During continuous ultrasound, what should be done to intensity to minimize tissue damage?

During continuous ultrasound, what should be done to intensity to minimize tissue damage?

• A. Lower it
• B. Increase it
• C. Maintain a high level
• D. Apply intermittently

Answer: (A)

Continuous ultrasound delivers energy without a break, so tissue heating accumulates over time. Heating rises with intensity, making tissue damage more likely if the intensity is too high. To minimize risk while still delivering therapy, use the lowest intensity that achieves the desired effect. Increasing or maintaining a high intensity would increase heating and danger, and applying intermittently would switch you to pulsed ultrasound rather than true continuous mode.
