What is the recommended hydrocollator temperature range for effective heat therapy?

• A. 148-156
• B. 158-167
• C. 170-180
• D. 190-200

Answer: (B)

Thermotherapy with a hydrocollator aims to raise tissue temperature enough to improve blood flow, tissue elasticity, and pain relief without causing skin damage. The best range for this is about 158–167°F (70–75°C). This temperature is high enough to penetrate and produce therapeutic effects but stays below levels that markedly increase burn risk, especially if the pack is left on too long or the patient's skin sensation is reduced. Temperatures well below this range may not provide sufficient heating for deeper tissues, while hotter ranges (above 167°F) raise the chance of burns. For safe use, always check the pack temperature on a nonerogenous area, wrap it in a towel, and monitor the patient during treatment.
