Why Use Simulators?

Summary

Revision C
Appropriate Use of NIBP Simulators: Appropriate Use of NIBP Simulators
"Neither the monitor or the BP Pump 2 is broken. Some monitors were designed
to give readings close to those obtained by the Auscultatory method of blood
pressure determinations. Other monitors have been designed to agree with
Invasive blood pressure readings. It is well known that Invasive and Auscultatory
BP readings on the same subject can be quite different" (6)
Both of these statements indicate that these simulators cannot be used to
demonstrate the accuracy of an NIBP monitor.
Simulators provide a method for producing repeatable signals that can be used
to check that the monitor is responding to noninvasive blood pressure signals.
Reference values obtained from a particular make and model of an NIBP
monitor can be used to confirm that no changes have occurred after service to
that same type of monitor.
Simulators can also be used to test for leaks and conduct static pressure
calibration of NIBP monitors and as part of preventive maintenance programs.
The accuracy of an NIBP monitor can only be determined by comparison to a
clinical blood pressure reference. NIBP simulators are useful for certain types of
testing, but should not be used for accuracy testing.
