Isn't this "I don’t feel like I am getting anywhere" a frustrating feeling?
For all of the activity you see here on the MAC & Bronchiectasis group, we do have a "rare" disease - or actually 2 of them.
If you are becoming light-headed while while nebulizing, you need coaching in proper breathing while doing it. The inclination is to "really suck in hard" to get the meds down into the lung, and many of us begin like that. But your breathing should be more normal, with pauses between inhale & exhale to let the aerosol do its work & penetrate into your lungs.
So...sometimes it is necessary to become out own best advocate in our care. It sounds like the RT you visited with may not have been the best one for you. Instead of a Zoom consult, it sounds like you need to push for a in person RT with someone familiar with bronchiectasis. There are many techniques you can learn to try to get the mucus moving...
Can you ask for in person therapy?
