What is a common effect of pump therapy when treating lymphedema?

1. Promotes rapid healing of ulcerations

2. Can cause tissue damage

3. Encourages natural fluid drainage

4. Reduces the need for manual massage

The correct answer is: Can cause tissue damage

Pump therapy is often used in the management of lymphedema, and while it can have beneficial effects, one common concern is the potential for tissue damage. This can occur if the pressure settings of the pump are too high or if the therapy is not applied correctly, leading to excessive compression on the tissues. Tissue damage may manifest as skin irritations, necrosis, or exacerbation of the lymphedema if proper precautions are not taken. It is crucial for practitioners to monitor the patient's skin integrity and adjust the therapy to minimize these risks. In contrast, the other options imply positive benefits or functions of pump therapy that may not be universally recognized or applicable. For example, while pump therapy can aid in lymph fluid movement, it does not necessarily promote rapid healing of ulcerations on its own, nor does it eliminate the need for manual massage entirely. Manual lymph drainage can still play a significant role in treatment. Additionally, while pump therapy encourages fluid drainage to some extent, the risk of tissue damage highlights the necessity for careful application.
