There's bound to be condensation (rainout) (it's the laws of physics). Isn't there a water trap in there somewhere (or am I missing something here)? Do you have details of the set you are using (supplier, catalogue number, etc.)?

I assume (should I ever assume .... but you're using the phrase long cases) that you're referring to anaesthesia here KAG, rather than ICU?

I also hear the term exhaled breath condensate (EBC) being used. Is that what we are talking about?

HME: hygroscopic heat-moisture exchanger? I always thought these should not be used in anaesthesia circuits (?)

Meanwhile, here's a link for anyone else who may be interested. smile
