Nurse experiment: how much water can a fecal management system (FMS) balloon actually hold? In this video, Nurse Sarah puts an FMS system to the test. The FMS used in this video was rated at 45 ml. In clinical practice, you should always follow your facility protocols and manufacturer's instructions, and never overfill a balloon or misuse a device. In another short, Nurse Sarah tested a 5 ml Foley balloon. See more fun shorts here: https://www.youtube.com/watch?v=Z7yZTwhTF4I&list=PLQrdx7r
