This low cost monitor inflates and deflates the blood pressure cuff in order to determine the mean arterial pressure. In this Instructable, we will explain the set up of the circuity and then explore the coding behind the monitor.īlood pressure monitors are primarily used in clinical settings to analyze patient’s blood pressure and in order to prescribe the best treatment. The circuit design is composed of three basic stages: a low pass filter, a high pass filter, and a noninverting amplifier. It requires the use of a pressure transducer, an Arduino Uno, and coding to control the valve and air pump.
This blood pressure monitor measures the mean arterial pressure (MAP) and approximates the systolic and diastolic pressures.
For our Biomedical Instrumentation course, we created a blood pressure monitor.
