Hi JJordan. Given you had 4 clear airway events, 2 hypopneas and 46 obstructives, that's a total of 52 events in total. If your AHI was six, this implies you slept 52 / 6 = 8.66 hours. Is that about right? The target is an AHI under 5, and generally as low as possible. For an 8 hour sleep that will still give you up to 40 events, so you're not too far off the target. However that's still quite a few events for the night and it's better to get the number down.
The machine senses when you stop breathing and after a few seconds starts a rapid small pressure fluctuation to determine if you have an obstructive or central (clear airway) event. You can see that as the zigzag in the mask pressure line towards the end of the apnea event on your screen dump. It then increases pressure as required, which is why you are unlikely to see an apnea longer than 20 seconds while under therapy.
I see you're using an Autoset, and your pressure is stated as 10.9 auto. Was this the maximum pressure reached? If you can upload the screen dump with the details shown (the pie chart and the table of numbers under that) we can be more specific. However on the face of it (and with the usual disclaimers) I think you could benefit by increasing both you maximum and minimum pressure a bit. This should splint your airway better and make you less prone to obstructive apneas.
