Dräger Primus - Ending the External Fresh-Gas Mode

Ventilation
Display (example):
The airway pressure PAW and the Ext. Outlet
mandatory frequency Freg., PPEAK and
PMEAN are measured at the external
fresh-gas outlet.
Pressure measurement may be impaired
by activating the O2 flush or O2
emergency delivery.
The minute volume MV and tidal volume
VT are not measured.
@ Set the fresh-gas flow. The fresh-gas
supply must be equal to at least twice
the minute volume in order to exclude
rebreathing.
Certain alarms are disabled
automatically in order to avoid artefacts,
see table on page 97.
Caution! Ambient air may become
contaminated with anaesthetic
agent when using non-rebreathing
systems.
Excess fresh gas can be discharged into
the anaesthetic gas scavenging line via
the breathing system of Primus. For this
purpose, the non-rebreathing system
must be connected to the Y-piece of the
breathing hoses connected to the
breathing system.
