Section 5 - Operation
Respiratory Volume Monitoring
REVERSE FLOW
(Advisory)
If a reverse flow through the sensor in excess of 20 ml is detected, the
Advisory message REVERSE FLOW appears on the central alarm display
and a single-tone audible alarm sounds.
A forward flow greater than 20 ml clears the alarm condition. The
REVERSE FLOW alarm message remains on the screen for 10 seconds
after the resumption of forward flow to enable you to recognize an
intermittent reverse flow condition.
VOL SENS DISC
(Advisory)
If the respiratory volume sensor cord is not properly connected to its
input receptacle on the anesthesia machine (or if the cord is damaged
enough to cause an open circuit), the Advisory messages VOL SENS
DISC and VOL ALRM OFF appear on the central alarm display. The
digital and bar graph display areas also go blank. Reconnecting the
sensor cord clears the alarm condition.
VOL ALRM OFF
(Advisory)
When the volume alarms have been disabled, the Advisory message VOL
ALRM OFF appears on the central alarm display. This alarm condition is
also generated by a disconnect of the sensor cord.
VOL ALARMS
STBY
(Advisory)
When the volume alarms have been set to Standby, the Advisory
message VOL ALARMS STBY appears on the central alarm display.
