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.
Exit Freeze Status
In the Freeze status, executing any of the following operations will command the system to exit the Freeze status:
Select the “EXIT” option on the “FREEZE” menu;
Press the “FREEZE” button on the front panel again;
Press the non-immediate-to-execute button (such as a button once pressed, a menu will pop up for you to further
select an option )on the front panel and system buttons of MAIN and MENU;
Execute any operation that may trigger the adjustment of the screen or display of a new menu.
After exiting the Freeze status, the system will discharge the Freeze status, clear screen waveforms and resume to
display real-time waveforms.
5.3 FREEZE Menu
Press the “FREEZE” button on the panel, the FREEZE menu will appear on the bottom part of the screen. At the same
time, the system enters the Freeze status.
Figure 5-1 FREEZE Menu
WAVE 1: used to select the first frozen waveform to record. The pull-down list of this item gives you the names
of all frozen waveforms displayed on the screen.
WAVE 2: used to select the second frozen waveform to record. The pull-down list of this item gives you the
names of all waveforms displayed on the screen.
RECALL: used to review frozen waveforms.
REC: after selected, the system begins recording the frozen waveforms selected in "WAVE 1" and "WAVE 2".
EXIT: after pressed, the system closes the FREEZE menu and exits the Freeze status.
Note
Pressing the “FREEZE” button repeatedly in a short time may result in discontinuous waveforms on the
screen.
5.4 Reviewing Frozen Waveform
By moving the waveform, you may review a waveform of 34 seconds before the moment when it is frozen. For a
