The difference is that the trilogy can be more finely tuned to the individual using it than a bi-pap machine. They do essentially the same thing: provide pressure on both the inhale and the exhale. The major thing they do is blow off accumulated CO2.

Trilogy is an at home vent. I use it when I sleep. It helps keep the gases down in the oxgen and helps keep the airway open. I have been on it almost a year now.

Thanks

@Ladyfi1958 Sorry to hear of this. What type of machines? Have you tried a strict diet and exercise?
