The default values have been edited on the patient's profile. Things of note for a newbie:
* ''The CPAP information'' on the left side of the panel is largely irrelevant at this point. SleepyHead defaults to a statistical model for approximating the (excess) leak for all machines other than the ResMed S9, which records only the excess leak. If you forget to change the Leak Calcs from "Mask Profile" to "Statistical Model" it really doesn't matter.* ''===CPAP clock drift'' === should be left at 0 hours, minutes and seconds unless you know your CPAP clock is off and you can't change the CPAP's internal clock. This patient's With Resmed models you can set the clock in CPAP settings. Philips Respironics owners cannot access the clock , and may need to offset time drift. The best way to do this is off by a whopping 23 minutesto record your start-time, and because it's a Philips Respironics System One-- she can't change reset the clock drift the next day using the CPAP's clock; hence Clock Drift. Time offsets may be positive (advance time), or negative (move time back). For example, if your start time is 10:00 PM and the offset Sleepyhead charts show a starting time of 1380 seconds08:15, you need to move the time ahead +01:45. If the starting time on the charts shows 00:10:00, the time would be moved back -01:50:00.* ''===Show Leak Redline.'' === The default is to have this checked and the default value for the Redline is the ResMed value of 24 L/min. This is a NEW feature in SleepyHead 0.9.6. If you are using a ResMed S9or S10, it's strongly recommended that you make sure Show Leak Redline is checked. If you are using a different machine, this may be a useful option for you, but you will need to change the value for the Redlineto reflect. More on that later.See [[A detailed look at the Show Leak Redline option]]* ''Show compliance'' affects how low usage days show up in the Overview data and the compliance data in the Statistics page. The default line is 4 hours for obvious reasons. It's suggested that you leave this alone. Most insurance defines "Compliance" as greater than 4-hours of therapy in any 24-hour period, for 70% of any month (21 of 30 days).* ''Custom User Event Flagging.'' It's recommended that new CPAP most users leave this unchecked. It can be useful if you have a lot of "almost" apneas or "almost" hypopneas showing up in your detailed data, but it really is an advanced feature.
* ''AHI/Hour Graph Settings.'' The default is to have the box by Zero Reset unchecked. Leaving the box unchecked tells the AHI/hour graph to keep a running total of the number of events (OAs + CAs + Hs) that have happened in the last 60 minutes. To make the AHI/hour graph behave like the ResScan AHI/Hour graph, you need to check the Zero Reset box; then the AHI count is set back to 0 at the top of every hour.
