Airsense 11 problem inhaling

[Fred567]

I have been using an Airsense 10 with a few different masks but most recently Vitera. I had no problems inhaling. A couple weeks ago ( Oct 6th) I switched to an Airsense 11 and the 1st few days I had the F20 airfit but changed to f20 airtouch which I like much better than any other mask I have used. The only problem I have with the new system is I often struggle to inhale, especially when I 1st put the mask on, return from the bathroom or wake up. I am really sucking hard and can even hear a difference in the hose noise which I dont usually hear at all. i have to force myself to leave the mask on as I know there is/SHOULD be plenty of air and if I lift the edge it does come gushing out. Do I have this issue while sleeping? I dont know. I have compared the settings on both machines a few times and they are the same.
Any ideas?  could it be the mask? ( I hope not I really like it)
My sleep with the new setup is much better than the old. I have attached a couple charts but I dont know how to read them.. Again, Oct 6th I started with the new system

Turn smart start OFF and use your button on top of the machine. That will solve your problem. If not turn on the machine and wait 1 or 2 seconds and put on your mask.

The flow limits are really showing in your data and they occur periodically through the night. I'd like you to increase minimum pressure by 1-cm and increase EPR to 3. I would suspect some positional component to these clusters of high flow limitation, but you describe sucking air, and so it's unlikely you are chin-tucking. I think the increase in pressure may help you with air delivery and EPR should further improve ventilation. The change makes your minimum pressure 11/8 rather than 10/8 (inhale/exhale) and maximum pressure is 18/15, but based on this you won't reach that. We'll see what that looks and feels like, then if we still see these flow limit episodes with the fluctuating resp rate and tidal volume happening, we can take a closer look.

Thank you for the explaination and info. I am a side and belly sleeper and constantly roll side to side and dont think I do chin tucking but maybe I do. I have changed the setting as you suggested. Hopefully it will help.
