For three decades, intensive care patient monitors connected to central stations via point-to-point RS-232 serial cables, limiting bandwidth and preventing dynamic medical device cooperation. This case study details the clinical deployment of IEEE 11073 SDC over hospital Ethernet, connecting multi-parameter monitors, syringe pumps, and ventilators into a unified digital care team.
Serial cables lack galvanic isolation, require manual baud-rate configuration, and offer zero data encryption. Ground loops in older hospitals frequently induced noise spikes that corrupted vital sign trends.
With SDC, bringing a transport monitor into an ICU room immediately establishes zero-configuration discovery, transferring patient historical records and synchronizing alarm thresholds across bedside displays.
