Shazbat's Therapy Thread

RE: Shazbat's Therapy Thread
(09-09-2021, 08:09 AM)Sleeprider Wrote: In comparing new results with old results, your 95% flow limitation has improved from 0.14 to 0.07 which must be a significant relief. Your tidal volume has improved from 340 mL/sec to 400 and the minute vent has gone from 5.38 L/min to 6.0 L/min. This shows you are considerably better ventilated throughout the night.  This has been accomplished while your median pressure has dropped 2-cm from 10 to 8, not to mention the lower exhale pressure which has dropped from 10 to 6 cm-H2O.  So you are breathing better at lower pressure. That sounds like a win, and the most important factor of all is your comfort and how you feel the next day has qualitatively improved.

Moving forward, I think you should increase the minimum pressure to 8.0 and EPR to 3. This should continue the good trends we see in these results and perhaps improve on them.

Thank you. I must admit, I have no idea what flow limitation, tidal volume and minute vent are, but I am pleased when you say my stats are improving ? I will try your suggestions and see how I get on. Do you have a sleep therapist background, or is it through experience?

RE: Shazbat's Therapy Thread
Our wiki has a glossary of terms where all these definitions can be looked at. They are all basic measures of lung function and respiration. For example:
http://www.apneaboard.com/wiki/index.php/Definitions

Tidal Volume - The amount of air that is inspired or expired in an ordinary breath. Usually expressed in milliliters per second (mL/sec). Used with the respiratory rate to calculate Minute Vent. (Minute Ventilation in L/min = (Tidal volume in mL/1000) * (Respiratory rate in breaths per minute)

Flow Limitation is a restriction in the upper airway that reduces the rate air can flow through the airway to the lungs. It appears on your flow-rate graph as a flattened peak. As flow increases, resistance to flow becomes greater and the flow rate flattens out. The reason EPR is working for you to reduce flow limitation is the CPAP machine is actually increasing pressure as you inhale, and that overcomes the airway resistance. A much better explanation can be found at this wiki link. Really a worthwhile read to understand all this. http://www.apneaboard.com/wiki/index.php...limitation

RE: Shazbat's Therapy Thread
Another question/concern please.

Since changing my settings FROM - auto ramp: start pressure of 4: EPR 1 (ramp only) TO auto ramp off; start pressure of 7; EPR 2 (on all the time), I have been waking up with chest/back pain/discomfort, which I assume are my lungs? I also had congestion and coughing this morning.

I have never had these before, is anything to do with the pressure or EPR change?

Probably unrelated to ramp. Sounds like a cold.

CPAP Pressure help
I’ve been using my Resmed Autosense 10 at pressure 7 and EPR 2 for the last few months, getting around 1 event per hour. 

But recently I’ve been getting bloating and occasional soreness in my lungs. So I decided to experiment with the pressure, to find the lowest setting I could use, without increasing my events too much.

For the last couple of nights I set my machine to a minimum pressure of 4 and a maximum pressure of 4, with no EPR the first night and an EPR of 3 the second night.

Both nights I slept fine and my events were only around 2! Why is this and do I need CPAP?

RE: CPAP Pressure help
The minimum pressure of your machine is 4.0 cm, so if that is the minimum and maximum setting, you don't get EPR. EPR can only be available above 4-cm and it will only reduce exhale pressure to 4.0. Since you use Oscar, it would help to see a detailed daily chart to answer your other questions. CPAP at 4.0 is still CPAP, and whatever issues existed before CPAP will likely be there if you quit.

RE: CPAP Pressure help
If your numbers AND you feel good at that pressure - great.  It shows with 4 cm of pressure you have cut down your events not that you do not need it. 

And just a little information. The lowest any pap machine can possibly go is 4. EPR subtracts the EPR (Exhale pressure relief) from the min. So 4 is as low as it can go so the EPR is not doing anything at that setting. Min 4 -EPR 3 is still 4, the lowest it can go.

If you want to use Epr your min would be 7 

So 7-3=4. Or min 6 EPR2 would be 6-2=4

You may want to do that if your flow limits (chart) is high. EPR treates flow limits.

RE: CPAP Pressure help
Thank you.

When using my usual setting of min 7 max 18 EPR 2, my reports always showed the pressure never goes higher than 12. There are Oscar reports for the above setting on my other post if you have a chance to look at them.

But if min 4 max 4 and no EPR works just as well with regards to events as the higher settings, I think it would be better for me, as the lower settings don’t seem to give me bloating and chest soreness.

I will try and post updated Oscar reports on my other post, once I get a chance Smile

Shabbat,
Your two therapy threads have been merged. Please keep all your therapy questions and charts in this thread. Thanks!
