ZOLL M Series CCT Defibrillator Rev D - Manual (Page 18)

12 ZOLL M Series Invasive Blood Pressure
When the M Series is turned on, all alarm functions are disabled and the alarm limits are set to their
default values. Any changes to these settings remain in effect until either the settings are changed or 10
seconds after the M Series is turned off.
Setting alarm limits
You can change all the alarm limits using the standard M Series procedures. See M Series
Operator’s Guide for instructions on setting alarm limits.
You can set the alarm limits using the Auto function, or you can choose your own limits (see above
table). The Auto function sets the high limit to 30 mmHg (4.0 kPa) above and the low limit to 20
mmHg (2.7 kPa) below the measured pressure when alarm limits are set.
Enabling, disabling and suspending alarms
You can enable, disable and suspend all IBP alarms using the standard M Series procedures. See
M Series Operator’s Guide for instructions on enabling, disabling, and suspending alarms.
Changing the status of one Pressure channel alarm automatically sets the other alarms for that
channel to the same status. For example, if you enable the Pressure channel 1 systolic alarm, all
other Pressure channel 1 alarms are automatically enabled. Or if you disable the Pressure channel
2 diastolic alarm, all other Pressure channel 2 alarms are automatically disabled.
Setting alarms for one Pressure channel has no affect on the alarms for the other Pressure channel.
Enabling, disabling or suspending IBP alarms does not affect the status of other M Series alarms.
Clearing IBP alarms
An audible alarm and flashing softkey activate when an IBP signal transitions from pulsatile to non
pulsatile. This alarm only functions on IBP channels labeled P1, ART, and PA. The alarm is
triggered when the difference between the systolic and diastolic pressure drops to less than three
(3) mmHg for more than three (3) seconds.
The alarm must be cleared manually.
When the alarm activates, the Clear IBP Alarm display appears as shown in Fig. 14, flashing in
inverse video.:

To clear the alarm:
• Press the Clear IBP Alarm softkey, the display returns to the standard display.
