Some CPAP machines are crippled by the manufacturers for marketing reasons. Same hardware can cost a cpl hundred or thousands depending on if they have a feature turned on.
It would be like buying a V8 with only 4 active cylinders. You have a V8. Manufacturer cripples the ECM so that only 4 cylinders fire.
Should you be allowed to put in an aftermarket ECM that allows all 8 to fire?
This isnt about repair at all in the medical arena.
With farm equipment it is and Apple products it is. With the medical device manufacturers it is about removing their hardware crippling via software.
Tesla does the same thing to their cars. You can get a horsepower upgrade over the internet with a $10K software upgrade.
