WARNING
Never use an adult or pediatric monitor setting or cuff for an
NIBP measurement on a neonatal patient. Adult and pediatric inflation
limits can be excessive for neonatal patients, even if a neonatal cuff is
used. Neonates are defined in the AAMI SP10:2002 standard as children 28
days or less of age if born at term (37 weeks gestation or more); otherwise,
up to 44 gestational weeks.
CAUTION Correct sizing of the blood pressure cuff is important for
accurate blood pressure readings. A cuff that is too small might provide
false high readings, while a cuff that is too large might provide false low
readings.
The monitor uses the oscillometric method to determine blood pressure; therefore, if the
cuff extends to the antecubital fossa (bend in the elbow), you can still acquire an
accurate blood pressure reading.
Before taking an NIBP measurement, follow these steps to select the appropriate cuff
for the patient.
1. Measure the circumference of the patient's bare upper arm, midway between the
elbow and shoulder.
2. Choose the appropriate cuff size based on the circumference measurement. If the
circumference of the patient's arm falls between two cuff sizes, use the larger cuff
size.
3. Wrap the cuff around the patient's bare upper arm and verify that the artery index
marker lies somewhere between the two range markings on the cuff.
