Using the design of a prospective randomized control trial (RCT), patients will be randomly assigned to either of two groups: (A) humidity therapy with aerosol using a large volume nebulizer, or (B) humidity therapy with molecular water vapor using heated humidity. A sample size greater than 100 participants will be the target, as the proposed study intends to address the small sample size limitations of previous studies. Furthermore, the study period of approximately 60 days is desired to observe the long-term outcomes that may result.
