OSCAR is not all that hard to understand. It reveals the detail behind the numbers. See this example of the important graphs that it produces. You can see when the various types of events occurred. For example at 3:10 there is a CA. central apnea event, flagged with magenta. It happened with pressure about 14.5 cm. Note that the cpap does not increase pressure in response to a CA. A little later at 4:30 or so there is an obstructive apnea event, blue, that does result in an increase in pressure. Pressure was very low, too low, and that likely caused the event. There is a rapid response with an increase in pressure, but it is too late. Pressure at that time was set at a minimum of 6 cm and 20 max, which was where the sleep clinic set it. The minimum pressure for her was way too low, and the maximum was too high. A bit later she has another couple of events around 5:40 when the machine has ramped the pressure back down again. She currently uses a min and max pressure very close together in the 14.5 cm range to avoid this from happening. She was diagnosed at about 73 for AHI, and needs a much higher pressure than you will. In any case that is what you can do with OSCAR. It is essential in my opinion if you want to adjust your own pressures. Otherwise you are just shooting in the dark. You can post your results here for input if you are not understanding what they are showing. No need for all the reports that OSCAR can do. The main one is this Daily report. It has the important stuff. With a PC use F12 to capture the screenshot. Then just drag it with File Explorer to an open message here. Start with a fresh full width window, not like this one will be with a response to another post.
