Chapter 23 Freeze
When monitoring a patient, the user may freeze the waveforms and examine them. Generally, the
user 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.
23.1 Entering/Exiting Freeze Status
23.1.1 Entering Freeze Status
In the Non-Freeze status, press the button on the control panel of the monitor or select the
shortcut key
to exit the current menu. Press the button or select the shortcut key

By moving the frozen waveform, you may review a waveform of 12 minutes before it is frozen.
For a waveform of less than 12 minutes, the remaining part is displayed as a straight line. Select
Time on the Freeze menu and use the up/down arrow keys to move the frozen waves so that you
can review the other parts of the frozen waves not displayed on the current screen.
