Speaking of playing the bongos, here's a great tune to get a Rhythm. The heart and lungs operate from a rhythm too.
As a youngster, I remember sitting close to the HIFi speaker while listening to music. Somehow, we did fell better when we took a deep breath and then ran off to play.

Hi Phillip. Few have mentioned the Vest use in this Forum. But another method may be just as effective and at a reduced cost. You just need two extra hands.
Anyone can be trained to perform the chest percussions described in this video. There are other videos showing the technique in more detail. If you know someone who can keep a good musical beat, that's even better. 🥁🥁
Be well.

Haven't tried it; I don't need to use one. Many people who have bronchiectasis or similar diagnoses who need to cough up a lot of junk every day swear by them.
