Hi again, - it's good to see you remaining engaged with the community. I recall we had a conversation or two, a few months ago and it's nice to speak with you once again.
There is not much in the way of objective reviews of this type of oxygen delivery device, marketed as either the 'Uni-flow2' or 'Oxy-Breather' single oxygen cannula. I was able to find one brief comment in a 'sleep review' magazine, which simply describes it: https://sleepreviewmag.com/sleep-diagnostics/in-lab-tests/polysomnography/uni-flo2-single-nasal-cannula/.
I believe there isn't much in the way of literature since its indication for use and, even its success, can vary widely from patient to patient. Depending on your own particular and specific set of needs, you may want to try it out. You also may want to discuss it further with your physician or even, a salesman for the manufacturer. What do you think?
I am also hopeful my clinically-based colleagues, ( and ), will weigh in with their own experience and input.
All the best,
