I work in Scotland. Our unit actively looks for ibtermittent hypoxia on saturation studies predischarge and then treats with home oxygen. Almost all of our <28/40 go home on oxygen as a result although many of them would pass an air test and not have BPD. We are looking into prolonged treatment with caffeine instead to treat IH similar to the iCaf study. We as a group are open to embracing this but undecided about how long to treat for and how to stop. What are people doing?
