Which device is more effective in decreasing skin temperature during cryotherapy?

• A. Microwaveable pack
• B. Chemical spray
• C. Ice pack
• D. Fan

Answer: (C)

Lowering skin temperature effectively in cryotherapy comes from placing a cold mass in direct contact with the skin so heat can flow from the body into the mass, with ice providing a strong, sustained cooling due to its freezing point and latent heat absorption. An ice pack stays near 0°C and remains in contact with the skin, so heat transfer is continuous and the surface temperature drops more reliably and deeply than other options. A microwaveable pack is usually warm, which would raise rather than lower skin temperature. A chemical spray can produce quick surface cooling but is often less consistent and can be harder to control. A fan cools only the surrounding air and doesn’t remove heat from the tissue effectively through contact. For these reasons, an ice pack is the most effective device for decreasing skin temperature during cryotherapy. Remember to use a barrier between skin and ice to prevent frostbite and to monitor the skin response during treatment.
