Final answer:
For an open neck injury, it is important to quickly apply a sterile dressing without probing or applying pressure if arterial damage is suspected. Secure it with bandages, add more layers if necessary, and call for emergency medical assistance without attempting to provide in-depth care if not trained.
Step-by-step explanation:
In the event of an open neck injury, it is crucial to take immediate action and apply the proper dressing. To reduce the risk of further injury or infection, sterile dressings should be used. It is important to apply pressure gently to control bleeding if arterial damage has not been confirmed. Do not probe the wound or apply pressure if you suspect damage to the airway, major blood vessels, or if an object is impaled in the wound.
First, wash your hands and put on gloves, if available, to prevent contamination. Apply a sterile dressing to the wound and secure it with bandages without putting pressure on the injury site. If blood soaks through, do not remove the initial dressing; instead, add more layers. If bleeding is severe and you have been trained to do so, you may apply direct pressure around the area or use a tourniquet, but only as a last resort when direct pressure is not applicable and medical help is delayed.
Keep the injured person calm and call for emergency medical assistance immediately. Never attempt to provide this type of aid if you are not trained, as doing so could cause more harm. Leave all in-depth care to medical professionals.
