to produce a peripheral pulse or the patient may have
poor peripheral perfusion. Also, if a patient’s beat-tobeat
pulse amplitude varies significantly (e.g., because
of pulsus alternans, atrial fibrillation, or the use of a
rapid-cycling artificial ventilator), blood pressure and
pulse rate readings can be erratic, and an alternate
measuring method should be used for confirmation.
General Notes
• A patient’s vital signs may vary dramatically during the
use of cardiovascular agents such as those that raise or
lower blood pressure or those that increase or decrease
heart rate.
9 Because treatment protocols based on the patient’s
blood pressure may rely on specific values and differing
measurement methods, such as auscultatory, clinicians
should note a possible variance from values obtained
with the PRO Monitor in planning patient care
management. The PRO Monitor values are based on
the oscillometric method of noninvasive blood pressure
measurement and correspond to comparisons with
inn-a-aortic values within ANSI /AAMI Standards for
accuracy (a mean difference of + 5 mmHg, and a
standard deviation of + 8 mmHg).
. Several conditions may cause the BP parameter to
calculate and display only the mean arterial pressure
(MAP) without a systolic and diastolic reading. These
conditions include very low systolic and amplitude
fluctuations, so an accurate calculation for these values
can’t be made (e.g., patient in shock); too small of a
difference between systolic and MAP calculations in
relationship to the difference between diastolic and
MAP; or a leak has occurred in the PRO Monitor
(1. Check all BP connections 2. Monitor may need
calibration and leak testing). If only the MAP value is
displayed, the systolic and diastolic will display dashes
(-) and an alarm message “N99-BP FAILED” will be
displayed.
