9.3.4 APNEA mute
Induction and certain emergency situations
might warrant the possibility to turn off the
audio signal of alarms associated with
breathing and breathing parameters.
This is achieved by the 'APNEA mute' function.
The function is by default enabled in the
startup configuration settings, see Chapter 9,
page 175. An activation button is thus visible
in the alarm profile window. From there,
APNEA mute can be activated and deactivated
at any time.
The following alarms are affected:
• FiCO
2
: High
• EtCO
2
: Low
• EtCO
2
: High
• Respiratory Rate: Low
• Apnea
• Apnea > 60 s / Apnea > 120 s
• Expiratory Minute Volume: Low
• Leakage
The APNEA mute function can be used in all
ventilation modes. It is automatically
deactivated by switching from MAN to AUTO,
AUTO to MAN, or when going to standby
mode.
'APNEA mute' and 'HLM mode' (CPB mode)
cannot be active simultaneously. Selecting
either in the alarm profile window, prevents
the other from being activated.
