Numeric Display - Pulse Rate
The Pulse Rate displayed on the Rad-57 may differ slightly from the heart rate displayed on ECG
monitors due to differences in averaging times. There may also be a discrepancy between cardiac
electrical activity and peripheral arterial pulsation. Significant differences may indicate a problem with
the Signal IQ due to physiological changes in the patient or one of the devices or application of the
sensor or patient cable. The pulsations from intra-aortic balloon support can be additive to the pulse
rate displayed on the Pulse CO-Oximeter. Inaccurate measurements may be caused by
