Jean Mi,
You could also have an IP creep, which I had once. It increased my PO2 slowly and I had to keep flushing the lungs. I finally found it by using an IP gauge.
Your description of the problem wasn't specific enough. BTW, I use TX18/50 a lot.

I dale,
as for the IP I have an overpressure valve tuned at 11 bars where my ip is tuned at 10 bars, but it could be the orgin of the problem, on the other hane I dived 1 hours arround 40m this morning and noticed no ppo2 peak this time.
as for my problem description what happend is that I had been u/W at 45 meters for 25' running a 1.2 setpoint I had aire in the dil tank when i decided
get down arround 55m, of course my ppo2 buid up, and i the noticed that even with a couple of flushes the ppo2 was still rather high.
I think tht the profile was not really rebreather correct, i should have gone directly to 55m instead of getting down to 45 m for a long time before getting 15m lower.
