My Journey from BiPAP Auto to Aircurve 10 Vauto

If it helps, I think the Daily tab then to Events tab within gives the Time slider to get 2 Min. easily.

Thanks Thank you, I have set it to 4 and I will give you the pictures again, enlarged.

Thank you Dave, it is much easier when you do that!

RE: Newbe First time using BiPAP Auto mode
No change in advise from the improved images.  If you want to I want to be sure you understand what this flow rate chart means. I'll interpret the second one starting at 04:31:10, which is a fairly normal breath form.  At 04:31:20 there is a misshapen peak on inspiration flow. It starts to rise, then quickly flow rate drops due to airway restriction or obstruction.  This reduction in flow occurs in spite of increasing physical effort to inhale, causing the inhale time to become longer. there is another smaller
breath then we see the flow limitation flag on a failed inspiration that would have been an OA if it lasted 10 seconds.  The breath after the FL is severely flow limited and is followed by a number of less severely flow limited breaths.  These are important because of the respiratory effort that causes arousal and actually lowers the volume of respired air.  Pressure support should be helping to reduce this effort and normalizing flow.  With a Resmed bilevel we can see a mask pressure chart that shows how pressure changes on a breath by breath basis.  I'll add an image that shows the mask pressure on a Resmed Autoset CPAP so you have an idea of how pressure support gets behind inspiration to prevent flow limitation.  This example is just the CPAP and works just like the Aircurve bilevel, and in this case is providing a full 3-cm of PS which is out-performing your Philips Dreamstation BiPAP set to PS 3.5 to 5.0.

RE: Newbe First time using BiPAP Auto mode
Here is last nights.  CA is down but a lot of flow limitations.  Also the pressure was at the max for a long time, with what I guess is mouth breathing...  What are the gray areas, one at the start of the night 16 other times?

RE: Newbe First time using BiPAP Auto mode
Last night again my flow rate has a number of grayed out places in the flow rate, what are they?  The pressure shows that I am at max pressure for 3 periods of time, do I need to raise that?  Over all how does this look?

2 pictures, one the whole night the 2nd is one of the gray parts.

RE: Newbe First time using BiPAP Auto mode
The Philips Respironics machines show variable breathing with a pink or gray shaded area. This is not an event but a variation in flow rate that oscillates but does not qualify as periodic breathing or CSR. Philips uses the variable breathing signal in its auto CPAP and BiPAP algorithms to increase, decrease or maintain pressure, dependent on the antecedent condition when VB is detected. Under the heading of TMI, I actually wrote a wiki on this topic http://www.apneaboard.com/wiki/index.php..._Breathing

This event may or may not be useful to you since there is little you can do about it. You can turn off the Variable Breathing in the OSCAR preferences if you'd rather not see it. Otherwise, it suggests somewhat unstable breathing, and is a pretty good indicator of approaching the apneic threshold if central apnea are an issue.

RE: Newbe First time using BiPAP Auto mode
Last night was not a great night, woke up and could not go back to sleep from about 3:15 to 5.  My question is looking at the pressure graph there are a lot of times my pressure is at max.  Should it be raised?  2nd. question, does the leak rate still show mouth breathing?  I don't think I am but my mouth is very dry, to point of my mouth sticking to my teeth when I wake up.  This happens 4 to 6 times a night.

RE: Newbe First time using BiPAP Auto mode
Your maximum IPAP pressure is about 17 and the settings allow 18. Increasing the max pressure is not a problem because in theory the machine only increases pressure as high as is needed to maintain the PS difference between IPAP and EPAP. There is nothing to suggest EPAP needs to be at 11.0 and I see a potential need to try PS min at 4.5. I think it might help to get a look at the advanced view (View/Reset Graphs/Advanced), which would let us see how your tidal volume and minute vent are responding to pressure.

I'd like to try:
EPAP min 10.0
PS min 4.5
PS max 5.5
Max pressure 18.0

I still don't think you will bounce off the max pressure allowed but the increase in PS may help with the tidal volume. I'm trying to move pressure down to a more comfortable range and have not seen any OA that suggests the need for the current pressure of 11.0. The increase in PS min should continue to help with residual flow limitation, which remains a prominent feature in your charts.
