14. Abnormal Phenomena and Handling
Q3: When can I obtain better measurements?
● The cuff is not tight enough. If the cuff is loose, the
compression force might fail to transmit to the artery, causing
the blood pressure value to be much higher than it is.
Therefore, re-adjust and tighten the cuff further.
● The patient is not sitting correctly during measurement.
Slouching, tilting, bending, and sitting cross-legged are not
encouraged while taking blood pressure measurements due
to increased abdominal pressure or the arm position being
below the heart. Kindly take readings in the correct posture.
● Measurements are best taken in the mornings right after
you urinate or when your mind and body are stable. We
recommend taking readings at the same time of the day,
every time.
If the measurement is abnormal, any of the following symbols
may appear. Kindly use the recommended method for
measurement.
