1.4 Brief description of
the system
The integrated anesthetic workstation Zeus includes the following compo-
nents:
– Windows NT computer with system display unit for operation of therapy
control and monitoring
– electronic gas and anesthetic agent flow control with closed-loop control
system
– electronically controlled and driven blower with rebreathing system
– airway monitoring
– hemodynamics monitoring module
The following extensions are available as optional features:
– Dräger syringe pumps for intravenous anesthesia
1.4.1 Configuration The Zeus anesthesia workstation can be subdivided into the display and con-
trol unit HERMES and the anesthetic gas box (A-Box).
HERMES is a PC based system for display and control of the A-Box or other
connected front-end units, such as the parameter box for measurement of
hemodynamic values. In addition, HERMES provides all external interfaces
of the Zeus anesthesia workstation, e.g. printer and serial ports.
The anesthetic gas box (Figure 2) contains the actuators required for the sys-
tem, the mixed-gas flow control, the anesthetic-agent flow-control, the breath-
ing system, the lung ventilator and the monitoring system. The anesthetic gas
box also comprises slots and interfaces for future optional features.
1.4.2 The most important
external characteristics
The anesthetic workstation Zeus has an excellent ergonomic design. This
includes, for example:
– A system display unit mounted on a hinged arm that allows a 180° rota-
tion. A second flat display (optional feature) can be arranged on top of the
system display unit.
– A housing shape that is suitable both for left-hand/right-hand operation.
This includes, besides the rotatable system display unit, a push-through
work top and a push-through drawer. The absorber can be viewed easily
from both sides.
– Concealed, left-hand and right-hand rails for mounting of accessories.
– O2 flush buttons that can be operated on left-hand side and right-hand
side.
– A central locking brake for trolley castors that can be operated from both
sides.
