The following table gives the options and ranges for the Vt parameters:
PIP (Peak Inspiratory Pressure) -- Pressure Management
In volume targeted modes, the primary field shows the delivered PIP as outline text. In pressure
targeted modes, the PIP target is displayed and is adjustable. The PIP High Limit, PIP Low
Limit, and PEEP are also available as secondary parameters.
During the exhalation phase, the ventilator opens the exhalation valve when the pressure is
above the PEEP setting, and closes it when below the setting.
In Bilevel Ventilation Mode, the ventilator provides noninvasive ventilation with the ability to
manage the patient by adjusting the IPAP and EPAP parameters.
Caution
Set the trigger level to minimize the work of breathing for the patient and prevent
auto-triggering. Set the Vt alarms to bracket average tidal volume so that the unit detects pending
respiratory failure (low tidal volumes) and excessive leaks (high tidal volumes).
Spontaneous/Assisted Breath Trigger
The Spontaneous/Assisted Breath Trigger is preset to -2.0 cm H2O and can be adjusted from-
6.0 to -0.5 cm H2O below the baseline (PEEP) pressure. In order to initiate a spontaneous or
assisted breath, the patient must generate -2.0 cm H2O. When the pressure drop is detected, an
assisted breath is delivered.
The trigger automatically adjusts when the PEEP is changed.
