“For a lot of people out there, the C.P.A.P. machine turns into a doorstop,” said Dr. Joseph Golish, the former chief of sleep medicine at the Cleveland Clinic. “C.P.A.P. is very effective in the sleep lab. But when people go home, there’s a good chance they won’t use it, and the success rate of an unused C.P.A.P. machine is absolutely zero.”
Now an alternative form of C.P.A.P. is gaining popularity: a patch that fits over the nostrils. Called Provent, the patch holds two small plugs, one for each nostril, that create just enough air pressure to keep the airways open at night. It is far less intrusive than the traditional C.P.A.P. machine. It is also more expensive, and it doesn’t work for every patient.
