What type of pressure do short-stretch bandages exert when they are applied correctly?

1. Low resting pressure and low working pressure

2. High resting pressure and high working pressure

3. Low resting pressure and high working pressure

4. High resting pressure and low working pressure

The correct answer is: Low resting pressure and high working pressure

Short-stretch bandages are designed to provide a specific type of compression that is beneficial in managing conditions such as lymphedema. When these bandages are applied correctly, they exert low resting pressure, meaning that when the muscle is relaxed, there is a minimal amount of pressure applied. This characteristic is particularly important because it allows for effective lymphatic drainage without restricting circulation or causing discomfort during rest. When the muscles are active, short-stretch bandages increase the pressure, resulting in high working pressure. This means that the pressure exerted by the bandages increases significantly during muscle contractions. This is crucial as it helps to promote venous return and lymphatic drainage when muscles are engaged, facilitating movement of lymph fluid and reducing swelling. Using short-stretch bandages effectively allows for a dynamic compression system that responds to the body’s movements, making it an ideal choice for managing conditions that involve edema. Thus, short-stretch bandages are ideal for providing a combination of low resting pressure, which supports comfort, and high working pressure, which enhances functionality during activity.
