Hypovolemic shock
Alternative names:
shock - hypovolemic
Definition:
A form of shock; a
condition where the heart is unable to supply enough blood
to the body because of blood
loss, circulatory failure, or inadequate blood volume.
Causes, incidence, and risk factors:
Loss of approximately one-fifth of the normal blood volume
from any cause can cause hypovolemic shock. This includes
bleeding from the intestine
or stomach, other internal bleeding, external bleeding (from
cuts or injury), or loss of blood volume and body fluid (such
as can occur with diarrhea,
vomiting, intestinal
blockage, inflammations, burns,
and so on). Cardiogenic shock
is a similar form of shock
where there is adequate blood volume, but the heart is unable
to pump the blood. Other causes of shock include: overwhelming
infection, heart attack or disease, hormonal insufficiency,
hypoglycemia, hypothermia, allergic reaction, drug overdose,
and spinal cord injury.
