SYSTOLIC AND DIASTOLIC SHIFT – The NIBP-1000 Series is equipped with the option
to shift test results to compensate for different methods of measuring Oscillometric NIBP
by various manufacturers and models of devices under test.
There are no absolute standards for Oscillometric NIBP readings; therefore, for a number
of reasons (including patents, technology, etc.), each manufacturer has established a
different method for evaluating the oscillometric pulses. Due to these varying methods,
precisely the same waveforms will give different results on different manufacturer’s units.
The normal technique used is to run the monitor against a fixed source like the NIBP-1000,
with the understanding that each manufacturer has a predictable error from this norm.
While this is generally the most direct method, users have asked for a method to correct
for this difference, making the monitors read the same as the test unit. The Systolic and
Diastolic Shift settings allow for just such correction.
These adjustments are indicated in a line added to the main display to inform the user of
any shift that has been programmed into the system. This is done so there is no
misunderstanding of the meaning of the results.
CAUTION
These adjustments must be used with caution as they will
allow the user to adjust the output results to invalid values.
These adjustments should only be used to aid in the
simplification of testing and with documented controls.
