SPO2 & Sleep Stages

Hello! First time poster here.


Quick Facts:
Machine: Still waiting for my Dreamstation replacement. For now I have a cheap machine, Apex XT FIT (Not capable of storing data)
Mask: Using both Dreamware nasal and full-face mask. I have tried a handful of nasal masks.
Monitoring equipment: Using both Garmin Venu & The Wellvue 02 Ring
Pressure: 7
Diagnosis - mild/moderate apnea


I have been monitoring my sleep using the two devices mentioned above. I am limited while using this machine since it does not store data.
The results I am getting are a bit concerning and wondering if this is normal or far from an acceptable CPAP treatment.

-REM & Deep Sleep
On Average, I am getting about 1.5 hours in each of these two stages

-SPO2 Drops (this is my greater concern)
I am averaging about 7 drops per hour (anything below 90%)
The lowest Spo2 drop per night is usually between 79-82 but most are in the high 80s.

Does Spo2 typically drop like this if the CPAP is working properly? If not, what would you recommend?

Hello first timer,
Am I correct that you are asking two different questions?
#1) is 1.5 hours each in REM and deep sleep adequate
and
#2) Are saturations that you describe (nadir 79-82) but most often desaturations to high 80s to be expected with a properly functioning and titrated CPAP.

Without knowing your untreated or basal nocturnal saturation level, it's hard to tell. While most adults have a nocturnal 02 in the 95+ range, some will have 02 levels in the low 90s as a result of other varying medical compromises.

I would be helpful to know what your oximeter shows prior to any obstructions, central apneas or hypopneas
