Shock Flashcards
PATHOPHYSIOLOGY OF SHOCKS
Blood does not circulate effectively to
the body’s tissues.
Three conditions are necessary for maintaining perfusion
- The heart must be functioning effectively.
- An adequate quantity of blood must be circulating in the body.
- The blood vessels must be able to control blood flow by dilating and constricting.
CARDIOGENIC SHOCK
Cardiogenic shock is the result of a problem with
the heart itself.
OBSTRUCTIVE SHOCK
Obstructive shock occurs when something
physically prevents the heart from filling or
emptying effectively, even if it is otherwise
pumping normally.
HYPOVOLEMIC SHOCK
Hypovolemic shock is the general term for shock
that results from an insufficient volume of blood
circulating in the body
Hemorrhagic Shock
Hemorrhagic shock is the most common type
of true hypovolemic shock, occurring when the
vascular system rapidly loses a large quantity of
blood due to hemorrhaging.
NEUROGENIC Shock
Occurs when the nervous system losses its ability to control the constriction of the body blood vessels
PSYCHOGENIC SHOCK
Psychogenic shock is a form of relative
hypovolemic shock (distributive shock) that results
from emotional stress.
Septic Shock
For of relative hypovolemic shock occurs as the result of severe infection
ANAPHYLAXIS Shock
Occurs when result of extreme allergy
Stages of shock
1) compensated shock
2) de-compensated shock
3) irreversible shock
Care for shock
Early recognition
Help the patient rest comfortably in the recovery
or supine position. A supine position will help
increase blood flow to the patient’s vital organs,
especially the brain
Elevating the patient’s feet
20 to 30 cm (8 to 12 in.) can help improve blood
flow to the head and torso
Check ABC
Help patient remain normal body temperature
