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.
