Okay, I tried the eflow this morning and was shocked at how quick it was. I think the pulmozyme was like 2 minutes or less and the colistin, normally 20 minutes, took about 6 minutes. I was amazed. Once I get the hang of cleaning the thing, and remember I can't put cold medication in the eflow things should go quicker. Today I was extra careful about cleaning and it took a while. I also couldn't believe how quite it was.
