Abstract: A consolidated monitoring cable arrangement allows multiple cables extending between a surgical gurney, or other type of patient support platform, and a peripheral monitoring stand to be consolidated into a single cable. The present use of multiple cables has the disadvantage that the region between a gurney and a monitoring stand is cluttered. This can present a hazard to medical personnel, particularly when an emergency situation requires that concentration be focused on the needs of the patient. In a primary form, the subject cable arrangement uses two boxes, one on the gurney and another on the monitoring stand; a detachable cable connects the two boxes. Shorter cables of uniform length are used to connect a patient on the gurney and equipment on the monitoring stand to a respective box. Besides the aforementioned safety advantage, this cable arrangement reduces the expense of frequent replacement of damaged cables.
