Multiparameter Simulator
Simulating Functions
19
Blood Pressure
The Simulator synchronizes dynamic blood pressure
waveforms with all NSR rates and tracks all arrhythmia
selections. Both blood pressure channels (BP-1 and 2)
can be controlled. Each channel can act independently or
can be set together for universal settings.
The Simulator will set the blood pressure channels to a
zero level on power up. This is to allow you to set up the
monitoring equipment under test.
Transducer Sensitivity (All Channels)
Before simulation can begin, blood pressure transducer
sensitivity must be set to correlate with the monitor
manufacturer’s specifications: 40 µV/V/mmHg (code 76)
or 5 µV/V/mmHg (code 77). Simulator accuracy is ± 1%,
± 1 mmHg.
The sensitivity is set through direct code entry by keying
the preset code and pressing ENTER.
Waveform (All Channels)
The Simulator can set a single waveform for all blood
pressure channels. This is set by first selecting 5 =
WAVEFORM. After selecting 5, press ENTER. The LCD
will display BP CHANNELS SET. The waveforms will
appear only during ECG waveforms where blood
pressure waveforms occur (e.g., during the asystole
selection, all pressure channels drop to 0 level).
Blood Pressure Artifact (All Channels)
You can insert a respiratory artifact, as required, into any
waveform over all channels. Insert artifacts by keying 84,
then pressing ENTER. Stop insertion by keying 85, and
then pressing ENTER.
BP Static Levels (All Channels)
The blood pressure static level can be set through direct
code entry, as below, or selected and adjusted through
first selecting 4 = STATIC. After selecting 4, press
ENTER, and then use the CHANGE keys
to scroll to
the available presets.
BP Static Levels, Channels 1 and 2
BP Static Levels, Channels 1 and 2 can be set through
direct code entry, as below, or selected and adjusted
through first selecting 94 = P1,2 STAT. After selecting 94,
press ENTER, and then use the CHANGE keys to
scroll to the available presets. Note that this will affect all
pressure channels, and the Simulator will not display the
levels for BP channels 1 and 2.
