Is it possible for a ResMed S9 Autoset to "interpret" blockages in the nose caused by congestion as obstructive events?
I am more "bunged up" than usual as winter sets in and the heat comes on, and my AHI have moved from below 1 to around 2. Cause for concern?

Re: Congestion as obstructive apneas
I would think the answer is yes. If you have a blockage, I don't think the machine can distinguish one blockage from another.
For instance, if a person holds his/her breath until they pass out, the machine has no way of determining if the airway has involuntarily closed or if the person is just stupid.

Re: Congestion as obstructive apneas
It may be that the machine sees the congestion more as an hypopnea than an obstructive event. It might also see it as a flow limitation which wouldn't be counted in the AHI..

Re: Congestion as obstructive apneas
IMNSHO, your flow limitations are a bigger problem. Do you feel rested after night's sleep?
