I'm new to OSCAR and chart reading.
My AHI was diagnosed by my Pneumologist at 11. She said it consists mostly of flow restrictions.
I've been using a ResMed AirSense 11 AutoSet with a Simplus F&P (full face) mask for a week now.
Right now we are trying a low pressure (4 cmH20) because I have aerophagia when using the machine. At 4cm I can tolerate 8 hours of CPAP but not at 9 cm.
According to OSCAR and the ResMed data, last night my AHI was 3.77.
However when I add in Custom Event Flagging based on Flow Restrictions > 50%, I can see that I have as many UFs as CA.
Since UFs are not included in the AHI, the AHI only gives a partial view of the situation.
When I zoom in to see what is going on around the CA and UF events, most of the time I find that 20 seconds prior to the start of the Event there was an increase in the Flow Rate, the Tidal Volume and the Minute Vent.
I would have expected the Flow Rate to increase AFTER the event, not BEFORE, but as I said I'm new to this ;-)
What do you make of this ?
Thanks...
