When I have to get up in the night I press the machine stop/start button and disconnect the tubing at the mask, the machine then blows out a 5-10sec blast of air and switches off. I think this is the recommended procedure and so far so good. When I return I push the button (ON) again and it lights up and says "Treatment". Two things happen first it appears to go back to Ramp mode (expected?) and second it fills my mask with air but does nor respond to my breathing in/out cycle at all. It feels like a lowish pressure of air is being constantly delivered to the mask in a continuous flow.
I have two questions, first I think I know the answer to anyway. If I want to avoid the machine going back to Ramp when I return to bed I am thinking I should just disconnect the tube (and not switch off).
The more important question is why is my machine not restarting with its usual breath in/out air delivery mode?
Welcome to the forum.
Based on you description it sounds like you have the S9 in the Autostart mode. The S9's manual states that the Autostart feature won't work (at least for starting it) with a full face mask. If you wish to use this option you will need to switch a nasal or pillows type of mask. The S9 will have a slight start ramp regardless of the Ramp option being on or off. The start ramp was designed to ease the patient up to their initial pressure so it won't be such a shock to the person's system. If you have the Ramp feature turned on, the S9 will always employ it whenever you start the machine. If you want to start the S9 without the Ramp, you will have to disable it prior to starting normal operation.
The S9 has a peculiar behavior that requires the the unit to be totally powered down (power cord removed) for a few minutes in order for certain features to be reset after a change. It is a hit and miss as to which feature. My advice is to power down after making any operational change. They seem to be center around things like Auto/Manual changes.
