Shock – physical

shock physical

Medical shock is caused by not having enough blood circulating around your body. Reduced blood pressure decreases the flow of oxygen to vital organs and, unless attended to, is a life-threatening medical emergency.

Some of the many causes of medical shock include uncontrolled bleeding, severe burns, dehydration, being crushed under heavy objects, and spinal injury. A range of factors affects the impact of shock, such as your health, age, personality, where on the body the injury occurs and the environment. Shock can be particularly life threatening on farms where you may be a long way from help or emergency medical facilities.

It is very important that everyone on the farm knows where you are going to be and when you will return. It is also important for everyone on the farm to have some first aid training. If someone suffers a major injury, you must send for help and then try to stop any bleeding or treat wounds and burns.

Emotional distress or sudden fright in response to a traumatic event is also often called ‘shock’ but this is different from physical shock. More information about emotional shock can be found here: Better Health Channel – Trauma reaction and recovery.
