Theory of Operations
A-2
Service Manual
The exhalation system is heated to prevent moist exhaled gas from condensing in the exhalation
pathway. A bacteria filter should be used at the From Patient port to prevent contaminants in the
exhaled gas from entering the exhalation system and contaminating the exhalation valve and flow
sensor. Another filter should be placed at the To Patient port to prevent contamination of the
inspiratory manifold when the emergency relief valve opens (in the case of a Device Alert alarm,
Both Air/O
2
Supply Loss alarm, or Sustained High Baseline Pressure alarm that is accompanied by a
blockage of the exhalation valve).
The heated exhalation system features an active exhalation valve with a low exhaled flow resistance
for rapid return of circuit pressure to baseline and decreased potential for auto-PEEP.

* Not available on the S model
A.2.1
Volume Control
Volume Control ventilation provides time-cycled, volume-limited mandatory breaths.
Volume
and
Flow
(or inspiratory time) are user-set parameters and pressure is allowed to vary. The user has the
option to select between two flow wave patterns for breath delivery in volume ventilation. The flow
wave pattern function is accessed via the
Advanced
data set.
A square flow wave pattern delivers the set flow constantly until the set tidal volume is delivered.
