AVEA ventilator systems Chapter 3: Ventilator Operation 93
L2786 Rev. M
Peak Flow
Peak flow is the flow delivered by the ventilator during the inspiratory phase of a mandatory volume or TCPL breath.
Range: 3 to 150 L/min (Adult)
1 to 75 L/min (Pediatric)
0.4 to 30.0 L/min (Neonate)
Defaults: 60 L/min (Adult)
20 L/min (Pediatric)
8.0 L/min (Neonate)
Inspiratory Time (I-Time)
The I-Time control sets the inspiratory time cycle variable for all mandatory pressure, TCPL or PRVC breaths.
Range: 0.20 to 5.00 seconds (Adult/Pediatric)
0.15 to 3.00 seconds (Neonate)
Default: 1.0 second (Adult)
0.75 seconds (Pediatric)
0.35 second (Neonate)
Note:
If the preset I-Time is greater than actual I- Time
(as determined by V
t
, F
P
, and the waveform), an Inspiratory Pause time
equal to the preset I-Time minus the actual I- Time is added to the breath.
Inspiratory Pause (Insp Pause)
Sets an Inspiratory Pause, which will be in effect for each volume breath delivered.
A preset inspiratory pause will be delivered with each volume breath.
Range: 0.00 to 3.00 seconds
Default: 0.00 second
PSV (Pressure Support)
The PSV control sets the pressure in the circuit during a pressure supported breath.
Range: 0 to 90 cmH
2
O (Adult/Pediatric)
0 to 80 cmH
2
O (Neonate)
Maximum Flow: > 200 L/min (Adult)
<
120 L/min (Pediatric)
<
50 L/min (Neonate)
Default: 0 cmH
2
O
Note:
The ventilator will not allow the operator to set a Peak Inspiratory Pressure (Insp Pres or PSV + PEEP, or baseline
pressure in APRV / BiPhasic, greater than 90 cmH
2
O). The ventilator will deliver an on screen Pop-Up Message stating
that the Ppeak > 90 cmH
2
O. The operator must change the Inspiratory Pressure and or PEEP setting to limit the Ppeak
to less than or equal to 90 cmH
2
O.
