Shock is the effect the body goes into when there is not a sufficient supply of oxygen and nutrients going to the major organs and functions of the body. The main vehicle the body uses to transport these nutrients and oxygen is the blood stream therefore most causes of medical shocks are thus blood related. A First Aider’s common consideration when it comes to shock is blood loss externally as well as internal blood loss. The body’s response to shock is to release adrenaline and to maintain blood volume to vital organs like the brain, lungs and heart.
The Different Types of Shock
Cardiogenic shock is where the pumping of blood volume is poor and not effective, for instance during a heart attack.
Hypovolemic shock is where the blood volume drops drastically due to blood loss internally or externally.
Anaphylactic shock is caused by a severe allergic reaction which causes the lungs to swell and therefore reducing or blocking the lungs ability to absorb enough oxygen and transferring it to the blood stream.
Signs and Symptoms of Shock
Sweating with cold and pale skin tone, usually because of reduced blood volume and dropping blood pressure.
Rapid pulse rate, to get more oxygenated blood to all parts of the body.
Nausea and vomiting, weakness and dizziness as the effects of the shock on the body increases.
Dry mouth and thirst, is the body’s response to try and increase the volume in the blood stream.
Rapid and shallow breathing, to get more oxygen into the body.
Weak and irregular pulse rate, because the heart is struggling to get enough blood to the vital organs.
Gasping for air, restlessness and finally unconsciousness. Now the body is completely shutting down to keep only the vital organs alive. By this time advanced medical help must act quickly to save the patient.
