CareFusion PulseTrace PCA2 Manual Operativo página 10

If the 'Spot Check' icon is selected then
an information help screen is displayed
showing the correct patient/arm position
that should be used if the recommended
test procedure is being followed, page
20.
Click OK to start test.
The Spot Check Test screen will be
displayed. The lower display area shows
the real time pulse volume waveform.
The signal displayed might be small at
first but will gradually increase to fill the
lower screen area. It normally takes 60s
for the waveform to stabilise and during
this period the PulseTrace is estimating
the baseline pulse interval and its
standard deviation. Once this has been
established, the display will change and
you can start a spot measurement.
Confirm that you are satisfied with the
waveform, and press the 'Start' button.
It will then collect and average a
minimum of 6 pulse waveforms (user
defined) with a pulse interval close to the
average pulse interval. 'Close' is defined
from the standard deviation.
