION
 According to javed ansari :- shock is a condition
in which the cardiovascular system fails to
perfuse tissue adequately
According to Nima schwartz’s :- Shock may be
defined as inadequate deliver of oxygen and
nutrients to maintain normal tissue and
cellular function

6. INCIDENCE
 Most couses reported in western
countries still involve menstruating
women under age 30. TSS still occurs in
about 17 out of every 100,000
menstruating girls and women eases are
related to tampons between 5% and 10%
of patients with TSS die

11. HYPOVOLEMIC SHOCK

vascularcompartment

13. CARDIOGENIC SHOCK
1) Shock resulting from inadequate pumping action of the
heart because of cardiac muscles disfunction or mechanical
obstruction to the blood flow.
2) Cardiogenic shock is a state in which the heart is been
damage so much that it is unable to supply enough amount
of blood to the organs.

 Septicshock
 Neurogenicshock
 Anaphylaticshock

15. SEPTIC SHOCK
 It is the most common shock that is caused by
pathogen in blood endotoxins (it is the type of
infection of blood) .
It released vasodilator they also activate
complement pathway which stimulate master cell
(histamine) another vasodilator .
In septic shock the blood flow is high due to this
heat production increased by the body so
distributive shock is also known as warm shock.

16.  This is caused by allergic reaction of the body
against some microorganism
It may also lead to low blood pressure
ANAPHYLACTIC SHOCK

17. NEUROGENIC SHOCK
 In neurogenic shock the nervous system can damage
due to some incident or accident lead to low blood
pressure .

18. OBSTRUCTIVE SHOCK:-
 Obstructive shock is used as another
category of shock to include those
conditions that leads to a sudden
obstruction of blood flow .
 Obstructive shock occurs when there is
a blockage of blood flow in the
cardiovascular circuit outside the heart.

19. Stages Of Shock

20. PATHOPHYSIOLOGY:-
 Due to risk factor or precipitation causes of shock
Decreased circulatory blood volume which leads to
decreased cardiac output
Cells lack an adequate blood supply and are deprived
oxygen and nutrition

22.  Because of these changes normal cell function cease
causes cell membrane dysfunction
 The cell swells and its membrane become more
permeable and failure of sodium pump
 Toxic substance enter circulation and damage
capillary endothelial
 Death of cell occur (shock)

24.  Bluish nail .
 Anxiety,
 Chest pain,
 Confusion,
 Urine output,,
 Unconsciousness ( coma)

27. Medical Management
 Respiratory support
 Circulatory support
 IABP

28. PHARMACOLOGICAL MANAGEMENT
 Vasoconstriction
 Vasodilators .
.

29. Nursing Management
•To improve oxygenation.
•Temperature monitoring.
•Cardiac monitoring.
•I/V fluid administration.
•Psychological support.
•Blood transfusion.
