Fisher and Paykel built a large facility to manufacture respiratory equipment a little over a year ago. I really wanted to visit the factory, especially as I am very interested in their new Pilairo, which is not yet available in the US. A call to their factory revealed that they do not allow customers on the premises, whether end users or DMEs. They do sell to US DME customers, but all those sales are handled by their Irvine, CA office, which is where the output from the factory is shipped.
As for DMEs, there are none in Tijuana, or apparently anywhere in Mexico. The system is very different from the US. There are sleep doctors who perform sleep studies, but after diagnosis the doctor sells the equipment directly. Thus there is no need for the DME at all.
Sleep apnea is not covered by the the basic national health plan, although it may be covered by some state health plans (but not Baja California Norte). There is a second layer of national health that provides additional benefits to employed people, but apparently it does not cover sleep apnea either. Private health insurance doesn't really exist. Consider as well that MN$40 an hour is a really good wage (about US$3). That's not much if you have to pay for your sleep apnea therapy out of pocket.
As a result, in all of Tijuana (pop. 1.3 million) I was able to find only two sleep doctors, who operate a sleep clinic together. I went to the clinic hoping to find some masks to buy, but they sold only three masks; one a nasal pillow mask, another that was a regular nasal mask, and one full-face mask, at a price of about $70 each. Those are your choices if you have sleep apnea in Tijuana, unless you buy online or go up to San Diego. And online or San Diego suppliers will require a prescription from a US doctor. Also, I showed the people at the clinic my box of Provent tabs and they had never seen them. They also sell CPAP machines, but the prices were roughly the same as our online suppliers. During my visit I talked to the staff, not the actual doctors.
So I came back without any new sleep apnea stuff. All I brought back was a sadness for the state of sleep apnea therapy in Mexico. Now I'm curious about how it works in other underdeveloped places.
