Yorkshire based company, Haemoconcepts Ltd specialise in vacuum compression technology for the global medical market. Their innovation covers all aspects of medical care: for civilians in a first response role, trained first responders, workplace medical care, and the military and veterinary market. Here they discuss the importance for prompt action when treating a blood loss wound.
Blood as we know carries oxygen around the body, particularly to the brain. Oxygen is essential for maintaining normal brain function. A sudden loss of blood causes less oxygen to reach the brain, which can lead to unconsciousness and ultimately death.
For centuries, physicians have stemmed bleeding by compression, pressing on the wound with the hand and or using bandages.
Bandages have been used throughout history and most first aiders nowadays are trained to use bandages effectively. The calm and prompt use of compression on a wound has and will continue to save many lives.
In an emergency situation the principles Airway, Breathing and Circulation (ABC) are paramount. Bleeding is the C and should be attended to once the airway and breathing is secure.
Wounds can swell, leading to severe bruising and blood loss into the surrounding tissue.
When a person loses over 15% of the circulating blood volume, symptoms may occur. With a loss of between 15-30% a person will become pale, sweaty, will have an increased pulse rate, and a low blood pressure. This is a critical stage if further deterioration is to be prevented. It is crucial to stem the flow of blood promptly.
The body’s natural trauma response is to shut down in order to preserve the function of the brain. Lying the patient down and compressing the wound will have an instant positive effect.
Many injuries occur in the workplace despite the best preventative measures. Commonly, falls and slips, many include moving machinery and parts. The outcome of such injuries depend on the skill and speed of the first aider present.
Bandaging and compression are the primary treatments for cuts and bleeding wounds.
The scalp is a particularly vascular area and even surface cuts and abrasions can cause a serious amount of haemorrhage.
It is well known that even “trivial” lacerations of blood-rich areas such as the scalp may bleed profusely and persistently.
Bandaging has its clear drawbacks. It takes time to bandage correctly and often requires two people to effectively bind the wound and apply compression.
Head bandaging is particularly difficult and time consuming in a pressured environment. Bandages can draw blood from the wound and inadequate compression can allow the bleeding to continue.
Haemocap multisite™ a product from Haemoconcepts Ltd is an innovative patented wound binder which can be easily applied by first aiders. It has been designed to be applied quickly to virtually any part of the body, saving time and vitally reducing blood loss. It can be applied by one personnel freeing them to perform other duties if necessary. It delivers 50 mmHg when activated causing adequate compression for haemostasis. Once applied the device can be deactivated to inspect the wound and if necessary re-applied. It is transparent and disposable and needs little or no training, easily stored and is currently being used by the NHS. Having Haemocap in the workplace will ultimately enhance the effectiveness of the first aider and reduce the dire consequences that are associated with bleeding.
