Hi Sheryl, sounds like Charles is doing well.
I'm not sure about the smell.,I don't remember Kris having a smell coming from the Stoma. I presume that he is nebulising saline via the Stoma. This helps to keep the mucous liquid and more easily coughed out. Kris still nebulises every morning.
Did you manage to sort out a means of communication for Charles?
Hope you have him home soon.
Tammy
