Abstract

In a modern operating room, the depth of anesthesia is the responsibility of the anesthetist/anesthesiologist who controls many other vital parameters, such as blood pressure, respiration, heart rate, temperature, blood oxygenation, and exhaled carbon dioxide, within acceptable bounds. Any assistance that the anesthetist/anesthesiologist can obtain automatically will increase safety margins by allowing increased attention to other functions, which not so easily automated. Clearly, patient safety is the ultimate attention of the anesthetist/anesthesiologist. Regarded to this matter, the objective of this project is to design an automated system to regulate the depth of anesthesia. Mean Arterial Pressure (MAP) is regarded as a reliable measure of the depth of anesthesia or in another way, the level of MAP can determine proportionally as guide to the level of inhaled anesthetic of a particular patient. Therefore, the controlled variable will be the measured MAP. As per the objective, MAP will be regulate to any desired set point and maintain the set point in the presence of unwanted disturbances. The closed-loop system will respond rapidly and smoothly to changes in the MAP set point without excessive overshoot. It will also minimize the effect of unwanted disturbances, such as, surgical disturbances due to skin incisions and measurement noise. Finally, the system must be applicable to many different patients. Control specifications of this system will be based on clinical experience of the patient such as settling time and percent overshoot.
