System compliance
Primus determines the current compliance of the
breathing circuit with filters, hoses, and a Y-piece.
Typical values for the inspiratory system compli-
ance are between 0.5 and 2.6 mL/hPa (mL/
cmH
O).

In volume-controlled ventilation, system compli-
ance is compensated. For this purpose, Primus in-
creases the applied tidal volume on the basis of the
difference between PEEP and plateau pressure in
accordance with the determined compliance value.
Leakage
Leaks are tested in the mechanical subsystem and
in the complete system (see gas diagrams).
