VPAP ADAPT SV data

[cicero28374]

My data is fairly static, but some worries me.
leak is 0
AI is4.8 monthly and 4-6 daily means what?
AI is 0.1
Pressure is 9.4
VT is daily 246-668 and monthly 204-718, range seems very large means what
resp rate 13-21
MV is 4-10 means what
Where there is only one figure that is daily, weekly and monthly.
And insight would be appreciated. New at this.
God have mercy on us all

Don't do as I do, do as I say: Read your Manual for the adapt and for the software.

Assuming you are using ResScan 3.4, run a report, check the last page, it is an explanation of what "they" all are.

MV=Minute Ventilation=the volume of air breathed in or out w/in any 60 second period
TV=Tidal Volume=the volume of air inspired or expired w/in one respiratory cycle (breath)
RR=Respiratory Rate=frequency of breathing, expressed as the number of breaths per minute
AI Day=number of apneas per hour that night
AI Month=average number of apneas per hour for the most recent month
AHI=number of apneas AND hypopneas per hour for that night, average number for the most recent month, etc.
Pressure=the pressure AT OR BELOW which you spent 95% of the night

I have the Resmed VPAP Auto so am not sure of just what all the Adapt SV "reports".

Don't have any software, this is from the screen. The first AI should be AHI.
Do you have any idea where I can find normal values for these data. not RR, Pressure, and leak, but especially for VT, that seems a large variation.

Hi Cicero,

Just some quick thoughts on your data.

1) The AI numbers are fine.
2) The HI numbers are higher than you might want them

The real helpful data is what can be extracted from the machine. To do that you need Resscan 3.5 software and a null modem cabel ($15-$20 from Radio Shack). Don't worry about a card reader as there isn't an inexpensive solution (you have to buy a Reslink module and the cheapest Slinky & I have managed was approx $190). Your PC will need a serial port to connect the machine to your PC via the null modem cable. The type you need has DB9 connectors at both ends rather than any DB25 connectors.

If you are able to extract a nights data I can give my evaluation of it.

We may be able to fix the high HI numbers but that may require cautious adjustment of the PS settings (pressure support). Your MinPS appears to be fine. I'd need to see more data before suggesting which settings get adjusted if at all. I am assuming you have the leaks well under control but again need to see a few nights data to be sure.

Cheers

Frannkly, the numbers really don't tell you as much as looking at the data and determine justt how much variation one sees in the MV data. If it is a nice tight plot, vertically than the machine is doing good things for you. Assist SV data really isn't a read by the numbers like all the BiPAPs and CPAPs.

watch out for excessive leaks - too much mask leak isn't effective for the algorithm
