Need info on UF 1 and UF2 on SH

[SideSleeper]

Read advice on the Main forum about adding UF1 and UH2 to Sleephead--topic was about RERAs. How is this done and what do these figures mean? Thanks in advance.

Hi SideSleeper. To access the user events in SH, go to File | Preferences | CPAP | Custom User Flagging Event.

You can set two types of events (UF1 and UF2), defining them by flow restriction and event duration. Maybe you are concerned that you're getting short-duration apneas that aren't flagged by the machine - set a flag for 80% restriction and 7 or 8 seconds. If you're concerned that the machine is missing some hypopneas, set a flag for 40% reduction and 10 seconds. I'm not really sure what you'd set to catch RERAs but perhaps something like my hypopnea setting (but with a shorter time scale) would do the trick.

I appreciate the information!
