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%

Classic signs of hypovolemic shock        

Marked tachycardia >120 bpm        

Marked tachypnoea >30 bpm        

Decreased systolic pressure        

Alteration in mental status        

Sweating with cool, pale skin

STAGE 4   40+%
