On the machine I have (ResMed AirSense 10) the data gets written to an SD card I can pull out and import into OSCAR to see what the machine detected about my sleep apnea events.
I also (not always, but when I'm testing changes) use a continuous pulse oximeter to test my SpO2 blood oxygen % over the entire night. The data from this can either be combined with the data from the CPAP machine, or used on its own to test things like how I do with the collar and no CPAP machine, since the SpO2 drops are the dangerous thing I'm trying to avoid by eliminating the apnea events.
I use the Wellue SleepU for SpO2 monitoring but there are a lot of similar devices (the kind with finger tip sensors are generally more accurate than the wristwatch based solutions).
Most CPAP machines including the one I have record a lot of data that can be analyzed via software like OSCAR:
