Automatic Anesthesia Depth Control System For Isoflurane Concentration

The concept of Anesthesia is found from the carvings of about 2500 BC. A few decades back, an anesthesiologist did the anesthesiology, and a patient’s life depended on one person. So, there was a dire need to automate this system to achieve precision and accuracy and lessen the load from the shoulders of an anesthesiologist. Feedback Control is found everywhere in Engineering World and has shaken up the protection in the fields from Car travel to space. This article discusses the History, Design, and Working of an automatic anesthesia delivery system. It further includes the modern-day investigations in the field, i.e., closed-loop anesthesia Delivery Systems and Target controlled infusion. The introduction of the Bispectral Index as a significant indicator of Depth of Anesthesia is also a part of this article. The supply of low/high doses of anesthesia during an operation may cause adverse effects to the patient. To avoid this situation, an Automatic Anesthesia control system is required to control the amount of anesthetic provided, reducing human error and high precision. The Concentration of the drug is controlled by a multi-task feedback system and Microcontroller chips. Closed-loop systems can make conclusions on their manner. Our work further discusses the superiority of closed-loop systems over the open-loop system and their advantages and disadvantages. The significance of this work is that it helps anesthesiologists to enter a targeted value in the system of human body and save precious lives. The approach will have software-based simulations and empirical data to reduce tolerance levels. The difference in practice will be that we will consider the problems in this automatic control system and try to remove pests with effective use of controls engineering knowledge. The purpose is to make an automated anesthesia control system for isoflurane concentration with a high level of accuracy. Multitasking is the main characteristic of an automatic anesthesia machine, and we will try to discover ways to make it cost-effective, compact, and easy to use. It will be easy to use with a User-Friendly Graphical User Interface and equipped with the latest technology based on researches from the last decade.
