Conclusion
Shock is a condition in which:-
blood flow oxygen nutrients to the tissues
are inadequate for normal cell function
Shock can be caused by illness or trauma
Pump failure Loss of blood Loss of vascular tone
Hypovolemic shock
caused by blood loss external bleeding, internal
bleeding, loss of plasma (burns)
..continue
Cardiogenic shock
caused by heart (pump) failure heart attack
….continue
Respiratory Shock
Caused by insufficient oxygen in the blood
Chest injury, airway obstruction, or paralysis of the breathing muscles (e,g, from spinal injury)
…continue
Neurogenic Shock
Caused by loss of control of the nervous systems (loss of vascular tone)
Spinal cord injury
...continue
Metabolic Shock
Caused by the loss of body fluids Excessive diarrhea, vomiting, or
urination
…continue
Anaphylactic Shock
Caused by loss of vascular tone Extremely allergic, (e.g. insect
sting, foods, drugs, dust)
…continue
Psychogenic Shock (fainting)
Caused by loss of vascular tone Temporary condition Reaction to fear, bad news, the
sight of blood, or a minor injury
…continue
Septic Shock
Caused by a severe infection, Loss of vascular tone & blood
volume Contaminated IV, recent surgery,
prolonged illness or infection
…continue
1st stage of Shock
Compensatory Shock
2nd stage of Shock
Decompensatory Shock
To protect these organs, the body does the following:
Increases the rate & force of the heartbeat
Constricts the blood vessels of the skin
Selectively constricts/vasoconstriction some of the blood vessels in organs
Initial Signs
Lethargy or weakness Confusion Fear Irritability, Agitation Disorientation
The causes of compensatory shock are not corrected, decompensatory shock take place
B/P falls further Blood pools in the extremities &
cardiac output is reduced Usually results in death
Late Signs
Drowsiness, deteriorating to loss of consciousness
A change in level of consciousness Patient may be uncooperative,
abusive, or combative
Decreased LOC Decreased B/P (less than 90/60) Weak, rapid heart rate Pale, clammy, cool skin Shallow, rapid breathing Thirst
….continue
Restlessness, Anxiety Weakness Shivering
Management of Shock
RSE DABCs RBS
External bleeding
- Direct pressure Elevation the body part Use a tourniquet (Last resort only)
….continue
Internal bleeding
Minimize movement of the patient Keep the patient flat, raise & support
the legs Provide reassurance Never give the patient anything to
eat or drink Administer oxygen Rapid Transport
The Shock patient cannot be stabilized in the field
The Shock patient must be rapidly transported to a medical facility
