Shock
Definition:
A severe condition
that occurs when not enough blood flows through the body,
causing very low blood pressure,
a lack of urine (oliguria),
and cell or tissue damage.
Considerations:
Shock is caused
by any condition that dangerously reduces blood flow, including
heart problems (such as acute
MI or heart failure),
changes in blood vessels, changes in blood volume, and injuries.
Related factors include bleeding,
vomiting, diarrhea,
inadequate fluid intake (fluid
imbalance), and kidney disorders. Types of shock include
anaphylactic shock (caused
by allergic reaction),
bacteremia or septic
shock (associated with infections), cardiogenic
shock (associated with heart disorders), diabetic shock
(diabetic hyperglycemic hyperosmolar
coma), electric shock,
hypovolemic shock (caused
by inadequate blood volume), and neurogenic shock (caused
by damage to the nervous system).
Shock is a life-threatening condition that requires immediate
medical treatment. Some degree of shock can accompany any
medical emergency. Shock can get worse very rapidly. Be prepared
to begin rescue breathing or CPR
as needed.
