bought used CPAP

Hi. I have sleep apnea without any doubt. But my insurance won't cover the sleep lab. So I found a brand new Cpap at a garage sale and I use it nightly. I just left it set for the setting it was on and it seems to work fine -- Any concerns or advice?

Thanks

What brand and model did you buy? We might be able to help you tweak your pressures if your machine is data capable.

Congratulations. I would ask if it's a data capable machine and can you check you nightly numbers to be sure it's working for you. Or can you get the software to check out your numbers. Do you know what pressure you're on?
Please take the time to fill out your profile (text, not pictures) so we can read what you're using and give better advice.

Good for you, dwhite, for being proactive about your health.

Assuming that plain vanilla OSA is really what a person has....

Even if a garage sale machine isn't capable of recording AHI and Leak data ("full" data) a person with OSA can still get good treatment with a plain, basic CPAP. Full data would be icing on the cake and make tweaking the pressure easier, but titrating yourself (coming up with the right "dosage" of pressure) can certainly be done with a simple CPAP machine too:

Link to a study that concluded, "yes."
"Can Patients with Obstructive Sleep Apnea Titrate Their Own Continuous Positive Airway Pressure?"

As soon as you post the full name of your machine -- brand and model name -- I'll bet you'll be able to find the clinical manual for the machine in short order.
