Technical data
15.14 Display of calculated values
Enflurane 0 to 6 Vol% (kPa)
Isoflurane 0 to 5 Vol% (kPa)
Sevoflurane 0 to 10 Vol% (kPa)
Desflurane 0 to 20 Vol% (kPa)
Information The following calculated values are partly based on
measured values from various sensors with different
measurement accuracies. Due to the combination of
these measured values, the resulting accuracy of the
calculated values may be reduced.
Airway parameters
Dynamic compliance Cdyn
Mean dynamic compliance Cdyn mean
Range 0 to 200 mL/hPa (mL/cmH
2O)
Accuracy ±15 % of the displayed value or ±1 mL/hPa (cmH
2O)
(the greater value applies)
Resolution of displayed value 0.1 mL/hPa (mL/cmH
2O)
Information The values may be distorted by spontaneous breath-
ing, thus reducing the measurement accuracy.
Resistance R
Range 0 to 100 hPa/L/s (cmH
2O/L/s)
Accuracy ±30 % of the displayed value or ±3 hPa/L/s
(cmH
2O/L/s) (the greater value applies)
Resolution of displayed value 1 hPa/L/s (cmH
2O/L/s)
Information The values may be distorted by spontaneous breath-
ing, thus reducing the measurement accuracy.
Elastance E
Range 0.005 to 10.000 hPa/mL (cmH
2O/mL)
Resolution of displayed value 0.001 hPa/mL (cmH
2O/mL)
Information The elastance E is calculated as 1 / Cdyn mean.
Time constant TC
Range 0.0 to 5.0 s
Resolution of displayed value 0.1 s
Information The time constant TC is calculated as R x Cdyn mean.
Leakage
Difference between inspiratory and expira-
tory tidal volumes ∆VT
Range 0 to 2500 mL
Accuracy ±20 % of the displayed value or ±30 mL (the greater
value applies)
Resolution of displayed value 1 mL
