I have a dr's order to irrigate foley catheter with 100-250 ml's ns. the pt has a 3-way catheter (to be specific-the tubing extending from his penis has 3 lumens, with 2 2-Liter bags ns infusing into catheter) which lumen do I irrigate? common sense would say the lumen that the cbi bags are draining saline into the bladder/penis. I almost thought I should irrigate the middle lumen (the one that drains into the foley bag, but thought about it and I don't think that's the right one.) I know someone will be able to give advice here. Thanks in advance.
