Strange air flow graphs in SleepyHead

Post by ragnar33 » Fri Apr 17, 2015 11:33 am

Hello, for several nights there is missing airflow data for part of the night. All the other data appears normal so I am puzzled as to the reason. I am guessing that the fault is in the CPAP, a four year old Philips Respironics System One. It is not humidifying either BTW.
The oximeter data shows good results so obviously I am breathing (:-)).
This is what I see:

This happened three nights, now the report is normal again.

I don't have an answer for you but my husband's PR 760 also had one night with gaps in his flow graph. His machine has very few hours on it. So, I'm interested in seeing if anyone has any ideas he didn't have SpO2 readings so I was a little concerned the next night. He didn't report any different sleep and it hasn't happened again.

Thank you OkyDoky, at least I am not the only one seeing this.
