I don't know how anyone can afford to get sick today they have u paying so much for all this equipment its out of hand some of these drugs are very expensive just your co pay alone ,I use a home vent called trilogy which is a vent for trachea use but also has multi uses for sleep apnea and carbon retention which is the reason I can't go with a different type unit this is alarmed and will tell if u slip in to disconnect or other and Simon oxygen 24/7 so it has to be able to do that with a humidifier if u need it ,no longer on trachea had that out several months ago and this is working fine. ,but the co pay is 170. Per mo. Just for that plus I have two oxygen condensors and one home fill ,that I'd around 78 per,mo. Now if u look at meds and add in what I pay for my insurance and the part D wow it's over 113 .mo. plus 100. Past D .add them all together it comes out 611 00 per mo. With meds it's just got out of hand crazy ,
