Hi Folks!
I just moved from an Aircurve 10 BiPAP to an Aircurve 11 ASV to control CA events. The 11 ASV has gotten my AHI down, but when I'm looking in Oscar (v1.6.0) I don't see any information about CA events from the new machine!
I looked through the Aircurve 11 ASV manual and it still says CA events are logged to the SD card.
Does the Aircurve 11 ASV actually log those events to SD Card?
Does Oscar not support that data import yet?
OR
Have I bungled something in my configuration?
The Resmed Aircurve 11 ASV will mark any apnea as "UA" or unknown because there is no Forced Oscillation Technique (FOT) used to determine the apnea type. In nearly every case, an apnea flagged as UA will be obstructive. With an open airway the adaptive pressure support is normally sufficient to cause airflow or a normal breath. An obstructed airway will not allow air to pass, or may resist airflow resulting in a hypopnea. There are exceptions. If you want to breakdown your chart data, feel free to post a daily details chart and we an see how events arise and then zoom in to see whether they are likely obstructive or central.

I'm still adjusting to the ASV, I've only used it for about 5 days now. The reported AHI is great compared to where I was on the Bipap!
I just reread the manual and noticed that during my first and second read I read AirCurve 11 ASVAuto... but it just says VAuto. I must have ASV on the brain.
Once I have a few more days under my belt I'll fire up a new post in the Main Apnea Board Forum (I think that's the right place, I'm a newbie) asking for help.
The Vauto is a spontaneously triggered bilevel used for obstructive sleep apnea, while the ASV is an adaptive servo ventilator that can trigger breaths and adjust respiratory volume for central and complex apnea. Can you clarify which you have or post a chart?

I am currently using the AirCurve 11 ASV. Previously, I was using an AirCurve 10 BiPAP, but I experienced continuous CA events. After discussing it with my doctor, we decided that I should switch to the ASV, which I am now using.
I found a sticky post advising me to reset my chart display to standard and post a screenshot, so hopefully, you have the charts you were looking for.
I can tell your leaks are too high to ignore. It needs fixed ASAP.
The chart is almost right. We also need the left panel intact for context.
I would swap Pressure for Mask Pressure. Drop the Flow Limits chart down, they'll look much like this on ASV no matter what, unless I use ASV. My FL was uncommonly clean.
OSCAR: Events, Flow Rate, Mask Pressure, Leaks are probably good enough. If others require something else more needful, they'll correct me.

SarcasticDave94 - Agreed, this was a terrible night. There are times that my wife has mentioned that my mouth is open. I’ve tried chin straps of various types and find them supremely uncomfortable. I have facial hair, and mouth tape is rough and not something I’m into. I have not tried a cervical collar though! Most nights I have one burst of leakiness for a short period and it goes away. I need to gather more data while on the ASV, it hasn’t been that long.
Crimson Nape - Thank you!
Sleeprider: My apnea has a positional component. I should always sleep on my sides, but I find it difficult. I tried a nightbalance but it wasn’t very effective (for me!). The cervical collar is interesting… I need to give it a shot.
The ASV is working reasonably well as is, my apneas are (so far) consistently better than 3.5, which is huge. With a little more tuning, I’m hoping to get that down, but I’m letting myself acclimate to the device, which is a big change from the bipap!
