Zero AHI+no graph in Sleepyhead
#1
Zero AHI+no graph in Sleepyhead
I have been using a ResMed S9 since January 14. My AHI readings have been averaging 0.56 for the past 7 days. Last two days the daily average has been zero. I like that number and am not complaining. However I am curious why there is not a graph for those zero nights. Is that normal?
Cheers, Vegaspier

RE: Zero AHI+no graph in Sleepyhead
I don,t use SH
an apnea is scored when there is reduction in breathing for at least 10 seconds
less than 10 seconds are not scored/shown on the graph (AHI reset each hour) but can be picked up if you zoom on the flow graph
flow limitation is partial upper airways obstructions, on Resscan shown by mountain shape. the flatter shape the worst is the obstruction

No, it's not normal. There should be graphs, leak data, and so forth even if
there were no events and a zero AHI.

Remove the card from the machine. Unplug the machine from the wall. Wait a minute. Plug back in. Put the card back in. Wait a minute or so. Then take out the card and see if it now has data. It will have incomplete data but there will be some like AHI and flow rate.

S9s have a habit of doing all zeros.
