Final answer:
The preferred first-aid treatment for a person with a badly bleeding forearm is to apply direct pressure with a clean cloth, elevate the limb, and keep the person calm. If trained, and necessary, a tourniquet might be used as a last resort. It is also essential for the rescuer to wear gloves for safety.
Step-by-step explanation:
First-Aid Treatment for a Badly Bleeding Forearm
The preferred first-aid treatment for a person with a badly bleeding forearm involves a sequence of steps to control the bleeding and minimize the risk of further injury or infection. Initially, the injured person should be made comfortable and any dangers should be removed from the surrounding area. If it is safe to do so, gloves should be worn by the rescuer to prevent contamination.
The first step in managing severe bleeding is to apply direct pressure to the wound with a clean cloth or bandage. Direct pressure helps to control bleeding by compressing the blood vessels at the site of injury. If blood soaks through the cloth or bandage, another should be placed on top without removing the first, to avoid disturbing any blood clots that may have started to form.
If direct pressure is not enough to stop the bleeding, and if the rescuer is trained to do so, an arm tourniquet may be considered. However, this should only be used as a last resort and if proper training has been received, as improper use can lead to further injury. The injured arm should be kept elevated above the heart level, as this can help reduce bleeding. Finally, the person should be kept still and calm while waiting for emergency medical services to arrive.
