Make sure that you are using a Philips-approved correct sized cuff, and that the bladder inside the
3
cover is not folded or twisted.
A wrong cuff size, and a folded or twisted bladder, can cause inaccurate measurements. The width
of the cuff should be in the range from 37% to 47% of the limb circumference. The inflatable part
of the cuff should be long enough to encircle at least 80% of the limb.
4
Apply the cuff to a limb at the same level as the heart. If it is not, you must use the measurement
correction formula to correct the measurement.
The marking on the cuff must match the artery location. Do not wrap the cuff too tightly around
the limb. It may cause discoloration, and ischemia of the extremities.
WARNING
Inspect the application site regularly to ensure skin quality and inspect the extremity of the cuffed
limb for normal color, warmth, and sensitivity. If the skin quality changes, or if the extremity
circulation is being affected, move the cuff to another site, or stop the blood pressure
measurements immediately. Check more frequently when making automatic measurements.
Correcting the Measurement if Limb is not at Heart Level
To correct the measurement if the limb is not at heart level, to the displayed value:
Add 0.75 mmHg (0.10 kPa) for each centimeter
higher or
Add 1.9 mmHg (0.25 kPa) for each inch higher.
Recommendations For Measurements Used in Diagnosis of
Hypertension
To make a measurement for use in the diagnosis of hypertension, follow the steps below:
Ensure the patient is comfortably seated, with their legs uncrossed, feet flat on the floor, and back
1
and arm supported.
2
Ask the patient to relax and not talk before and during the measurement.
If possible, wait 5 minutes before making the first measurement.
