A modern operating room is far more than just a room with an operating table and lighting. It is a highly complex, technical ecosystem in which numerous devices, systems, and people must work together simultaneously. Every step is designed for precision, and any delay can disrupt the process – and, in the worst case, compromise patient safety. One of the often underestimated but central foundations of this system is the medical gas supply. Oxygen, medical compressed air, CO₂, or nitrous oxide must be available at all times reliably, safely, and in precisely metered doses. At the same time, their provision must not hinder the workflow or create additional risks. This is precisely where the limitations of classic wall connections become apparent. They are permanently installed, only accessible to a limited extent, and often force the OR team to compromise on positioning, freedom of movement, and ergonomics. In an environment that demands maximum flexibility, such rigid solutions increasingly seem like a relic of past OR concepts. Modern pendant systems offer a contemporary answer to these challenges – and change the way medical gases are provided and used in the OR.
