Dräger Cato - Activate and Deactivate CO 2 Alarms; Auto Set;Ventilation Alarm

Activate and deactivate CO2 alarms
In »MAN/SPONT« monitoring mode, the alarm limits for
inspiratory and expiratory CO2 are deactivated; only the
CO2-apnoea alarm is active. This alarm can also be
deactivated by pressing the »CO2 al. on/off« key.
In this case, there will be no CO2 monitoring at all.
The CO2-apnoea alarm can be reactivated by pressing
the key again.
The CO2 alarms are automatically activated on changing
to »IPPV« or »SIMV« monitoring mode with a ventilation
rate above 6 breaths/min.
The alarms remain deactivated when changing to »HLM«
mode or »SIMV« with a ventilation rate of up to 6 breaths
per minute.
When the CO2 alarm is activated, the inspiratory CO2
concentration of the breathing air is monitored with an
invariable upper limit of 5 mmHg.
Auto set/Ventilation alarm
Prerequisite:
The ventilator must be in »IPPV« mode
The ventilation alarms with new alarm limits can be
automatically adjusted to the current ventilator settings
by pressing the softkey »auto set vent. al.«.
The alarm limits previously set in the »limits« menu are
erased and cannot be reactivated! See also »Alarm
concept« on page 65.
The new tolerance ranges generated for the current
measured values depend on the parameter in question:
The default alarm limits are not affected by Auto set and
can be reactivated at any time via the functions »config«,
»warning« and »defaults«.
