Dräger Cato - Adjusting to the Ventilation Mode

Adjusting to the ventilation mode
For »IPPV", »MAN/SPONT« and »SIMV« ventilation
modes
The alarm limits are switched over automatically with the
change of ventilation mode.
In »IPPV« and »SIMV« modes, the »IPPV alarm limits«
alarm mode is automatically activated on the monitor if
the ventilation rate is equal to or greater than 6 breaths
per minute.
The MAN/SPONT alarm limits are automatically activated
for »MAN/SPONT« and the SIMV alarm limits for »SIMV«
mode with a ventilation frequency of less than 6 breaths
per minute.
The currently active alarm mode at any time is displayed
in the status field and flashes for the first five seconds.
The full range of alarms (»IPPV alarm limits« alarm
mode) can be reactivated by selecting IPPV mode or by
setting the ventilation frequency to a value equal to or
greater than 6 breaths per minute.
