I had my DPS put in a year ago. My doctor made it very clear to me that a DPS can delay the need for full ventalation for hopefully up 16 months maybe longer if you are responding well to it. Be careful what you read talk to your doctor ask questions be informed of what the expectations are.

It's an old article, but Patrick I think it is quite correct?
The headline sounds a bit bold, but it states clearly that it can help breathing for longer until a ventilator is needed, it doesn't in any way make it sound as though it replaces a vent.
