An overly loose fitting cuff may lead to inaccurate blood pressure values. Therefore, an appropriate cuff fit is very important to obtain an accurate blood pressure measurement.

Microlife Cuff Fit Check technology evaluates the signal during cuff inflation of a measurement, to determine if the cuff fit is sufficiently tight or not, and then displays corresponding symbols to indicate the cuff fit status. Please note that Cuff Fit status will be displayed only after the cuff is inflated to pressure above the user's diastolic pressure, because it takes time to check the pulse signal.

• If the cuff fit tightness is appropriate:
  • A Cuff Fit symbol with a check mark is displayed to indicate good cuff fit. 
  • Because cuff fit is good, please continue with the measurement.
• If the cuff fit tightness is less than optimal:
  • A Cuff Fit symbol without a check mark is displayed to indicate sub-optimal cuff fit.
  • Because cuff fit is sub-optimal, it is recommended to stop the measurement. Remove extra clothing on the measurement arm and re-apply the cuff more snugly, then retake measurement.

Microlife Cuff Fit Check technology indicates the cuff fit status to the user during cuff inflation, so users can interrupt the measurement and adjust the cuff tightness in the case of a sub-optimal cuff fit. Microlife Cuff Fit Check ensures that the blood pressure measurement is conducted reliably with an optimal cuff fit and helps to avoid potential deviations from a loosely fitted cuff.

Moreover, the average of blood pressure values stored in the measurement memory of a blood pressure monitor is computed based only on measurement entries with the Cuff Fit Check status being optimal. Therefore, measurements with sub-optimal Cuff Fit are not used for the computation of the blood pressure average.

Microlife Cuff Fit Check technology is a standard feature on the 4^th generation Microlife blood pressure monitors.
