CPAP equipment can deliver pressures other than those intended for many reasons. Usually inaccurate pressures are errors on the low side, usually resulting in the user's return of symptoms. Particularly if the prescription is some years old, I have found many CPAP units which were brought with patients on the night of their retitration study to be delivering pressures as much as three cm lower than they should be. It's certainly worthwhile to be curious about this, especially if you are seeing a loss of effectiveness. Checking the pressure by analog device is easy and should be cheap, actually a free service of your DME. Equipment newly provided by the DME can also be incorrectly set up or defective. This I have seen as well, and I recall a patient who struggled for over a month to be compliant with therapy, to find, upon returning to the sleep lab, that his unit was delivering at an initial ramp level of 4 cm (ramp not prescribed), and not ramping up to the prescribed level of 9 cm. No wonder the poor fellow couldn't sleep!
