Hi Pete,

Thanks for the link. I will review in detail when I have more time. It is my understanding that this value only can be used with whatever that gadget is called that goes down inside the trach. I do not need or use one of those.

Can the passy-muir also be used with an adhesive collar? I've heard of the passy-muir from nurses that took care of me when I had the carotid done. There were very curious about what I was wearing and seemed to feel that it was superior to the passy-muir, although I have no idea why.

I have 3 hands free valves, 2 from InHealth and one from Atos that fit into an adhesive collar that I glue on each morning. I don't use them because I blow the seal on the collar too frequently. I use the Atos HIFlow value because it gives me the best breathing. If you don't know what my gear looks like, I will try to find links for you.

Take care,
Eileen
