The design parameters for internal spaces should be found in the detailed room-requirement sheets published in
the individual IUSS guidance documents of the various functional units. Where these room-requirement sheets are
absent or lacking adequate information, the data contained in this document may be used.
All units of a health establishment, except sub-acute and hospice facilities, where patients are accommodated and
treated, must have medial gases and vacuum provided by medical-grade piped services, with indexed terminal
connecter points. Bottle systems may be provided in sub-acute and outpatient facilities.
Mobile gas services must be available for crisis situations.
Sub-acute facilities must have one mobile oxygen cylinder per 10 patients and one suction machine for every 10
patients.
The minimum services to be supplied to all acute care areas are described in Table 11.1. Should the data in this
table be in conflict with the table presented in the individual departmental design guidance documents, those
individual guidance documents take precedence.

A gas alarm system to monitor gases, excluding scavenging, must be installed in a location that is manned 24 hours
per day. A slave panel must also be installed in the intensive-care unit and in the theatre complex. This alarm
system must be connected to UPS.
All piped vacuum and oxygen systems must have mobile back-up systems with adequately trained staff to handle
them. The back-up service shall be automatically activated if the line pressure drops below the set operating
pressure. All back-up services and change-over valves shall be on UPS and diesel generator supplies.
Medical air (low pressure) for respiratory purposes must be provided at a fixed pipeline pressure of 400 kPa.
Medical air (high pressure) for driving surgical power tools must be provided at a terminal usage pressure between
700kPa and 1000 kPa, depending on the tools/equipment to be used. The ICU and operating rooms must be
cases where a second pendant is installed, the services in the theatre panel can be omitted.
