4.5 Parameter Alarm
The setup for parameter alarms is in their menus. In the menu for a specific parameter, you can check
and set the alarm limit, alarm status. The setup is isolated from each other.
When a parameter alarm is off, a symbol
individually, they must be turned on individually.
For the parameters whose alarm is set to ON, the alarm will be triggered when at least one of them exceeds
alarm limit. The following actions take place:
1. Alarm message displays on the screen as described in alarm mode;
2. The monitor beeps in its corresponding alarm class and volume;
3. Alarm lamp flashes;
4. Store all parameter values during the alarm and 4,8 or 16 second waveform prior to and after alarm.
5. If alarm recording is on, the recorder starts alarm recording. For further information on alarm recording,
please refer to Chapter Recording.
4.6 When an Alarm occurs
Note
When an alarm occurs, you should always check the patient's condition first.
The alarm message appears at the top of the screen on the right side. It is needed to identify the alarm and
act appropriately, according to the cause of the alarm.
1. Check the patient's condition.
2. Identify the cause of the alarm.
3. Silence the alarm, if necessary.
4. When cause of alarm has been over, check that the alarm is working properly.
You will find the alarm messages for the individual parameter in their appropriate parameter chapters of this
manual.

Freeze
• General
• Freeze & Unfreeze
• Review & Record Frozen Waveforms
5.1 General
When monitoring a patient, you may freeze the waveforms of interest so as to view them carefully. Generally
you can review maximally 34 seconds of a frozen waveform. If required, you may also use recorder to print
out a frozen waveform. The Freeze function of this monitor has following features:
• Freeze status can be activated on any operating screen.
• At the same time of entering the Freeze status, the system exits all other operating menus. Besides,
the system freezes all waveforms in the Waveform area of the Basic Screen, or Full-lead ECG waveforms
and the extra waveform (if available) on the Full-lead ECG screen. Nevertheless the Parameter area
refreshes normally.
• In the Freeze status, it does not affect the display and refresh of the Trend Graph area on the trend
screen, the display and refresh of oxyCRG on the Dynamic Refresh screen, or the display and refresh
of the ViewBed window on the ViewBed screen.
• The frozen waveforms can be reviewed or recorded.
5.2 enter/exit Freeze Status
Enter Freeze Status
In the Non-Freeze status, press the "FREEZE" button on the front panel of the monitor to let the system
exit the Menu being currently displayed (if available), then enter the Freeze status and display the popup
"FREEZE" menu. In the Freeze status, except ViewBed waveforms, all other waveforms are frozen. In other
words, the system will no longer refresh all other waveforms.
