Rescan flow rate graph interpretation

[Charlie Sue]

Hi, all! I am preparing for my doc visit tomorrow and am looking at my data in Rescan, which I usually ignore in favor of sleepyhead. Can anyone tell me what I am seeing here? No events around this time at all.

Thanks.

That's not flow. It's flow limitation. Flow limitation is a scoring on a 0 to 1 scale of the shape of the inhalation waveform.
Note the little waveform pictures on the left axis. When the inhalation waveform "flat-tops" it indicates flow limitation.
The Autoset should raise pressure on flow limitation.

Hmmm.. kind of looks like it could be your pressure graph, esp: since your pressure is fairly low and close..(7-10). It would probably jump up and down that much since your pressure is that low and the setting is only 3 apart. . That's fairly low for apnea settings, but as a newbee to CPAP ya gotta start somewhere. Good Luck tomorrow..

I think Mongo's on the right track. That's the flow limitation chart. From Resmed's site: The S9 AutoSet responds to flow limitation to pre-emptively treat apnea events and prevent more serious, subsequent events from occurring.

Hi Charlie Sue,
Good luck to you at your Dr. appointment, tomorrow.

justMongo is right !
