Directions for use
Note
NIBP measurement
The monitor enables you to take manual and automatic NIBP measurements.
At the start of a measurement, the monitor inflates the cuff to the appropriate level. In the NIBP
frame, the systolic display shows the cuff inflation pressure while the blood pressure measurement
is in progress.
The monitor measures blood pressure as the cuff is inflating. If patient movement, excessive noise,
or an arrhythmia prevent the monitor from determining the blood pressure while the cuff is
inflating, the monitor attempts to measure the blood pressure while deflating the cuff.
When the measurement is complete, the NIBP frame displays the measurement until you save it to
the patient's record or you start another NIBP measurement.

Note
In situations where you cannot position the cuff level with the heart,
you should adjust the measurements as follows for greater
accuracy. For each inch (2.54 cm) that the cuff is above the level of
the heart, add 1.8 mmHg to the displayed reading. For each inch
(2.54 cm) that the cuff is below the level of the heart, subtract 1.8
mmHg from the displayed reading. It is important to document the
adjustment on the patient record.
WARNING NIBP readings may be inaccurate for patients experiencing moderate
to severe arrhythmia.
WARNING Do not allow a blood pressure cuff to remain on neonatal patients
more than 90 seconds when inflated above 5 mmHg. Do not allow a blood pressure
cuff to remain on the adult patients more than 3 minutes when inflated above 15
mmHg. Excessive cuff tightness may cause venous congestion, peripheral nerve
injury, discoloration of the limb, and patient distress.
WARNING Inaccurate measurement risk. Pulse rate measurements generated
through the blood pressure cuff or through SpO2 are subject to artifact and might
not be as accurate as heart rate measurements generated through ECG or through
manual palpation.
WARNING Use caution when measuring blood pressure using oscillometric
blood pressure devices in severely ill neonates and pre-term infants because these
devices tend to measure high in this patient population.
Caution Inaccurate measurement risk. Any external compression of the blood
pressure hose or cuff may cause system errors or inaccurate measurements.
The Pediatric and Adult blood pressure modes are supported on patients 29 days
and older. The Pediatric mode gives you the option of setting a lower initial inflation
pressure when using the StepBP deflation and not SureBP.
Use dual-lumen tubes for adult and pediatric blood pressure measurements and
single-lumen tubes for neonate blood pressure measurements. Mismatching tube
types, patient types, and algorithms causes an information message to appear in
the Device Status area. For neonate patients, set the NIBP settings as follows:
Patient = Neonate, Tube type = 1 tube, Algorithm = Step.
Welch Allyn uses the following definition of Neonate: Children 28 days or less of age
if born at term (37 gestation or more); otherwise, up to 44 gestational weeks.
