Descriptions of Primary Breath Controls
Breath Rate (Rate)
The breath rate control sets the breath interval. Its function is dependent upon the selected mode of ventilation and it has
different effects on the breath cycle, depending on which mode is selected.
Range: 1 to 150 bpm (Neonate / Pediatric)
1 to 120 bpm (Adult)
Breath Interval: (60/Rate) sec.
Defaults: 12 bpm (Adult)
12 bpm (Pediatric)
20 bpm (Neonate)
Tidal Volume (Volume)
A volume breath delivers a predetermined volume of gas to the patient. Tidal Volume, together with the Insp Flow, and
Waveform settings determine how the volume breath is delivered.
Range: 0.10 to 2.50 L (Adult)
25 to 500 ml (Pediatric)
2.0 to 300 ml (Neonate)
Defaults: 0.50 L (Adult)
100 ml (Pediatric)
2.0 ml (Neonate)
Sigh: 1.5 x Volume (Adult/Pediatric only)
Note:
When operated from the internal compressor, the maximum Tidal Volume that the ventilator can achieve is 2.0 L.
The maximum minute volume that the ventilator is capable of delivering using wall gas supply is at least 60L and using
internal compressor is 40L.
Inspiratory Pressure (Insp Pres)
During a mandatory pressure breath, the ventilator controls the inspiratory pressure in the circuit. For Pressure & TCPL
breaths, the pressure achieved is a combination of the preset Insp. Pres. level plus PEEP.
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: 15 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.
