Field dressings and pressure dressings are two types of bandages that are used to stop bleeding and prevent infection in wounds. They have different purposes and applications, depending on the type and location of the wound.
Field dressing
A field dressing is a kind of bandage that is intended to be carried by soldiers for immediate use in case of (typically gunshot) wounds. It consists of a large pad of absorbent cloth, attached to the middle of a strip of thin fabric used to bind the pad in place. Field dressings are issued in sealed waterproof pouches to keep them clean and dry; the pouch can be torn open when required.
The main function of a field dressing is to cover the wound and apply direct pressure to stop the bleeding. The pad should be placed over the wound, and the strip should be wrapped around the injured body part and tied securely. The dressing should not be removed or changed until medical help is available, unless it becomes soaked with blood or pus.
Pressure dressing
A pressure dressing is a type of bandage that is used to apply constant pressure to a wound, usually on an arm or leg, to control bleeding and prevent swelling. A pressure dressing consists of a sterile gauze pad, covered by a layer of elastic bandage that is wrapped tightly around the wound site. The pressure dressing should be checked regularly for signs of circulation, such as pulse, color, and temperature of the skin.
The main function of a pressure dressing is to compress the blood vessels and reduce blood loss. A pressure dressing can also prevent fluids from collecting in the tissue, which can cause infection or tissue damage. A pressure dressing can be used in conjunction with a field dressing, by placing the gauze pad over the field dressing and wrapping the elastic bandage around it.
Which statement is correct?
Below are some statements related to field dressings and pressure dressings. Which one is correct?
- A) A field dressing can be applied to any wound which is bleeding heavily. If the wound is on an arm or leg, a pressure dressing can also be applied.
- B) A field dressing and a pressure dressing are interchangeable terms for the same type of bandage.
- C) A field dressing is used to seal a “sucking” chest wound, while a pressure dressing is used to treat burns and skin grafts.
- D) A field dressing is used to cover a wound and prevent infection, while a pressure dressing is used to stop bleeding and reduce swelling.
The correct answer is A. A field dressing can be applied to any wound which is bleeding heavily. If the wound is on an arm or leg, a pressure dressing can also be applied.
The other statements are incorrect for the following reasons:
- B) A field dressing and a pressure dressing are not interchangeable terms for the same type of bandage. They have different structures, functions, and applications.
- C) A field dressing is not used to seal a “sucking” chest wound, while a pressure dressing is not used to treat burns and skin grafts. A “sucking” chest wound is a type of wound that allows air to enter the chest cavity through an opening in the chest wall, causing breathing difficulties and lung collapse. A field dressing can make this condition worse by trapping air inside the chest. Instead, a waterproof wrapper of a field dressing can be placed over the hole, with the clean inside against the wound, and taped in place on three sides, leaving the bottom edge free. This creates a simple flapper valve that prevents air from entering but allows it to exit. Burns and skin grafts are treated with special dressings that protect the skin from infection and promote healing. Pressure dressings are not suitable for these types of wounds, as they can cause further damage or interfere with blood supply.
- D) A field dressing is not only used to cover a wound and prevent infection, but also to stop bleeding by applying direct pressure. A pressure dressing is not only used to stop bleeding and reduce swelling, but also to prevent fluid accumulation and infection by compressing the tissue.
Conclusion
Field dressings and pressure dressings are two types of bandages that are commonly used in emergency situations to treat wounds. They have different purposes and applications, depending on the type and location of the wound. It is important to know how to use them correctly and safely, as they can save lives or prevent complications.
