When the chest infection cleared up, I no longer had symptoms, but started CPAP treatment at the direction of the lab and my doc.

My AHI is under 5 every night .. . currently averaging about 2.9.

Is this low AHI from CPAP treatment, or because I was symptomatic only during illness?

You should have gone through a titration sleep study to determine how to setup your machine (and if it would help) if so, then I assume your question is whether that study was negatively influenced by your chest infection and the doctor didn't notice? Well, it's possible, if that happened you need a new doctor. Personally I would give the doctor the benefit of the doubt and assume they took it into consideration. If you don't think so, then I would recommend a new sleep study to verify you need the CPAP machine.

When you are able, filled out your profile, machine, mask, pressure, etc.
How long have you been on Cpap?

This can be the result of an upper respiratory infection that causes nasal congestion, along with swelling of the throat, or tonsillitis that temporarily produces very enlarged tonsils. The Epstein-Barr virus, for example, is known to be able to dramatically increase the size of lymphoid tissue during acute infection, and OSA is fairly common in acute cases of severe infectious mononucleosis. Temporary spells of OSA syndrome may also occur in individuals who are under the influence of a drug (such as alcohol) that may relax their body tone excessively and interfere with normal arousal from sleep mechanisms.

The low AHI is because you are now using CPAP.

Yes, the chest infection could have made the OSA a bit worse. But a chest infection is not going to cause a person with NORMAL sleep to all of a sudden have an AHI of 38. My guess is that at best your natural OSA is well into the moderate range (15-30 events per hour.) And it could well be severe (over 30 events per hour). The CPAP is what's giving you the nice low AHI right now.
