Sandman Auto IFL Enabled or disabled?

I have tried my Sandman Auto in both modes(with IFL enabled and disabled) and as I haven't figured out how to transport the reports I will share results.
On 12/26 it was disabled with settings 6-12, on 12/27, it was enabled with settings 7-12
12-26 12-27
Apneas 1 0
Apneas CA 0 0
Hypoapneas 3 6
HypoapneasCNT 9 19
Snorings 0 1
Runs 455 335

I was much more comfortable with it off and the pressure stayed 6-7 with 90% at 7
With the IFL enabled, the 90% was at 12 and the higher pressure woke me up several times plus it increased the leaks, which are a terrible problem for me. Are the HypoapneasCNT something I should be concerned about? What exactly are the Runs and what do they mean?

I know little or nothing about the Sandman Terry but I see that you changed your pressure range from 6-12 with IFL disabled on the 26th to 7-12 with IFL enabled on the 27th. You changed the pressure range AND the IFL.

Changing 2 things at the same time, and in just 2 nights, makes it hard to compare the results. You can't tell if the pressure change or the enabling/disabling of IFL made the difference, although it does look like (again I don't know this machine) that things MAY have been better with IFL disabled. You should leave the IFL disabled for 3 or 4 nights and leave your pressure range the same for 3 or 4 night as well (either 6-12 or 7-12). You'll have more consistent data and a longer term to compare that way.

Hypoapnea CNT and Runs I don't know about. I THINK that Hypoapnea CNT are central hypoapneas and, therefore, not as bad as central apneas. I think these 2 things are exclusive to PB machines.

Yes, Hawthorne, you are right, I probably shouldn't have changed 2 things at once. I wanted to try the lower pressures as I have a terrible problem trying to keep my masks from leaking. When I used the lower pressure, my blood pressure was high the next morning and I guess I am still a little anxious as when I used my Respironics I had terrible headaches and increasing blood pressure because of the co2. I think I am going to order a recording oximeter so will know if there is a problem. In the meantime, I think I will leave the IFL disabled and leave the lower pressure at 7 and see how I feel. I used a Puritan Bennett 420E for a year with settings of 4-10 with no problems, so I am used to the lower pressures. My doctor changed the higher pressure to 12 when my new 420 E was staying at 10 all the time, but I am wondering now if the old machine had the IFL off and the newer one had the IFL on and that was the problem. Of course, at that time I didn't know about this forum and all the information available here and certainly didn't know anything about the settings as that was all done by my DME provider. I will keep working on it until I can get comfortable with my machine and hopefully will keep working with my masks to keep the leaks down.

If you have Silverlining reports for those times, you can see the IFL1 satus reported.

10 to 1 your old machine had IFL1 off and the new one had it on. IFL1=1 (on) is the default the machine comes with.

You had many responsed to the same question that you posted last week viewtopic/t37094/I-need-help-with-setti ... -Auto.html - it was on page 2 of the forum just now, so I bumped it up for you in case perhaps you missed all those responses.

Those Hypopneas /cnt mean you had many hypopneas unaccompanied by signs of obstruction - no snores or flow limitation with them.

Hawthrone's right - chaging 2 things at once is a sure way of confusing yourself.

By the way, you can ask to be notified when replys are posted to your questions - in the options area beneath the "save preview submit" buttions. It will be done by email from cpap at cpaptalk, with a link to the first unread reply, and to others too.

Bump, for Terry.
I'll try to make my opinion clear, once again:
Set up you Sandman exactly as you had it when you did well on your 420E and keep it like that for a week.
If the 420E had a minimum of 4, set the Sandman at a minimum of 4.
If the 420E had a maximum of 10 set the Sandman at a maximum of 10.
If the the 420E with which you felt well had IFL1 off, set the IFL off on the Sandman.

And keep it like that for a week, unless you have very clear reasons to change it.

If you think your doctor knows what he is doing, make sure he knows what your IFL1 setting were on the first machine, and on the second the second machine (I understand you yourself are not sure, but the knowledgeable doctor must have checked it and recorded it in your file) . Ask him what he recommends for your IFL setting on the Sandman now, and follow his instructions. If he doesn't know what IFL1 setting you had on the last reports you handed him, then he doesn't know what he has to know about understanding SilverLining reports and setting up Puritan Bennett /Covidien automatic machines.
