The med is Trelegy; the vent is Trilogy. How long you use it is something you and your pulmonologist ought to talk about. Some people use it during the day as well as at night.

Trilogy that I use is an inhaler! Dont understand the question?

Four hours every night with a triology machine, that's the least

Doctor told Me to use 4 to 6 hrs.--I use at Night. Been on it for 4 years, gives me relief. Sometimes it is very annoying & I may take it off sooner & just use my oxygen.

I use mine at night. The triology machine they took me off. Trilogy. I think it was because of my insurance. I'm on medicaid. I won't have medicare until sixty five, which is in about five more months
