Discharge Instructions: Using a Cold Water Therapy Device
Your doctor prescribed a cold water therapy device. This device helps reduce pain and swelling and aids recovery. It maintains a constant and precise temperature, providing up to several hours of continuous cold water therapy. Here’s what you need to know about home care.
Home care
Recommendations for home care include the following:
-
Use the cold water therapy device as directed by your doctor. They will tell you how many hours a day you should use it. Follow all instructions on the manufacturer's guide.
-
Fill the device with the recommended amount of ice and water.
-
Apply the pad to the area of your body that is injured. Do not apply directly to your skin. Use a cloth between the pad and your skin. Don’t wrap the area too tightly. Firm pressure is enough.
-
Press the hand pump several times as directed. You will feel cold water fill the pad. Some newer devices have an electronic pump and don't need a hand pump.
-
Pump again whenever the pad starts to feel warm (15 to 20 minutes). You can continuously circulate the cold water from the cooler. Some newer devices automatically circulate the cold water. They don't need manual pumping. Most devices can provide several hours of cold therapy.
-
Check your skin under the wrap often, and keep your skin dry.
