Design of an embedded PID controller applied to blood pressure control

Some diseases, such as hypertension, require a close control of the patient´s blood pressure. This is even more critical when that patient is going through — or has just underwent — a surgical procedure In such situations, reducing blood pressure to normal levels is of paramount importance. Usually, this demanding and time consuming monitoring is done manually by clinical personnel and are subject to mistakes and inconsistent practices. In this paper, we propose a solution to the manual monitoring through the design and implementation of an embedded PID controller to handle blood pressure, integrated to an automated monitoring system to assist in detecting anomalies and to optimize the process of patient care.
