Factor of spontaneous breathing (ratio of the minute vo-
lume of spontaneous breathing to the total breathing vo-
lume)
MVe_sp / MVe
6.4.
Resistance to the exhalation (total airway resistance
during exhalation)
Rexp

6.6.
Resistance of the breathing circuit, measured in the cir-
cuit test
Rcirc
6.7.
Compliance of the breathing circuit, measured in the
circuit test
Ccirc
6.8. Compliance Cdyn
6.9.
Rapid shallow breathing index (dimensionless parame-
ter characterizing the depth of patient’s breathing)
RSBI
7. Graphical monitoring
7.1.
Number of curves simultaneously displayed on the
screen
1, 2, 3 or 4 selected by the user
7.2. Displaying of spirometry loops
Simultaneous display of 3 curves and 1 loop
at the user's choice. Ability to save ("freeze")
the reference loop and to the store the mo-
ment of saving. Analysis of the main para-
meters of the respiratory cycle.
