I'd like to know too and which models are in fact accurate that record your O2 saturation during the night.
I recently was in the hospital for a diagnostic procedure and my O2 levels dipped enough that they put me on oxygen which helped immensely to get my levels to 97-98%.
SleepyHead is currently compatible with Contec CMS50D+, CMS50E, CMS50F and CMS50I serial oximeters.
(Note: Direct importing from bluetooth models is probaby not possible yet)
You may wish to note, other companies, such as Pulox, simply rebadge Contec CMS50's under new names, such as the Pulox PO-200, PO-300, PO-400. These should also work.
It also can read from ChoiceMMed MD300W1 oximeter .dat files.
I believe they are all sufficiently accurate, the technology is not rocket science.

All the models, "F" and greater, use the same mini USB port for data download, charging and for the finger probe. The bluetooth versions allow for real-time data monitoring while you're using the CMS-50. It would seem that the bluetooth option is better suited for a medical office and not a CPAP user. My bluetooth "I" model is a neat idea that I played with exactly once. For our needs with a CPAP, this option serves no purpose. There was a 3 dollar difference when I bought mine, so I dared to go wild with my money.

There is usually a 20-30 second lag between when we breathe, versus when the oxygen-enriched blood reaches the pulse oximeter. The newly-oxygenated blood flows first to the heart and to the brain, and later to external limbs and fingers.
When we hold our breath, we usually (perhaps unconsciously) take a deeper breath first.
Perhaps about 20 to 30 seconds later (around the time when we are starting to feel starved for air) the extra Oxygen from the deeper breath may reach the pulse oximeter, briefly causing it to show higher SpO2?
And as we start breathing rapidly again to regain our breath, perhaps the oxygen-deprived blood is finally reaching the pulse oximeter, briefly causing it to show lower SpO2?
Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.
CMS50F works well enough, the software is very basic but it does work.
@raisedfist, can you elaborate on what you mean by "basic"?
