Blood pressure monitors help make precise diagnoses of patients who suffer from hypertension by implementing techniques such as oscillometric methods and Korotkoff's measurements.
They measure mean arterial pressure (MAP) and use algorithms to derive systolic and diastolic values.
Blood pressure monitors display readings on an LCD screen and are driven by a low-power, 8-bit or 32-bit MCU and incorporate a pressure sensor in either an arm or wrist cuff.
