It's good to know how to use it correctly. Thanks for sharing

Good video. Lots of good information.

Excellent job tans 🎉 Very helpful video.

Please I had a locbectomy but my spirometer is a simple cylindrical container with a single ball. I am finding it difficult to keep the ball suspended. The ball moves so fast and I am not getting the impact. What do I do?

Thanks for the video

Thanks 🤝

What would your goal be if you are 67 and 5 foot tall?

Thanks, this is awesome and really helpful! I have a couple questions: I was a bit confused by the recommended interval, did you say that it's generally once every hour with a single set of 10 reps? Would you recommend this device if I'm just trying to increase my lung capacity for exercise in general (swimming)?

Hi Doc, thanks a lot. I have a pulmonary densities in my both lungs, due to metastatic breast cancer. Can I use Spirometer?

Can we do expiration with this?

Hi Doc. I hate to bother you, but I can't find the Voldyne 5000 Incentive Spirometer anywhere. I did find the Voldyne 4000 and the Voldyne 2500. They look the same or similar but, of course, one goes to 4000 and the other to 2500. I'm a 5-foot 3-inch-tall woman (68 y/o). Would the 2500 or the 4000 be ok for me or do I need to keep looking for the 5000? OR is there another brand that looks and functions the same?

Whats a good goal to reach?
