Not all catheters are the same.


Yes, I have found that they fall into two categories, the kind that
don't stay on, and the kind that don't come off. After too many bad
experiences with the ones that don't stay on, I've switched the the
ones that don't come off.


So, how many weeks can you leave one on before replacement is required?


This is a very important question and I have been including it on all
Biennial Flight Reviews. The correct answer is of course, "it may remain
in place up to but not including the date of the next BFR or until
circulation ceases, which ever occurs first" [14 CFR 91.1444 (6) (ii)].
I also require all students to demonstrate catheter removal
proficiency during 200 foot simulated rope breaks. I find that this
really keeps 'em on their toes.
