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.


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%    

Up to 15% blood volume loss (750ml)    

Blood pressure maintained    

Normal respiratory rate    

Pallor of the skin    

Slight anxiety

STAGE 2   15-30%    

15-30% blood volume loss (750 - 1500ml)    

Cardiac output cannot be maintained    


Increased respiratory rate    

Blood pressure maintained    

Increased diastolic pressure    

Narrow pulse pressure    

Sweating from sympathetic stimulation    

Mildly anxious/Restless

STAGE 3   30-40%    

30-40% blood volume loss (1500 - 2000ml)    

Systolic BP falls to 100mmHg or less    

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+%    

Loss greater than 40% (>2000ml)    

Extreme tachycardia with weak pulse    

Pronounced tachypnoea    

Significantly decreased systolic blood pressure    

Decreased level of consciousness    

Skin is sweaty, cool, and extremely pale (moribund)
