NIBP: Principles of SuperSTAT Noninvasive Blood Pressure Determination
11-20
NOTE: (Adult/Pediatric only) When ECG is monitored, SuperSTAT NIBP is able to
determine blood pressure in the presence of irregular heart rhythms. At
the beginning of a SuperSTAT NIBP determination, the coefficient of
variation from the previous 120 ECG R-R intervals is used to determine if
an irregular rhythm is present.
Accuracy of the NIBP parameter was validated against the intra-arterial
method. Do not use the auscultatory method to verify the accuracy of the NIBP
parameter. Auscultatory method (using cuff and stethoscope) calculates the
mean pressure value from audible sounds at systolic and diastolic, but the NIBP
parameter method detects all three values.
WARNING
Arrhythmias will increase the time required by the NIBP
parameter to determine a blood pressure.
