The complexion of the home oxygen market is changing. Home oxygen markets have been predicated on a dealer infrastructure. These dealers get reimbursed for regular deliveries of liquid oxygen used for supplemental oxygen so the patient can go out, buy groceries, go to the movies, and visit family for a short time. The advent of reliable, inexpensive portable home oxygen concentrators has changed the market dynamic significantly.

No longer do patients need regular deliveries of liquid oxygen for supplemental purposes so the patient can go out. Now, the patient just uses one device at home and while out of the home. The economics of the medical oxygen market have been changing for a long time. CMS Medicare and the private insurers that follow their lead have been resisting paying for supplemental liquid oxygen because the price of truck rolls is too high. With lowered reimbursement, the dealer distribution network that has been in place for many years is no longer tenable.
