Stages of Hypovolemic Shock
Hypovolemic shock
Results from significant and sudden blood loss within your body.
Blood loss of this magnitude can occur because of:
-
Bleeding from serious cuts or wounds.
-
Bleeding from blunt traumatic injuries due to accidents.
Tourniquets
S.T.A.T. Tourniquets 5 second application prevents further blood loss in the necessary time to prevent Hypovolemic Shock.
Emergency Blanket
Emergency Blankets help reduce the risk of Hypovolemic Shock and death.
S.T.A.T. Emergency Blankets can also be used to reflect light when signaling for help.

STAGE 1 15%

STAGE 2 15-30%
15-30% blood volume loss (750 - 1500ml)
Cardiac output cannot be maintained

Increased diastolic pressure
Narrow pulse pressure
Sweating from sympathetic stimulation
Mildly anxious/Restless
STAGE 3 30-40%
