Dräger Narkomed 2B - Respiratory Volume Alarm Messages

Section 5 - Operation
Respiratory Volume Monitoring
Respiratory Volume
Alarm Messages
The following list contains all warning, caution and advisory alarms
associated with respiratory volume monitoring.
APNEA-VOL
(Warning/
Caution)
The Narkomed 2B continuously monitors the expiratory flow in the
patient breathing system. By processing the expiratory flow pattern, the
monitor can determine if a “valid” breath has occurred. A “valid” breath
has a tidal volume of 80 ml or greater.
If a valid breath is not detected for an interval of 15 seconds, a red
APNEA LED indicator lights continuously, the Caution message APNEA-
VOL appears on the central alarm display, and an intermittent audible
alarm sounds.
If a valid breath is not detected for an additional 15 seconds (30 seconds
total), the red APNEA LED indicator flashes on and off, the Caution
message APNEA-VOL is upgraded to a Warning on the central alarm
display, and a continuously repeating audible alarm sounds. Also, the
display area pertaining to the Respiratory Volume Monitor goes blank.
When a valid breath is detected, alarm annunciation ceases and a tidal
volume measurement appears in the display window. However, a full
minute of respiratory activity must be registered before the minute
volume and respiratory rate appear.
NOTE: Volume-related alarms can be disabled with the VOLUME
ALARMS DISABLE key.
MIN VOL LOW
(Caution)
Whenever the Narkomed 2B measures a minute volume less than the
minute volume low alarm limit, the Caution message MIN VOL LOW
appears on the central alarm display and an intermittent audible alarm
sounds.
