Either I am not very observant or Variable Breathing Event is new to my OSCAR data. I could not find a definition of this event anywhere. What is VBE measuring?

UNCONFIRMED: Possibly variable breathing, which are periods of high deviation from the peak inspiratory flow trend.

That's the description in the Events tab under File...Preferences. I'm not sure what "trend" means here, but I interpret this as meaning a period when your inhalations are shallower. As I'm imagining it, this would show up in a zoomed view of the flow rate graph as a stretch of curves about the zero line that don't reach a peak as high as your usual peak.

I can't doublecheck that, because Oscar doesn't do this trick with my machine's data.

I looked everywhere but the most obvious place. The vertical green lines represent a pattern I saw in the wavelengths. The solid red line is the time the VBE was reported. Does it also appear that the peaks are flatter indicating a pause in breathing?

"Variable breathing" is a pattern of waxing and waning of the breathing flow volume, in extremes, it will go to Cheyne Stokes Respiration, where your breathing fades completely out to nothing, and fades back in over a period of time.

There is no evidence of that in the clips you provided.

Typically, if you are going to show an event and ask a question, put that event on the right end of the chart, because whatever caused the event is to the left of where the event is flagged.

What you're showing is an irregular breathing rate.

Thanks for the advice. Here is all 224 minutes of the VBE @23:45:30 reported in my original post. I see a slight reduction in amplitude but not a whole lot of difference after 23:45:30. I have a lot of these throughout the night but most are 1-3 minutes in duration.

There is some variability in the amplitude of the breathing, if you look at your tidal volume, it should be going up and down, but there's nothing in that to worry about, I've seen far worse... like going completely go zero, repeatedly.

I get this, variable breathing, a lot. In my case I assumed it was due to the fact that "I" have constant Atrial Fibrillation AND Arrhythmia (arrhythmia is a problem with the rate or rhythm of the heartbeat). Looking at Whiskey-Romeo's posted waveform you'll notice that the time interval between the "green vertical lines" is variable just like what occurs for arrhythmia. During an arrhythmia, the heart can beat too fast, too slowly, or with an irregular rhythm. When a heart beats too fast, the condition is called tachycardia (which I occasionally had before being medicated). When a heart beats too slowly, the condition is called bradycardia.

Hi Jas,

I 'had' AFIB, but, at the time of this post, I was two years after a laser-ablation. Haven't been in AFIB since. I posted links to topics that provide a great explanation (it is not limited to people with heart problems). I am not sure I posted these URL's correctly but at least you see the topic number. Maybe on of the admins can fix them or help you get to them. They offer a lot of good information.
