Background: One of the most prevalent methods in noninvasive blood pressure (BP) measurement
with cuff is oscillometric, which has two different types of deflation, including linear and step deflation.
With this approach, in addition to designing a novel algorithm by the step deflation method, a sample
of its module was constructed and validated during clinical tests in different hospitals. Method: In this
study, by controlling the valve, the pressure would be deflated through optimized steps. By real‑time
processing on the obtained signal from the pressure sensor, pulses in each step would be extracted.
After that, in offline mode, mean arterial pressure is estimated based on curve fitting. Result: A BP
simulator, various modules, and an auditory method were used to validate the algorithm and its results.
During clinical tests, ۸۰ people (men and women), ۱۱ dialysis patients, and ۶۹ non-dialysis (healthy
or with other diseases) in the age range of ۱۷–۸۵ years participated. Conclusion: The obtained results
compared with the BP simulator are in the standard range according to the international medical
standards of the British Hypertension Society (BHS) and the US Association for the Advancement of
Medical Instrumentation (AAMI), which are the global standard of comparison in this field.
