Trends
Displaying lung-mechanics parameters
The patient's resistance and compliance are
calculated using the linear-regression method.
Information on calculations can be found on
page 167.
After a manual inspiration, the display of
waveforms is automatically stopped for one
minute. The waveforms and associated measured
values can be evaluated together.
1 On the main screen, press the Meas key.
2 Press the RC key.
C Dynamic compliance of the respiratory
system
R Airway resistance including the tube
C /C Index indicating if the lungs are being

overinflated. If C
may be overinflated. Can only be used
with ventilation modes without plateau.
Tc Time constant of the respiratory sys-
tem in milliseconds
r Correlation coefficient of linear regres-
sion
If the warning symbol (A) is displayed
next to the value for r, the measured
values may be distorted, e.g., due to a
leakage.
