Note: It is recommended that the clinician ask the patient to relax and not speak during
measurement.
Note: It is recommended that 5 minutes elapse before the first reading is taken.
Cuff Selection and Placement
Rad-97 uses a bayonet hose with a blood pressure cuff to measure NIBP. For a list of
compatible NIBP patient hoses and cuffs, visit http://www.masimo.com/.
To ensure the correct cuff size
Wrap the cuff around the arm.
The index line should align within the cuff range markings .
If the index line does not fit within the range markings, select a larger or smaller cuff.
To place cuff on the measurement site
Wrap the cuff around the non-dominant arm, making sure that the Artery Marker is aligned
over the brachial artery as shown in the image below. To locate the brachial artery, place the
pads of your index and middle fingers halfway between the shoulder and elbow, in the middle
of the inner arm, between the bicep and triceps muscles. If possible, do not wrap the cuff over
the patient’s clothing. The cuff should fit snugly around the patient’s arm for maximum
oscillometric signal quality. The lower edge of the cuff should be located 2 cm above the
antecubital fossa (interior bend of the elbow).
Ensure that the air hose from the monitor to the cuff is not compressed, crimped, or damaged.
