I'm assuming that some people get relief at 4 vs. 0. I know I was really suffering at 8 vs. 11.SleepingUgly wrote:That is true if one assumes that 4cm is a therapeutic pressure. Certainly it's a pressure that can do something for some types of respiratory events, but I don't know if it's a therapeutic pressure for an obstructive apnea. It may eliminate hypopneas and relegate them to FLs or something. Who knows.Also, just because you don't have any apneas at 4 cm doesn't mean you won't have any apneas without CPAP.
I've never seen a nasal pillow or nasal mask with an anti-asphyxiation valve, but there may be some.SleepingUgly wrote:Interesting. I didn't know that. I didn't even know there wasn't an anti-asphyxiation valve on a nasal pillow mask, either, so I guess I don't know much about how to not asphyxiate myself.Modifying the machine to go below 4 cm is theoretically dangerous due to CO2 accumulation. It would be dangerous even with a full face mask or oral mask with an asphyxiation valve. The asphyxiation valve works at 0 pressure. It might not work at 1 cm.
As I understand it, an XML file is a method to provide parameters to a software program. The s/w has to have been written to look for and accept specific data from the xml file. If the s/w isn't looking for it, it's presence in the xml will have no effect on the s/w.datguykirt wrote:Has anyone tried using the CPAP with no pressure to get a base line reading to use as a comparison to gauge the effectiveness of the treatment? Mine (S9 Elite) only goes as low as 4 cm H2O but I suspect that would be controlled by altering the XML file, ResScan.XML
Any thoughts on this?
Would not a pressure of 0 mean that NO air at all would come throught the hose?datguykirt wrote:Has anyone tried using the CPAP with no pressure to get a base line reading to use as a comparison to gauge the effectiveness of the treatment?Any thoughts on this?
Your lungs would drive air back through the CPAP machine and would suck air back up the hose. There is some resistance, but you can do it. Unplug your mask some time, stick the hose in your mouth and breathe in and out through it.StevenXXXX wrote:Would not a pressure of 0 mean that NO air at all would come throught the hose?datguykirt wrote:Has anyone tried using the CPAP with no pressure to get a base line reading to use as a comparison to gauge the effectiveness of the treatment?Any thoughts on this?
