Explanation of Modes, Breath Types and Special Functions
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. See figure 7-1A. A descending
ramp flow wave pattern delivers the set flow initially, decreases flow
