Vital Signs Monitor 27
You may find that the bottom of the cuff extends to the antecubital fossa (bend in the elbow) on
many people, but because the Monitor uses oscillometric technology, not auscultation, this will
NOT result in an inaccurate blood pressure.
Careful sizing of the cuff is important to the accuracy of blood pressure readings. If the cuff is too
small, the readings could be falsely high.
There are two simple methods for determining the correct cuff size for the patient. Use either
method (A) or (B) below.
A. Determining Cuff Size with the Cuff Markings
One way to ensure proper cuff size is to wrap the cuff around the patient's upper arm and visu-
ally check it. The cuff is marked with a distinct white edge and two divisions that indicate
"range." When the cuff is properly fit, the edge will meet the cuff at some point within the range.
B. Chart for Determining Cuff Size
You can also determine cuff size by measuring the patient's arm circumference midway between
the elbow and shoulder, and then use the chart below to select the correct cuff.
The Welch Allyn Vital Signs Monitor is not intended to be used on Neonatal patients. To
ensure pediatric blood pressure accuracy and safety, note that the Welch Allyn Small Child cuffs are
the SMALLEST CUFFS approved for use with young children and infants. The circumference of the
child’s arm must fit within the range markings on the cuff.
CAUTION: When measuring blood pressure on children younger than age 3 it is recommended
that the Pressure Preset (initial inflation pressure) be set at 160 mmHg or lower.
Positioning the Blood Pressure Cuff
The preferred blood pressure measurement site for adults and children is the upper arm. The arm
must be relaxed and motion-free during measurement(s).
WARNING: Do not place the cuff on any extremity being used for intravenous infusions, or any area where
circulation is or may be compromised.
