It is normal to have air venting out of your mask. That flow is controlled by the size of the vent holes and the machine does not count that as leakage. Your leakage looks acceptable, but there certainly is some that changes through the night.

On the Aug 7 there are some obstructive events to look at.

00:14 - You have to line the cursor up carefully on your screen to be right on the event. In the top left of the Pressure graph it should show the pressure at that time (Pressure Set). It looks to me that the pressure was already at 10 cm, but that is where you have to look carefully and expand the screen some if necessary. Sometimes the event causes the pressure to increase, so you have to see what happened first. The event or the pressure increase. By my eye using your screen shot it looks to me that the pressure was already up to 10 cm. So unless you set the minimum pressure above 10 that type of event is likely to happen again.

02:21, 02:28 - Both of these obstructive events occurred at your minimum of 9 cm pressure. A higher minimum pressure may have avoided these events.

04:20 - 05:20 - There is a series of obstructive events in kind of a cluster and from my eye again I think these were all at your max pressure of 11.5 cm. These are the kind of events that could be positional and possibly avoided with a cervical collar. Or it just may need a higher maximum pressure.

On August 8:

01:35 - Obstructive event which looks like is at the maximum pressure of 11.5 cm.

04:08 - Obstructive event at 9 cm minimum

05:15 - Another OA at minimum pressure

05:40 - OA event at maximum pressure of 11.5

Taken together these events suggest you may benefit from both a higher minimum and a higher maximum. I always like to increase the minimum pressure first. My thoughts would be to try a minimum pressure increase in 0.5 cm steps. If you are still having too many events at the higher pressure then I would increase the maximum pressure as a later phase. Keep in mind there is nothing wrong with having the minimum and maximum close together. If you end up with a minimum of 11.5 and a maximum of 12 cm, there is nothing wrong with that.

Hope that helps some,
