Angela,
COPD is a terrible disease. For many years, I worked for a company that specialized in taking care of patients with COPD. On the cost of the concentrator; part of the cost of the machine involves the supplies that must be changed at least every week or two to reduce the chance of infection. External filters need to be cleaned weekly. Additionally, the machine needs servicing about every 1000 hours, which involves disassembly and "flushing" or changing the siev beds. Also, part of the monthly rate should cover visits by a respiratory therapist to asses his condition and communicate with his pulmonoligist to make any changes in his treatments.
The costs for a vehicle, the therapist, the technician, the liability insurance, the billing person, the business licenses, the supplies etc. are what contributes to the monthly cost. Also, there are portable tanks that need to be on hand for power outages and travel. All that being said, $250 a month is a little more than the average that Medicare pays but it is not absurd.

One more thing, to properly help your father better manage his disease, fully explore his diet. Foods high in starch and fat should be avoided..as should milk and orange juice. These foods help create excess mucus that further constricts the bronchial tubes and inhibits proper gas exchange. Does he by chance have Emphysema also?
