Should one even care about the FL graph on ASV machine?

RE: Should one even care about the FL graph on ASV machine?
The Flow limitation chart to me, outside of the forced/timed/backup breathing is an indication that flow limitations are occurring and to look deeper while initiating treatment (typically higher pressure support). The detailed view typically shows far more flow limitation than the FL chart. Never chase the flow limits themselves if they are not causing an issue. So what SleepRider said.

I already maxed out my min PS at 6 so I guess there is nothing I can do regarding that part. I really wish Resmed did not put a limitation to pressure support min on such an expensive device.

Can you elaborate on what the detailed view is? Also I already maxed out the PS min at 6 so not much I can do regarding that.

View the Flow rate, 3 minutes at a time. This is detailed enough to show the waveform for manual interpretation.

Sorry there Michaely6. Something not right on the PC and OSCAR screenshot postings. I'm getting a nice blank white screen. After I consider what part to sledgehammer, I might be successful in posting info. I'm on a bronchitis required break for a bit...
BTW my FL was flat zero

This is one of the very best things about the ASV. The ASV is far from perfect and is not for everyone but this is for one really awesome aspect of the ASV. See to me the increased chaos on the flow limit chart is a direct ongoing reminder of how much higher starting EPAP & ongoing EPAP pressure the user would have to suffer through when using most of the other CPAP and BiPAP machines out there. Kind of like that line at the bottom of the grocery store receipt that says "This is how much money your discounts saved you today $xxx.xx" Written mostly based in facts and seasoned with a bit of 'tongue in cheek' WillSleep INFORMATION ON APNEA BOARD FORUMS OR ON APNEABOARD.COM SHOULD NOT BE CONSIDERED AS MEDICAL ADVICE.

Hi Michael,
To answer your original question. "Should one even care about the FL graph on ASV machine?" I think that depends on the User and how much help they need trying to sort out what is going on at a detail level through the nights. So people just get great results and don't have a lot of funny events that they need to spend time sorting out. Others find the Flow Limit chart valuable.

The detailed view typically shows far more flow limitation than the FL chart. Never chase the flow limits themselves if they are not causing an issue. First, I really like how Bonjour put it here. I will add that I use the FL chart in these ways:
////////////////////// I have not seen the chart your speaking of. I will just add that on an ASV the more spastic the FL chart looks the more likely Min EPAP would need to raise some in concert with Min or Max PS going up higher to address to beat the flow limits down to more reasonable number. Update: I will add that at least some of the flow limits and even sometimes even some hyponeas you can completely ignore. If the ECG device like a Dreem 2 or the 5 second updates to your HR and your SpO2 from your Pulse-Ox showed zero change, zero variation then what is reported in OSCAR may not have happened or if the event did happen it was a complete 'non-event' and did not disrupt your sleep in any way.
