Can anyone tell me if they've ever heard of a maximum amount of urine to remove at one time during an In and Out Cath? I don't recall hearing a maximum amount of mLs in school but have asked several fellow nurses lately and the consensus seems to be that no more than 1000 mLs should be removed during an I&O Cath at any one time. I've never posted before but see such great info that I thought I'd pose the question to All Nurses.Com. Thanks!
