They went too extreme. Maybe let people buy the device but it still needs to be manufactured to regulations.
However I don’t know enough about CPAP to judge whether you should need a doctors cert or some kind of training cert on the device. Can a CPAP harm you if you incorrectly use it / use incorrect settings?
If a CPAP just did nothing, the users would be harmed. That's why they're using a CPAP machine in the first place. Or do you mean can the wrong settings be even more harmful?
