What the count covers

368 NPPES records list certified respiratory therapist (227800000X) as their primary taxonomy with a practice address in California: 0.9 per 100,000 residents against 0.5 nationally (50 states and D.C.). Los Angeles has 55 of them (15%).

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
