Kathy-
The postural drainage is for all lobes.
One of the positions that I do: I reverse the wedge pillow and place my hips (posterior side) up on the high end of the wedge and lay back to have gravity and percussion clapping help move the mucus. While doing that I sometimes gargle some mucus up and have to interrupt the position and go back into it again.
Yes inhaling through the nose, holding the breath and releasing with pursed lip is what I try to remember to do often.
Good information shared thanks...I appreciate all information and make my decisions on what I hear/read according to what I feel is safe, comfortable and not "crazy". My Mom introduced us, me/siblings, to complimentary/alternative medicine. She was into it way back in the 1940's.
Kathy- My breathing is fine. The lung function test is off the scale in the right direction for me. You appear to be working hard at finding your way...me to...It takes time and then it appears it all will come to be second nature and go quicker...the time devoted to our lung problem routines.
Wishing you a great day and lots of good breaths.!
Barbara
