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%    

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    

Tachycardia    

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)
