Function Description Savina Version 2.0
Flow sensor S1 measures the inspiratory gas flow. Its measurement variable serves as
for calculation of the necessary oxygen flow and thus to operate the oxygen flow control valves
V7.1 to V7.8, to control the mandatory breaths and to monitor the functions of the unit. The sensor
includes a temperature measurement function to measure the inspiratory gas temperature.
Flow sensor S2 measures the flow via the expiratory valve to the outlet. The flow sensor used is
the Spirolog sensor from the Evita series (temperature-compensated hot wire flowmeter with no
detection of flow direction). The signal is used for patient monitoring (e.g. minute volume
monitoring) among other applications.
