Displaying Lung Values; Displaying Measured Volume Values - Dräger Babylog 8000 plus Instructions For Use Manual

Displaying lung values

The Babylog 8000 plus calculates the resistance and compli-
ance of the patient's lung using linear regression analysis.
In the monitoring menu, press the keys »Meas« and »RC«.
R = resistance of the airway, including the tube
C = dynamic compliance of the respiratory system
TC = time constant of the respiratory system in
milliseconds
C /C = index which indicates overdistension of the lungs:
20
C /C <0.8: lungs may be overdistended.
20
This can only be used with ventilation modes
using no plateau (see page 127).
r = correlation coefficient of the linear regression
analysis
See page 127 for calculation of the parameters.
After manual inspiration, the display of the ventilation curves
is automatically frozen for one minute. The curves and the
related measured values can then be assessed together.
Switching curves: see page 57.
Cancelling the "freeze" function: see page 58.
CAUTION
If the warning symbol is displayed beside the value for »r«,
the measured values may be false due, for example,
to a leak.

Displaying measured volume values

In the monitoring menu, press the keys »Meas« and »Vol«.
Display (example):
MV = expiratory minute volume
spont = spontaneous breathing component of the minute
volume (in %)
Leak = Leak in the tube (see the description in the
appendix, page 125.
VT = expiratory tidal volume of the preceding breathing
cycle
