I am currently tracking AHI via my CPAP and ODI via a recording oximiter. I have found that, in some cases, my AHI trends upwards as my ODI trends down with increased pressure. This is almost entirely due to more recorded hypopneas by the CPAP machine. Apneas are almost completely gone.
Has anyone else encountered this? having pretty good Oximeter readings with AHI often over 5 and sometimes not so good Oximeter readings when AHI is less than 5?
Am trying to figure out what is going on here, but suspect that the CPAP machine is not so accurate and maybe sensitive to pressure and/or leaks, causing it to register more hypopneas than actually present. Guessing the oximiter is more accurate (SPO 7500).
If anyone cares to comment, I'd really like to hear it so I can try to sort through this.
