Can you sell a used CPAP machine on eBay?

Prescription onlyNo, not on eBay.

eBay's medical devices policy names this device type as prohibited, whatever the model.

eBay's medical devices policy lists CPAP machines among the prescription device types that can't be sold on eBay, whatever the brand or model.

eBay doesn't allow any medical device that requires a prescription. Whether a particular CPAP machine does depends on how its maker registered it with the FDA, and that is printed on the device: look for "Rx only" or "Caution: Federal law restricts this device to sale by or on the order of a physician" on the label.
