spirometry tube and hoffing

I use the plastic whiteish clear ones that come with disposable nebulizers. Sometimes I cut them in half so I have more. They seem to disappear easily. And sometimes I temporarily stop using because it's tempting to exhale too hard through the tube. I vacillate but they are good to have around to help keep glottis open during exhalation.

Ah, many thanks Scoop. That is smart. I will check. I think hoffing correctly is so crucial for a good airway clearance. The tube will make sure I am doing it right. Once I have muscle memory, I may not need it any more. But like you said it is a good idea to keep them around.
Thanks again.

In case it helps, the autogenic drainage video demonstrates how the tube in mouth is used to help keep glottis open. Such a great site filled with valuable info.

Many thanks again Scoop. What a great site.
Have you tried to use an Aerobika mouthpiece as spirometry tubing for huffing? To use the round end, that will make the mouse right shape I wonder if it works efficiently as a spirometry tubing.

Yes, I've used the aerobika mouthpiece in the past and it works just fine but I prefer the tube as it's a slightly larger diameter.

Speaking of aerobika, since I've stopped using aerobika concurrently during saline I find that I am not missing it. Autogenic drainage app for me is more effective without aerobika. Of course will keep for now but I am happy having one less thing to sterilize.

If you are active and exercising, I guess maybe aerobika is not a must? I am very active, after exercises like walking, hiking, stepping up the plyo box, yoga, taichi ... I normally don't have mucus coming up. But I found Aerobika with breath holding for 3 seconds is quite effective for me. A lot of time, mucus jumps to the throat while doing it. I do want to shorten the time of doing it to experiment.
As for the Autogenic drainage app, do you use the one with 2.5, 4.5 and 6 minutes length? I do find it very effective, that is the one I like to use after aerobika. What do you use to cut the tube? I purchased it.

Most often I use 2.5 minute option sitting upright. When the stuff thins out I change to my back and then sides. I also use active cycle of breathing before huffing. Regular scissors to cut tubes in half.

I think you are doing everything right, which keeps you safe from MAC. I don't know if I have MAC or not, I think the bronchoscopy probably will tell. I am going to do it at the end of July. My 3 sputum test results were all negative. But I have big nodules, they don't shrink. I hope the bronchoscopy will find out what causes the nodules.
Keep up the good work and take care!
