Why is polarity important in HVPC for wound healing?

• A. Polarity is not important
• B. Polarity changes frequency
• C. Polarity guides edema management and tissue repair
• D. Polarity changes color of device

Answer: (C)

Polarity in HVPC shapes the wound environment and how healing cells respond. The electric field created by a specific polarity drives ion flow and local chemistry at the wound bed, which in turn influences key cells involved in repair—such as fibroblasts, keratinocytes, and immune cells—and helps manage edema by affecting fluid movement and capillary behavior. Because these processes steer both swelling control and tissue regeneration, choosing the appropriate polarity supports edema reduction and tissue repair, making that option the best description of why polarity matters. It isn’t about changing frequency or color of the device, and polarity is indeed an important factor in HVPC wound care.
