[CPAP] Help with oscar
#41
RE: Help with oscar
I went back and checked all other charts you posted. This is the first time we have seen a central apnea group. I would have disregarded it entirely but the periodic breathing looked like Cheyne-Stokes Respiration. The Aircurve 10 Vauto is by far the best machine for treating obstructive sleep apnea, and this cluster of CA and periodic breathing was completely unexpected.

RE: Help with oscar
BiPAP or bilevel therapy can increase ventilation and actually make you more prone to periodic breathing and CSR. In most individuals without heart failure, this breathing pattern is just a feedback loop caused by alternating hypercapnea and hypocapnea (excess and insufficient CO2). It is CO2 that causes respiratory drive, and sometimes with CPAP or bilevel, ventilation is increased enough to flush the CO2 from our respiratory system. This causes a reduction in respiratory effort and the flow rate diminishes until you briefly stop breathing, at which point CO2 rapidly increases and respiration restarts, but due the the lag respiration becomes greater than normal again purging CO2 and the cycle repeats. You can see at the end of the sequence you posted, the oscillations are diminishing and eventually level out and normalize. This is essentially passing in and out of your apneic threshold.

This is a rather complex article explaining the feedback loop, and how CA can arise out of the imbalance of CO2 in some individuals, and this is not predicated on central nervous system disorders, spinal injury or heart failure. https://physoc.onlinelibrary.wiley.com/d...004.028985 It's good information, but the simple solution may be to increase CO2 just enough to avoid the loop. We have a wiki for that. Enhanced Expiratory Rebreathing Space http://www.apneaboard.com/wiki/index.php...ace_(EERS) Basically we just allow you to rebreathe a small amount of exhaled air to maintain CO2 by moving the mask vent upstream towards the CPAP machine a short distance, and using the created dead space for re-breathing.

RE: Help with oscar
I got all the parts ordered to build my EERS. I had to order from several different suppliers but all parts should arrive within 7 days. I will let you guys know how it goes.
Thanks again for all the help.

RE: Help with oscar
Brent, please feel free to document your EERS build with images and charts that show what you're trying to accomplish, and your progress. I will add it to the Wiki. It is not a common setup, but has been mostly effective for those that need it.
