Philips Trilogy Evo Universal Instructions For Use Manual page 18

Mixed modes: breaths are spontaneous, assist-control, or mandatory.
• S/T: Spontaneous/timed ventilation – spontaneous breaths with pressure support and mandatory breaths with pressure control
•
SIMV-PC: Synchronized intermittent mandatory ventilation (pressure control) – spontaneous breaths with pressure support, assist—
control breaths and mandatory breaths with pressure control
•
SIMV-VC: Synchronized intermittent mandatory ventilation (volume control) – spontaneous breaths with pressure support, assist—
control breaths and mandatory breaths with volume control
Low Tidal Volume Therapy
For low tidal volume therapy, use the infant/pediatric external flow sensor. See the instructions included with the sensor.
When setting volumes greater than or equal to 50ml, use any circuit type.
When setting volumes greater than or equal to 35ml, use either the active flow or dual limb circuits.
The following pressure modes are available for patients who require a tidal volume less than 35ml:
•
A/C-PC
•
PSV
• S/T
•
SIMV-PC
Therapy Mode Comparison Table
For all modes, the breath type varies based on time of patient inspiration. The breath type is always ventilator-initiated and mandatory when the
Trigger Type is set to Off.
