1. A system for detecting and monitoring lines in a healthcare setting, the system comprising:
a medical device positioned in a healthcare facility,
a line extending from the medical device,
at least one imaging device positioned in the healthcare facility and separate from the medical device, wherein the at least one imaging device detects the line and identifies the line, and
a computer device having a processor and executable instructions stored on a non- transitory computer readable medium, wherein the execution of the executable instructions configures the processor to;
analyze an image of the line from the at least one imaging device to determine whether an unwanted condition of the line has occurred,
segment the image to remove any portions of the image that do not include the line,
trace a path of the line with a curvature analysis algorithm that fits the path to a curve of appropriate order, and
determine whether the unwanted condition of the line has occurred based on the curve.
