What duration is typical for cold pack cryotherapy?

• A. 5-10 mins
• B. 15-20 mins
• C. 25-30 mins
• D. 40-60 mins

Answer: (B)

Cold pack cryotherapy is kept around 15 to 20 minutes because this window provides enough cooling to reduce pain and swelling by slowing nerve conduction and lowering tissue metabolism, while avoiding risks from prolonged exposure. Staying within this time frame helps achieve analgesia and edema control without risking skin or tissue injury, such as frostbite or nerve damage, that becomes more likely with longer applications. If the area is large, the patient has reduced sensation, or tolerance is low, shorten the time and monitor closely, using intermittent applications as needed.
