[CPAP] Not sure my CPAP is doing any good

Resmed incorrectly calls periodic breathing, "CSR". I would worry about it.

Did you mean NOT worry about it?

[Dormeo]

I’m guessing he meant you shouldn’t worry. But given your first diagnosis of CHF, I’d follow Gideon’s advice and share what he specified with your doctor.

Do you have the option of seeing a different cardiologist? Your current one sounds unsatisfactory. Can your primary care physician refer you to someone else?

[wayneb64]

Possibly but if it's not really CSR and only 'period breathing' does it matter? What can be done about it even if it is CSR? Doesn't sound like there really is a 'cure' or treatment for it out there but maybe I misread.

[Gideon]

Typically CHF ( Congestive Heart Failure) will cause Cheyne Stokes Respiration (CSR) .  
There is nothing we can do with a PAP other than manage your apnea.

So that is what we will do.  Ok?

Step 1: increasing Peep values to improve oxygenation.  We do this by increasing the exhale pressure.  The fluid on the lungs you mentioned implies you have some need.  So two things to do this, I'll summarize later.  Increase min pressure to 7 and reduce EPR to 2

Step 2: reduce central apnea.  The most effective method of this is typically to reduce EPR so set EPR=2.  Note that this will likely increase obstructive events so we will watch for that.

Step 3:. Turn Ramp off.  Your pressures are low so you should not need the ramp.  Also be aware that events that occur during the ramp are neither treated nor reported.  

Step 4: this is optional, increase max pressure.  You are barely touching the max but all in all you are very well managed meaning you have suppressed the events that would have resulted in uncontrolled pressure increases.  Mine is set to the machines max and I never approach it.  Consider at least 15.

In summary

Set min Press=7

Set EPR=2

Set Ramp=Off

Set Max Pressure=15 (optional)

Here is last nights data. I tried the EPR 2 while reading before bed but it was giving me a headache so I put it back to 3. All the other changes were in place, no ramp, 7-15 pressure range. The first couple of OSAs were me holding my breath while getting settled in. The first 'real' one was just before 3 AM and the pressure responded to about 9.  

Around 4 AM some mostly period breathing started until 4:43 and then a series of OSAs brought the pressure up to 12.4 and woke me up. I get woken up every night around this time but it seemed maybe a bit later than normal. My mask was also leaking pretty well at the same time. I was afraid the nasal cushion wouldn't handle the pressure well, it's far more comfortable to me than the pillows which make my sinuses feel weird. (The EPR 2 was also causing the same sinus affect along with the mild headache.)

I had trouble falling asleep after my 5 AM nature call which was odd, tossed and turned and I think I ended up on my back but I did get another good 90 minutes of sleep until the final 30 minutes where I racked up almost all of the events for the night. Need another post to show that data.

[wayneb64]

If not for the final 30 minutes I would have had a pretty good night, any idea why things took such a turn for the worse at the end? Three OSAs drove the pressure up to 10.5 but then the machine decided the rest were all CSAs.

Is the leak rate in the same units as the pressure? Is it saying almost all the pressure is being leaked out?

EDIT: I just discovered the oximetry import feature of OSCAR but I see that it does not accept a CSV from O2 ring, is there any chance support could be added for that?

OSCAR will import the binary file. If you are using iOS then just export the binary file to your computer and import it into OSCAR. Android seems to be a little more involved but it can be done.

[wayneb64]

I have an Android phone and I can plug the O2 Ring into my PCs USB to use it's PC application to read the data, will the device scan in OSCAR see my USB attached O2 ring?

Is there a guide somewhere on how to do this?

Thanks

See if this helps.
