If continuous ultrasound is used, water should be what temperature?

• A. Cold
• B. Warm
• C. Hot
• D. Room temperature

Answer: (B)

Continuous ultrasound delivers heat to tissues, so when you use a water bath as the coupling medium, the water temperature becomes part of the therapeutic effect. Warm water allows a safe, comfortable level of heating that helps raise tissue temperature without risking burns. Cold water would limit heating and feel uncomfortable, while hot water could cause burns. Room temperature water wouldn’t provide as much heating as needed for thermal effects. For underwater continuous ultrasound, warm water—typically around body temperature or slightly warmer (about 35–40°C, roughly 37°C)—is used to achieve effective heating safely.
