Also going to add the ones I bought on amazon that didn’t work were much thicker than the contec ones, the connector did work though, but I think the thickness of the space in the tubing may need to be the same perhaps to work, and the contec ones are very narrow. Thicker ones are probably for oxygen delivery and other uses and not co2 reading.
Hi, I wanted to give an update. Capnometry biofeedback worked better than I expected. My baseline ET CO2 went from around 27mmHg to around 40mmHg in the first 1.5 weeks of using the device, and stayed there for the whole month I had access to the device. (I’ve now returned the device.) The key thing I discovered was that even though I was already nasal breathing 99.9% of the time, my nasal breaths were still quite audible and so I was overbreathing because of that. The biofeedback+coaching allowed me to switch my breathing to a silent nasal one in stages. I still experience air hunger, but it is a lot more subtle than before. I still have trouble talking, some of the time (I think talking makes me overbreathe, so if I start out with no air hunger then I can talk for quite a while, but if I start talking when I already have some air hunger, then I quickly reach my limits). I still on occasion mysteriously have a lot more air hunger than normal and feel like I “forgot how to breathe”, and I wonder if that means I have some sort of autonomic problem… I’ve been writing up a lot of my thoughts here. I might retry capnometers in a few months or a year or something, but for now my plan is to go back to (original Russian-lineage) Buteyko method and really logging the time (rather than half-assing it, which is what I was doing previously with Buteyko). Feel free to ask any questions.
