Chapter 8 Freeze
8.1 General
When monitoring a patient, you may freeze the waveforms of interest so as to view them
carefully. Generally you can review a frozen waveform of a maximum of 12 minutes. The Freeze
function of this monitor has the following features:
Freeze status can be activated on any operating screen;
Once 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, and also freezes
Full Lead ECG waveforms and extra waveforms on the Full Lead ECG interface (if any).
Nevertheless the Parameter area refreshes normally.
The frozen waveforms can be reviewed and recorded.
8.2 Entering/Exiting Freeze Status
Enter Freeze Status
In the Non-Freeze status, press the FREEZE button on the control 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 FROZEN menu. In the Freeze status, 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 in/from the FROZEN menu;
Press the FREEZE button on the control panel again;
Press the non-immediate-to-execute button (for example, once a button is pressed, a menu
will pop up for you to further select an option) on the front panel and system buttons of
Menu and Main;
Execute any operation that may trigger the adjustment of the screen or the display of a new
menu.
After exiting the Freeze status, the system will discharge the Freeze status, clear screen
waveforms and resume display real-time waveforms. In the Screen Refresh mode, the system will
sweep the waveforms from left to right in the Waveform Area.
