@sueinmn A good tip that I heard while watching one of the videos Sue posted is the importance of the breath hold before huff cough.

The respirologist was explaining the different airway techniques and emphasized the importance of holding your breath between the inhale and huff cough.

I had thought that holding one’s breath for 4 or 5 seconds is standard, but he suggested that if we can hold our breath to a count of 10 or so, it can help produce more sputum when we huff cough afterwards. I’ve noticed the difference. I use postural drainage and a few breathing exercises and the longer breath hold does work over a session. I vary it up.

I wonder if people who have trouble with expelling sputum might just benefit from the longer breath hold too? The video was well worth the time to view it.
