02 levels down

[kyork]

HI,
    I tried using an O2 monitor on my finger the other night.   Several times the alarm woke me up because the levels had gone below 90%.  Is this normal?   I have noticed the air is somewhat forceful coming out.   Using Resmed s9 and a p10 nasal pillow.  Maybe the settings were changed?

If your Resmed S9 has data capabilities then you could probably correlate events of desaturation with apnea or flow limitation on the xPAP data. Since your profile does not identify a machine model or settings, it's not possible to guess. Let us know if you want to take this to the next level. We can help you identify the machine, settings and get setup with software.
