Directions for use
Select a cuff
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.

WARNING Use only blood pressure cuffs and hoses listed as approved
accessories to ensure safe and accurate NIBP measurements.
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.
