@heathert. Hi Heather...thanks for planting the seed of deeper, bigger breaths while nebulizing. I started doing belly breathing and holding the saline in for a count of 8 or so. What an amazing difference in the junk that I am able to expel. Wow! It has been productive since I started this and I must say it is still at least 5-10 times more sputum than with regular breathing. I started slow with maybe 10 belly breaths and at first it was a little difficult to belly breathe and hold it but now...easy peasy and such clearance!! Thanks for your brilliant thought! I read you were having cardio issues...sorry! I hope you get them worked out and feel better in the new year!! xxoo Kate
