WARNING! Do not use the NIBP option without proper training. Setting initial inflation pressure
too high can result in serious injury to the patient. Patient movement, very low pulse
volume, or vibration from outside sources can influence the accuracy of blood pressure
measurements.
How Does the NIBP Option Work?
The patient blood pressure cuff and hose connect to the R Series unit through the NIBP
connector on the rear panel of the unit. The NIBP button (
) on the front panel of the
R Series allows you to initiate and terminate non-invasive blood pressure measurements, whose
values display in the NIBP area of the monitor. You can also initiate and terminate Auto or
STAT mode measurements using the softkeys on the NIBP menu.
The ZOLL R Series NlBP Option non-invasively measures arterial blood pressure and pulse
rate in resting adult, neonate and pediatric patients. By incorporating the SunTech Medical
Advantage OEM BP A+ R-wave Motion Tolerance Module into the R Series
Defibrillator/Monitor/Pacemaker devices, the option facilitates the ability to monitor and assess
the physiological characteristics of the indicated patient populations.
The NIBP module measures the oscillometric pulses transmitted through the blood pressure
cuff and hose, and calculates the blood pressure measurements accordingly. The pressure
measurement cycle takes approximately 30 seconds and proceeds as follows:
1. The cuff inflates to a preconfigured pressure (configured default value for adult patients is
160 mmHg), above the patient’s systolic blood pressure, to occlude blood flow through the
arteries in the monitored limb.
2. The cuff deflates incrementally, allowing blood to flow through the cuff and into the
monitored limb.
3. As blood flows past the partially deflated cuff, it produces pressure oscillations that are
transmitted to the R Series unit through the hose.
4. The R Series unit measures the oscillometric pulses and uses them to calculate the
corresponding systolic, diastolic, and mean blood pressure, as well as the patient’s pulse rate.
5. The NIBP option automatically adjusts the blood pressure measurement procedure in
response to certain error conditions such as:
Condition Adjustment/Response
The unit cannot detect
systolic pressure The unit automatically
increases the cuff inflation
pressure and completes
the blood pressure
measurement
The unit cannot detect
systolic, diastolic or
mean pressure after
3 minutes The unit aborts the blood
pressure measurement
and deflates the cuff
The unit detects a
fault The unit displays a
corresponding error
message on the monitor
and aborts the
measurement
