PFO is actually the measurement from the little O2 looking cannula in your nose in both a PSG and EEG, the CPAP mask takes the place of the reading.deltadave wrote:I'd love to see them.JohnO wrote:I actually don't see a count on the report.

The NPSG desaturation(s) above are atypical (ya THINK?) of OSA.
If it isn't a PFO (BTW, PFOs in OSA patients are frequent) then it could be poor signal quality that should have been addressed at the time of acquisition.

Not even.

Thanks John - I especially appreciate your early info early on regarding option in the Twin Cities.jweeks wrote:Congrats on being off an running on such a great start.

Re: My Sleep Study Report + 14 Days on the Hose!
Here are two summary strip charts from a CMS-50E. I recorded about 6 weeks of data prior to my sleep study and subsequent acquisition of an auto-CPAP machine. I've recorded about 5 nights since.deltadave wrote:I'd love to see them.JohnO wrote:From my pre-CPAP and post-CPAP SpO2 monitoring, a typical night before CPAP would have more than 200 desaturation events.

The "before" strip is a pretty typical example.

So is the "after" strip.

Re: My Sleep Study Report + 14 Days on the Hose!
Given your data, it would appear more likely that the baseline drop during NPSG was due to equipment issues (inadequate sensor signal, reduced circulation from sleeping on arm, etc.):

At any rate, I would have expected the technician to intervene to attempt to improve signal quality.
