Why Operating Theatres Demand More from a Medical Gas System

An operating theatre relies on the same medical gas system principles as the rest of the hospital. What sets it apart is the range of services required and the demands placed on the system.

Higher Design Flows

Theatre pipelines must accommodate demanding peak-flow conditions while maintaining the required pressure at every terminal unit. This includes provision for oxygen flushing and, in some procedures, high-flow surgical air for powered instruments.

More Services and Outlets

Operating theatres typically require several medical gas and vacuum services, with multiple outlets positioned for the anaesthetist and surgical team. These allow several devices to operate simultaneously and reduce reliance on a single terminal unit.

Precise Isolation and Monitoring

Each operating suite is normally provided with dedicated area isolation valves and local pressure alarms. This allows faults or maintenance work to be contained without unnecessarily disrupting other clinical areas.

Engineering for Critical Care

The underlying system is not fundamentally different, but its capacity, terminal-unit provision, alarms and isolation arrangements are designed around the higher operational demands and consequences of interruption within an operating theatre.
