  • Cable clutter is a recognizable problem for many users in a home context or an office context. Cable clutter is also a problem in intensive care units and other medical contexts. Whereas cable clutter in a home or office may be a nuisance, cable clutter in intensive care units and other medical contexts presents a danger. In many situations, multiple independent cables may be placed on or around a patient, and this presents a danger along with workflow and efficiency concerns. Confusion due to cluttered cables may make it difficult or even impossible to use some equipment in intensive care units and other medical contexts. Similar concerns are present outside of medical contexts, such as in the home context or office context.
