Blood Pressure Operation
Blood Pressure Cuff Selection
Careful sizing of the cuff is important for accurate blood pressure readings. If the cuff is
too small or too large, you may have false high or low readings, respectively. When there
is an area of overlap for using a smaller or larger cuff, use the larger size cuff.
The device uses oscillometric technology; therefore, if the cuff extends to the antecubital
fossa (bend in the elbow) this does NOT result in an inaccurate blood pressure reading.
Measure the arm circumference (midway between the elbow and shoulder) for the
correct Reusable Two-Piece Cuff size
(Table 10) or Durable One-Piece Cuff size (Table 11) .
Wrap the cuff around the patient’s upper arm and verify that the artery index marker falls
within the two divisions that identify the “range” on the cuff to indicate a proper fit.
To ensure pediatric blood pressure accuracy and safety, the Child Reusable Two-Piece
Blood Pressure Cuff (4500-01), Infant Durable One-Piece Cuff (REUSE-07-2MQ), and the
