Help/advice with Astral 150

[costaricaraftguide]

Hello! I'm using an astral 150 for shallow breathing while I sleep. i weigh 72 kg so the machine is set to an Avg Vt tidal volume of 595 ml , MV 5.4 L/min and avg vt/kg 8.1 ml/kg. I just double checked those numbers. BUT on the Rescan compliance report for the past 30 days I see a 5% tidal volume of  924 ml    median  1170 ml and   95% of 1506. I feel if I really was receiving 924 ml of tidal I'd feel a strong pressure. It doesn't feel that strong. it feels like a normal cpap machine like I was using years ago. If I really am receiving a median tidal volume of 1170 I'd be at risk of blowing my lungs out..... thoughts?

I had the Astral 150 for about a month several years ago.  I remember my average Vt tidal volume was set at 400, 450, and then finally set at 500.  

I think something is off on your machine and/or software reporting.  I am 6'2.  Unless you an absolute giant, I think 1170 ml would be very difficult, if not impossible to sleep with IMO.  A 95% of 1560 ml is very massive also.  

I have a question for you also, costaricaraftguide.  The Astral turned out to be unusable for me due to setting off at least 7 different alarms with my breathing pattern at night.  Does your breathing set off any alarms on the Astral during sleep?  If so, which ones?  

Thank you very much and I wish you well.
