Imposed Resistance (R
IMP
)
Imposed Resistance (R
IMP
), is the airway resistance between the wye of the patient circuit and the
tracheal sensor.
Range: 0.0 to 100.0 cmH

O/L/sec
Resolution: 0.1 cmH
2
O/L/sec
Note: Requires an Inspiratory Hold maneuver and a tracheal catheter.
Accuracy: ± 10%
Lung Resistance (R
LUNG
)
Lung Resistance (R
LUNG
), is the ratio of the tracheal pressure differential (peak – plateau) to the
inspiratory flow 12 ms prior to the end of inspiration.
Range: 0.0 to 100.0 cmH

O/L/sec
Resolution: 0.1 cmH

O/L/sec
Note: Requires an Inspiratory Hold maneuver and a tracheal catheter.

Peak Inspiratory Flow Rate (PIFR)
The ventilator is capable of monitoring and displaying the actual peak inspiratory flow rate for the
inspiratory phase of a breath.
Range: 0 to 300 LPM (All patients)
Resolution: 1 LPM (Adult/Pediatric)
0.1 LPM (Neonate)
Accuracy: ± 10%
Peak Expiratory Flow Rate (PEFR)
The ventilator is capable of monitoring and displaying the actual peak expiratory flow rate for the
expiratory phase of a breath.
Range: 0 to 300 LPM (All patients)
Resolution: 1 LPM (Adult/Pediatric)
0.1 LPM (Neonate)
Accuracy: ± 10%
