Compliance Ratio (C
20
/ C)
Compliance Ratio (C
20
/ C), is the ratio of the dynamic compliance during the last 20% of inspiration (C
20
)
to the total dynamic compliance (C).
Range: 0.00 to 5.00
Resolution: 0.01
Accuracy: ± 10%
Respiratory System Resistance (R
RS
)
Respiratory System Resistance (R
RS
), is the total resistance during the inspiratory phase of a breath.
Respiratory System Resistance is the ratio of the airway pressure differential (peak – plateau) to the
inspiratory flow 12 ms prior to the end of inspiration.
Range: 0 to 100 cmH

Peak Expiratory Resistance (R
PEAK
)
The ventilator shall be capable of calculating and displaying the Peak Expiratory Resistance (R

),
which is defined as the resistance at the time of the Peak Expiratory Flow (PEFR).
