\ How much are you doing the recovery breathing?
M_arch, I wonder if it would be helpful to do capnometer readings an hour or two later and if the results of a Buteyko exercise would register then? Or maybe it would be good to take a capnometer reading at the end of each day, and see if a day that you did a lot of Buteyko exercises made a difference? Or maybe if a lot of physical exercise made a difference? (Enjoyable physical exercise makes me feel really good. So I suspect that it's doing good things for my CO2 levels, even though I have no way of measuring that.)
Artour then says, "The situation with the application of breathing devices (such as the Frolov breathing or the DIY breathing device) is different since the practicing person has to have large diaphragmatic inhalations and exhalations, while the capnometer can be used to measure CO2 inside the breathing device or near the place where air leaves the device. In this application (e.g., for the Frolov breathing device therapy), the results will show real CO2 values in the container at the end of exhalations and etCO2 monitoring and capnography waveforms can be used as biofeedback." M_arch, I think that this is really interesting, that Artour highly recommends the capnometer as a biofeedback device for the breathslim or frolov device. If you do any experimentation with this, I will be very interested to hear about your readings and results.
I think that the oximeter/capnometer and the control pause are measuring different things. I think that the CP measures respiratory strength. Athletes will automatically have a high CP.
I do recovery breathing whenever I remember. I haven't been focused on it, more just using it to see what happens to my co2 and o2 readings.
That's an interesting way to look at it! Although I have been into sports a lot of my life (and have a low heart rate to prove it), and I would consider myself to have decent respiratory health. My girlfriend who has suffered from asthma has the same CP as me (around 10 seconds). Mine is only slightly better, around 12 or 15 seconds at best.
Although I may have 'cheated' and been a chest breather most of my life, when I first read about buteyko I noticed I mouth breathed at night which is a big no-no.
I have a frolov device but don't often use it. I find it very difficult and uncomfortable to breathe from to be honest - perhaps this is due to chest breathing?
Interestingly I can exercise relatively easily while nose breathing (but i'm guessing you can still chest breathe while nose breathing?). Maybe you know something about this?
The frolov device does sound interesting, I think I will try it out some more.
