Blood pressure hose and cuff
Identify and have available the ProBP 3400, blood pressure cuff, and the blood pressure hose.
1. Inspect the blood pressure hose; notice that one end has a single, gray Welch Allyn FlexiPort
fitting and the other end is plain with two recessed holes.
2. Completely push the plain end of the blood pressure hose onto the two silver blood pressure
ports on the device. Make sure the hose is fully seated.
3. Snap the Welch Allyn FlexiPort connector onto the blood pressure cuff.
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 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.
Measure the arm circumference (midway between the elbow and shoulder) for the correct cuff
size.
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.
The following table provides measurements for Welch Allyn blood pressure cuffs.
