Trend Histogram View
Trend Histogram allows users to view up to the last 24 hours of stored data for any selected
record. To select a record, position the cursor to the specific record in Trend Waveform view,
and press the LCD Screens button.
The starting and ending time and date for the selected record are displayed. The Trend
Histogram includes columns with fixed values for SpO
2
and Pulse Rate data. (SpO
2
data
appears in the left column, and Pulse Rate data appears in the right column.)
Figure 5: Trend Histogram
Data summaries are displayed in table format. For example, if the first row of the SpO
2
column
(>95) displays “85%”, this means that 85% of the data collected, the patient’s SpO
2
was greater
than 95. Data summaries may total less than 100% if there are periods in the data collection with
no SpO
2
and Pulse Rate data.
In some instances, data may be identified with a *1, *2, or *3 in the lower right-hand corner of
the LCD display screen. The identifiers are described in the following table.
Nurse Call Feature
The Avant 9700 features a nurse call circuit that can be connected to a facility nurse call system,
allowing alarm conditions to be recognized at a central monitoring location and on the device.
Two switches located on the back of the device under the back cover allow users to activate the
Nurse Call feature.
Option switch 7 allows users to select the duration output of a signal. In the DOWN position, a
one-second signal is output and repeated every 60 seconds when an audible alarm starts and
will continue every 60 seconds until the alarm is silenced. In the UP position, the nurse call signal
is active during the entire duration of an audible alarm.
