pressure plateau

[SarcasticDave94]

Not answering for others, but 2 minutes seems to give breath by breath data on flow chart and can show details that those with experience can see issues by looking at it at that level of zoom in relation to events flags, etc.

Dave is right. With this resolution we can really read the tea leaves. For example see that weird flat spot at 12:44:55?  That is probably a swallow durig expiration with a brief exhale of air before the next inspiration.  All of the inspiration waves here show a very crisp, strong inspiratory effort and free-flow. Not a flow limit anywhere.  The CA event appears to be a pause in exhale and is atypical for a true central because respiration before and after the event are about the same with no diminishing volume before or recovery breathing after.  You can see a pressure pulse indicated by the black hash next to the CA event and you can see the deflection it caused in the flow rate. This is how Philips differentiates obstruction or clear airway. I would guess this event is a position shift.  The hypopnea is just a diminished effort, and has no indication of flow restriction, although the last breath of the hypopnea looks a bit flow-limited.  You see those little waves where there is no flow during the CA and H events?  That is your pulse which the heart atrium transmits to the lungs, especially when laying on your back or right side.  That s what a 2-minute segment does.

Make your chart even better. Right click next to the Flow Rate label and a menu comes up where you can reset the y-axis range and add a dotted line. Try adding a dotted line at zero. That will show you where respiration crosses over from inspirations to expiration and back.

right click/dotted lines/zero
You can set right click/yaxis/overide/ +/-75 and that will encompass all you need to see except perhaps in a few unusual situations.

you meant 11:45:20-30, I do, yeah. A true CA.... ok.

Plenty of them last night yeah..... chin strap kept messin with me as well as the P30i head hear. Pillow was messin with me, and my shoulder was sore from laying on it a long time.

Right click next to the Flow Rate label, then click 'Dotted Lines', then click 'zero'

Got it.... I think we should change Freds user name to Ghost ! LOL Thank You Fred !

Yeah This board definately is theee Best !

So in the 2 minute segment, a legitimate CA is 10 seconds.... it's hard to see the time of 10 seconds but I guess I can manage.

Not really. The last one is has a large breath right before it that could be a yawn or just a sigh. Once again the following CA was just things coming back into equilibrium as you didn't need the air. It's a sleep or breathing disturbance frequently flagged as CA because the airway is open, but is not a neurological or similar cessation of breathing.

Back near the beginning of this thread you had some impressive repeated clusters of CA that might have been a real concern if they continued, but these breathing anomalies are pretty common. Nice job on the dotted line. Similar context menus are available on all the charts...explore.

I just posted a screenshot with a posted green line with the time line..... next to the purple CA flag. Trying to time it, but the time line is a bit to read. I only had one OA.... I should keep the pressure where it is.

Will do. copy and pasting into the quote box takes awhile. i used to color code my answers in reply in prior post quote.

Now that I can read the flow chart correctly, do you fellas think i still need to have titration study?
