Multiple huff coughs for me. From nebulizer --> completion of "breathing exercises" is approx an hour. Since the disease (bronchiectasis) is heterogeneous, each has a different experience. Add infectious processes on top and differences are compounded. There is no magic number of huffs etc. Trial and error is the best teacher I've come to realize.

If you're having trouble bringing up anything, Dr. McShane (Tyler, TX) recommends nebulizing 2 x 4ml vials back to back. Find out where your bronchiectasis is in your lungs so that you can target those areas with postural drainage. Try everything - lie down on your back, each side, upright, slanted back, etc. Give it time. AD app is a good place to start in all those positions. I hope this helps somewhat!
