My machine is a res med Auto with Cflex in Cpap mode. I would like to give the Cflex a ride but I read somewhere that my original pressure setting of 10 will need to be increased using Cflex mode? If so what should my pressure setting be for Cflex 1,2 and 3?
Cflex setting help needed

C-Flex is ONLY available on Respironics machines. You do NOT need to compensate with the Remstar machines to use Flex settings.
However, if you have a Resmed machine, you only have EPR which only works while in the CPAP mode. For the Resmed machine you ideally should compensate for the EPR setting used if you want to maintain lab found pressure.
For example: If you were titrated at 10 cm in the lab and want to maintain that, you would set your pressure higher than 10 for what ever EPR setting you use, so with a EPR=2 you would bump your pressure to 12 cm, if you use EPR=3 you would bump it to 13 cm.
IT all depends on what type of events were seen at that higher pressure, if the events seen were apnea, you want to set it so the EPAP pressure maintains 10 cm on its lowest exhale pressure (iPAP would be at 13 cm on inhale using EPR=3).
By contrast if you didn't compensate for it and left machine at lab found 10 cm and then used a EPR=3, your pressure effectively drops to 7 cm pressure from what the lab found to be ideal. This means you would get sub-optimal treatment using EPR.
Keep in mind that the EPAP or exhale pressure on the machine is what maintains your airway "splint" for managing apnea. IPAP or inhale pressure is what maintains Flow Limitations and Hypopnea.
With straight CPAP you increase pressure beyond what may be needed to eliminate the apnea in order to take care of any residual FL or Hypopnea. EPR was brought out by Resmed to compete with Respironics patented CFLEX features with no clear warning about what that feature may do to your therapy.

someday science will catch up to what I'm saying...
Yes your right its EPR. So if I increase my pressure from 10 to 12 to compensate for an EPR setting of 2 would that mean my actual pressure on inhaling would remain at 10?
Also while I have your attention(off topic) I have noticed even on Straight cpap pressure of 10 my machine will increase that to for example 10.4 if needed. Is this a normal feature for all Cpaps as my impression was Cpap was a fixed pressure setting

I also have a Resmed Vantage and use the EPR in CPAP mode. Snoredog is mostly right in that to get the full effect if the titrated number while using EPR you need to set your pressure higher. However, I have noticed that it does not need to set it a full cm high for each EPR setting. For example, when I was first titrated at 9 and used an EPR of 2, my 95% pressure was 8.4, so I ended up raising my pressure .6cm to 9.6 and then got a reading of 9.0. I am now using a set pressure or 12 with an EPR of 1 and my 95% readin is 11.8.
I would check your 95% pressure reading with your machine set up as it is. Then, I would adjust your pressure up the difference to maintain your full titrated pressure for most of the night. My guess is that you will only need to raise it between .6 and 1.0cm of pressure to maintain a full 10.
