Chapter 15 Freezing
While monitoring a patient, you can freeze the waveform on the screen,
and then you can carefully survey the condition of the patient during this time
interval through reviewing the frozen waveform.
15.1 Freezing Waveform
Under the non-freezing condition, select【Wave Freeze】smartkey on lower
monitor screen or press the button on the front monitor panel, then you
can get the waveform enter freezing condition.
All waveform will be frozen without any more refreshing or roll. The data
displayed in the parameter area will normally be refreshed.
The freezing condition will not influence the following functions:
—— Display and refreshing of dynamic short-time graphic trends.
——Display and refreshing of respiration oxygen chart.
——Display and refreshing of the monitoring screen of other sickbeds.
15.2 Reviewing Waveform
Under the freezing condition, you can browse frozen waveform for careful
survey through the following methods:
Select or , or in the freezing setting, then by turning the trim
knob right or left to make the waveform move right or left accordingly.
Meanwhile, one downward arrow and time scale will be showed at the lower
right corner of each waveform. The initial freezing time is recorded as【0s】.
Select or ,the time interval of the waveform moving is 4s.For
example,when the initial freezing time is recorded as【0s】, select , time
scale will gradually changes into【-4s】,【-8s】,【-12s】… along with the
waveform moving rightwards.
Select or ,the time interval of the waveform moving is 1s.For
example,when the initial freezing time is recorded as【0s】, select , time
scale will gradually changes into【-1s】,【-2s】,【-3s】… along with the
