Frequently Asked Questions
How long and how often should I use a cold therapy machine after surgery?
Most clinicians recommend 15–30 minute sessions every 2–3 hours during the first 72 hours, tapering frequency as swelling improves—always follow your surgeon's protocol.
Can I use heat and cold with the same device?
Some smart units, like dual-mode models, offer both heat and cold; alternating can ease stiffness, but get guidance from your provider on timing and duration.
Are these devices safe for diabetics or people with poor circulation?
People with peripheral neuropathy, diabetes, or compromised circulation should consult their clinician before using cold/compression devices due to risk of tissue injury.
Do I need to use ice in the reservoir?
Many machines circulate cold water or ice; check manufacturer instructions—larger reservoirs need more ice initially, but some units are designed for extended cycles with minimal refills.
Are cold therapy machines covered by insurance?
Some models are FSA/HSA eligible and may be reimbursable with a clinician's prescription—keep receipts and product codes for claims.
How do I clean and maintain a cold therapy machine?
Empty and dry the reservoir after use, wipe pads with mild soap and water, and follow manufacturer instructions for filter or pump maintenance to prevent mold and ensure longevity.
