Perhaps Mel is right, but I've had 4-5 life threatening situations with CO2 over the past 5 years and only one had anything to do with the sorb or the scubber.
All were retention issues. There was nothing wrong with the scrubber and it was in perfect working condition every time but one. She is probably right there. If you scrubber is gonzo, you'd perhaps be taking in CO2 and feeling the effects before it was reflected in the end-tidal or your exhalations.
How retention would reflect in a monitoring device is also unknown to me. Bad breathing habits, loop management, and WOB issues almost got me. Would that retention and rising blood percentages be reflected instantly in the end tidal numbers or would there be some sort of lag. And what percentage of the normal end tidal numbers would an issue look like?
From what I have read regrading CE tests, the scrubbers clean out ALL the CO2 right from the get go. There is no need to "warm up". Unless they are compromised there should be no CO2 in the inhale lung or side of the loop.
