Which statement is not listed as a diathermy effect on blood and fluid dynamics?

• A. Increase blood flow
• B. Increase capillary pressure
• C. Increase capillary growth
• D. Decrease blood flow

Answer: (D)

The effect being tested is how diathermy influences local blood flow and fluid dynamics. Heating tissue from diathermy causes vasodilation, so more blood flows into the heated area. That increased perfusion raises capillary hydrostatic pressure and promotes greater exchange of fluids across the capillary walls. Over time, the enhanced metabolic activity and signaling in warmer tissue can support angiogenesis, or capillary growth. Because all these effects point toward increased, not decreased, blood flow and capillary activity, a statement about decreasing blood flow does not fit with the typical diathermy response.
