A pressure dressing, also known as a pressure bandage, is a bandage specifically designed to apply pressure to a particular area of the body. According to the reference, these bandages typically lack adhesive and are applied over a wound that has already been covered with an absorbent layer.
Key Characteristics of a Pressure Dressing
Here's a breakdown of the key characteristics:
- Purpose: To apply pressure to a specific body area.
- Application: Applied over a wound that is first covered with an absorbent material.
- Adhesive: Generally, pressure bandages do not have adhesive.
Why Use a Pressure Dressing?
Pressure dressings serve several important functions:
- Control Bleeding: The applied pressure helps to slow down or stop bleeding.
- Reduce Swelling: By compressing the area, it can minimize swelling.
- Support Injuries: Can provide support to sprains, strains, and other injuries.
Example Scenario
Imagine you have a cut on your arm. You would first clean the wound and apply a sterile, absorbent pad. Then, you would wrap a pressure bandage around the pad and the surrounding area to apply consistent pressure. This would help stop the bleeding and reduce the risk of swelling.
