Proper application of a cold compress is crucial for its effectiveness. Here are the steps: 1. Prepare the Compress: Use a cold pack, or wrap ice cubes in a towel. Avoid placing ice directly on the skin to prevent frostbite. 2. Apply to Affected Area: Place the compress on the targeted area for about 15-20 minutes. 3. Monitor the Patient: Check the skin under the compress every few minutes to ensure there is no damage. 4. Repeat as Necessary: Allow the skin to return to normal temperature before reapplying, typically waiting about 45 minutes to an hour.
