That doesn't look very comfortable, and you use nasal therapy. I think we will hold off on that idea until after your doctor appointment.

Depending on whether mask design allows it, there's the accessory oxygen bleed port you can get that goes between the hose and mask. Would that make any difference? Or has it been tried and eliminated?

RE: My Journey from BiPAP Auto to Aircurve 10 Vauto
Thank you for the suggestion, yes I am hooked up with that type but my O2 is still low. The thought was if it were attached directly to the mask it would not be deluded as much.
RE: My Journey from BiPAP Auto to Aircurve 10 Vauto
The problem with a port between the hose and mask is that oxygen enriched air is exhausted through the vent before it reaches the user. It really doesn't make much difference which end of the tube the O2 bleed is positioned, the oxygen is still diluted at about a 6 to 1 ratio, even without leaks. Another idea I talked about with bonjour was the fabrication of an EERS system with the oxygen bleed integrated into the enhanced expiratory rebreathing space. Normally, this space is used to conserve some CO2 for rebreathing, but with an O2 bleed, it would instead reserve oxygen enriched air and would be much less diluted during inspiration because all the venting of air not used for inspiration would not enter the EERS.
Here is the wiki on EERS http://www.apneaboard.com/wiki/index.php...ace_(EERS) The contemplated modification would plug the vents in the mask with nasal putty, install a Respironics Whisper Swivel II vent at the end of the tube, add a Corr-a-Flex tube, then the oxygen bleed, and attach that to the mask. In Stacyburke's case, the median respiratory cycle is 3.32 seconds, and about 320 mL. At an oxygen bleed rate of 5 L/min, the EERS would receive 184 mL of pure oxygen, enough to displace all expired air. I have not done the math, but this would result in significantly higher O2 at the mask. However, as I said earlier, I'm reluctant to suggest such a radical modification for an individual currently working with his doctor to solve the problem.

OK that makes sense.

Not a good night because I woke up at 4:30 and could not go back to sleep, I have no idea why. Any way I will post last night. Did not tape settings changed to ps5 is only difference. My appointment with the lung Dr. is Monday...
RE: My Journey from BiPAP Auto to Aircurve 10 Vauto
Best results for tidal volume, SpO2 and comfort were with PS 4.4. I just wanted to evaluate the higher PS and see if there was a fine-tuning opportunity. Let's return to that setting that worked.

RE: My Journey from BiPAP Auto to Aircurve 10 Vauto
Will do. Question for you, I have venting on the pillow and at the top where the hose is plugged into the mask. Can I just plug up (tape over) the vents at the top and get more oxygen?
RE: My Journey from BiPAP Auto to Aircurve 10 Vauto
No, I won't advocate that modification. If anything, the vents at the mask could be plugged with Macks silicone earplugs, but the O2 feed needs to be on the mask side of the connector vent, so even that does not solve the issue.
RE: My Journey from BiPAP Auto to Aircurve 10 Vauto
CPAP masks must be vented.
The only time we even suggest that is for EERS where we add a vent. Do not block mask vents.
