Love this analogy. Thank you. This past month I had to stop big 3 due to lo platelets. So I am now religiously doing airway clearance daily. My routine is 13-15 min. 7% saline nebulizing. ( with intermittent cough clearance). Then aerobika about 20 breaths. Then blow my nose. Then 3 ( or more) slow rise and hold, yoga bridges. (Postural drainage) I intermittently huff cough with a cup by my side). This clears at least 1/4 cup of sputum daily. To finish, I drink 10 oz or more of water.
All these techniques were handed to me from this wonderful group. Thank you to everyone.
