[Diagnosis] Clear airway questions
|
RE: Clear airway questions
burping, aerophagia, is more common with higher pressures. after 8 years the ca is obviously not treatment emergent. could be pressure induced, but again after 8 years, not likely. I would be amazed if you don't find better treatment & comfort with a lower exhale pressure. others will help you with settings suggestions.

RE: Clear airway questions
I'd agree with sheepless. Aerophagia can be addressed by a lower pressure, as well as adding comfort. Treatment emergent CA possibly does not apply, but it's not entirely ruled out just lower on the probability scale with you using CPAP for 8ish years. I believe comfort is the ruler by which you edit pressures, with events being second in your case. For comfort and aerophagia, I'd consider changing over the VAuto mode.

RE: Clear airway questions
Mratliff, I have looked at your charts, and it's my opinion we need to completely start over with a new titration in Vauto mode. You are way over-pressurized and and this is resulting in a lot of discomfort and aerophagia. What I'd like to do is to set you up on Vauto mode at a much lower starting pressure, using some pressure support and see if we can resolve your fragmented therapy, comfort issues and learn where you need to be in pressure. Your current settings are essentially CPAP with no pressure relief or pressure support, so we haven't learned much yet other than you have no obstruction or flow limitation at CPAP 20. if you want to try my approach, take the red pill, but if you'd rather remain in this unpleasant ignorant status, just take the blue pill. The red pill follows:
Mode: Vauto EPAP min: 9.0 Max Pressure 20.0 PS 3.0 Trigger: high Cycle: medium Ti Min 0.3 TiMax 1.8 These settings will allow pressure between 12/9 (IPAP/EPAP) and 20/17. I have suggested the trigger sensitivity at high to help resolve your minimal CA events. It simply makes the transition from EPAP to IPAP a little more sentistive. The Cycle sensitivity is default as are the time of inspiration settings. If you try these settings, we will quickly learn your toleratnce for pressure support which is conservatively set at 3.0 cm, and will learn what pressure threshold you need to avoid obstructive apnea. We will learn from your experiment what settings are optimal. You're welcome to take the Blue Pill and I will leave you alone and we can forget this was ever suggested. Please choose wisely.

RE: Clear airway questions
Thank you to Sheepless, Sarcastic Dave and Sleeprider for the great information.
To Sleeprider, I am seriously considering following your recommendations for new tritiation. I am going to wait one night, as I was unable to download data from last night and want to make sure I can do that before trying anything drastic, as we will of course need to look at the results... One thing I should have mentioned, I do wear an oral device (Tap 2) which I have worn all these years... I don't know if this changes your opinion on anything.. thanks again for all your help.....

RE: Clear airway questions - follow up
I have a follow up question..... To those of you who have looked at my numbers,
do my results show a person who is sleeping well? I have very low AHI, but I do not think I am sleeping well. I admit that I have no idea how to read the flow charts or respiratory charts or the others that indicate quality of sleep... Any help or comments will be greatly appreciated.... thanks again...

RE: Clear airway questions
Mike, where did the original setting of fixed 18 come from? Was that recommended by a doctor, or just something you decided to try for yourself? Do you still have your original sleep study report? It might help if you could share that.
The fact you're burping could be caused by swallowing air during the night - this is called aerophagia. Constant high pressure could be a factor in aerophagia. One of the members more experienced in VAuto machines might want to jump in here, but I'd like to propose an experiment...
My hope is that the machine will run at a generally lower pressure (but can go up to 20 if necessary), giving you a more comfortable sleep so you can keep the mask on for longer periods. As an adjunct to this, consider your sleep hygiene - you mentioned earlier that you're frequently woken by the phone - turn it off! Make sure your room is adequately dark, turn off any distracting gadgets (phone, TV, IPad, whatever). Let's see if these suggestions bring some relief.

RE: Clear airway questions
I know sometimes our recommendations often conflict with each other, and I greatly respect Deepbreathing, however I would never start anyone with PS 5 without first trying lower PS. Other than that we're mostly in agreement, however please keep your introduction to Vauto mode to PS 3.

RE: Clear airway questions
No worries SR - I was hoping you or Fred would jump in right about now...
Mike: SR and Bonjour are the bilevel gurus around here and I'll defer to their experience with this type of machine.

RE: Clear airway questions - changed mode
Thanks to all the members for your help....
In the middle of the night last night I changed my settings to VAuto mode and put he pressures at 20 Ipap and 16 Epap. Once I did this no more CA's and AHI of 0. Wow... The respiratory rate changed drastically also. I attach this from last night. Can anyone tell me if this is close to normal? What should the rate be? thanks again for the help.

RE: Clear airway questions
To my untrained eye, the right half probably represents your spontaneous breathing rate or close to it. The left half looks like respiration driven by the machine.
