@cayenne thank you for responding, I do understand the time difference is amazing. But the worst of my BE is in both lower lobes and towards the back (posterior) therefore that where some of the mucus is that’s Soooo hard to get moving. Do you have the worst of the BE in your lower lobes? I’ve been told that the deeper the BE is in your lungs the harder to expel and therefore harder to get saline to to help thin. Can you tell me where your BE is located in your lungs?
