vPad-A1 OPERATORS MANUAL
Referring to
Figure 27
, the middle of the screen provides a group of common
ECG
parameters that can be
modified. Some waveforms may not allow a certain parameter to be changed, in which case the parameter's
button is shown in grey and is disabled.
Figure 29
shows the common parameters display when all buttons
are enabled. When parameter buttons are enabled, users can change
the setting as detailed in section
4.1.3 - Parameter Values and
Options
.
• The
Amplitude
parameter sets the size (in millivolts [ mV ])
of the
ECG Waveform
.
• The
Rate
parameter sets the repetition frequency (in Beats
per Minute [ BPM ]) of individual pulses. It may be
adjustable or fixed, depending on the
ECG Waveform
in use.
• The
Artifact
parameter selects a simulated noise that is superimposed on the
ECG Waveform
, if
applicable.
• The
Mode
parameter selects an
ECG Waveform
sub-type, if applicable.
Note
: When simulation of
Intra-Uterine Pressure
(IUP, section 4.5.2.3 ) is active, the IUP simulation
overrides the
ECG
settings of Figure 29 to output a special
Fetal ECG
waveform. Attempts to
change any
ECG
settings via the menu of
Figure 29
will have no effect until a different
Invasive Blood Pressure
simulation (
Static
or
Dynamic Blood Pressure
) is selected.
4.2.3 Normal Sinus Rhythm (NSR)
Normal Sinus Rhythm
(
NSR
) is a basic
ECG
simulation that tests a patient
monitor's ability to correctly display and/or measure signals as produced by
a normally-functioning heart. This simulation has a range of heart
Rates
and signal
Amplitudes
, two simulation
Modes
(Adult or Neonatal), as well
as several different
Artifacts
.
Besides the common
ECG
parameters,
NSR
also has an
Axis
setting that
simulates different physical orientations of the heart relative to the positions
of ECG chest leads. Touching the second dropdown list will display the
available selections. Select a list item to set the
NSR Axis
.
