Note:
To protect against larger changes in lung compliance, the machine volume should be set higher and Volume Limit
should be added.

Insp Rise

The Inspiratory Rise setting controls the slope of the pressure rise during a mandatory breath. This control is a relative
control with fast being a setting of 1, and slow a setting of 9.
Range:
Default:
The Inspiratory Rise control is not active for TCPL breaths.

Flow Cycle

The flow cycle setting sets the percentage of the peak inspiratory flow (Peak Flow), at which the inspiratory phase of a
Pressure Control, TCPL or PRVC/Vsync breath is terminated.
Range:
Default:
Flow cycling is active for Pressure, PRVC/Vsync or TCPL breaths only.
Note:
If flow cycling is active during a PRVC or Vsync breath flow cycling of the breath can only occur if the target tidal
volume has been delivered. This allows for expiratory synchrony while assuring delivered tidal volume.
Note:
If Flow Cycling is active during a pressure control breath, monitored airway pressures (inspiratory) will be higher than
set when AAC is active. In pediatric and adult ventilation with an inspiratory pressure setting of zero AAC will still
provide an elevated airway pressure, which will compensate for the resistance of the endotracheal tube.

Waveform

During the delivery of a volume breath, flow can be delivered in one of two user selectable waveforms: square wave or
decelerating wave. The default waveform is Decelerating Wave.
Square Wave (Sq)
With this waveform selected, the ventilator delivers gas at the set peak flow for the duration of the inspiration.
Decelerating Wave (Dec)
With this waveform selected, the ventilator delivers gas starting at the peak flow and decreasing until the flow
reaches 50% of the set peak flow.

Demand Flow

Enables and disables the Intra-Breath Demand system in volume controlled ventilation. The default position is on.
