He does clear tremendous amounts of sputum daily. His most recent CT indicated a significant reduction in the fluid in his lungs from the previous scan taken six months prior, which was done before the MAC diagnosis and corresponding treatment/therapies began. He has another CT scheduled for early June, following a much longer period of treatment, which may show a greater amount of fluid reduction. Fingers crossed.
I agree that we need to discuss vest usage further. The potential downside of the impact on his already fragile physical state has to be considered if using the vest is to be an effective component of his treatment plan.
