I work at a hospital and was admitting a pt. The IV machine was beeping, so I informed the nurse in case they needed to do anything before I started speaking with the pt. The nurse never came in the room so I started my interview. While trying to obtain the pt signature I bumped the IV machine. I finished my interview and left the room. While washing my hands the nurse finally went back into the room and asked the pt who paused the machine and the pt pointed to me. I would never press the buttons on the machine due to them being hooked up to the pt for a reason, plus I finished my interview with the machine beeping, so there was no reason I needed the machine off. I'm thinking when I bumped it, it may have paused. Or it paused when I left the room and when the nursed entered it cut back on. Can the machine malfunction or pause it self from being bumped?
