Those red, white and black leads fall off all the time, triggering a "Code Blue" in her ICU room. Usually it's just because the whore nurse swiped a fly across her face a disconnected a few of them.
FWIW, those are different leads, different connectors, and are connected to a different type of machine and she almost certainly wasn't in an ICU.
I concur with the previous poster as the most statistically likely scenario based on the limited info avail from that photo. Happens every day and it is indeed a waste.
