1. IEEE PROJECT BIOMEDICAL APPLICATION-
Automatic Anesthesia Controller using Heart Beat
Sensor
At the present time anesthetics, drugs which
induce loss of awareness, are often used for surgical
operations. A general anesthetic should cause a
progressive depression of the central nervous system
and cause the patient to lose consciousness. In
contrast, a local anesthetic will affect sensation at the
region to which it is applied.

2. To maintain an adequate depth of anesthesia
without compromising patient's health, an
anesthesiologist usually works as a multi-task
feedback controller to roughly regulate the drugs
titration while observing a variety of patient outcomes.
Automatic anesthesia controller design aims to
automatically regulate anesthesia levels by taking
account on several physiological measurements and
then frees up anesthesiologists for more important
tasks in operation.
This project designed using the PIC
Microcontroller aids in the control of feeding
Anesthesia for patients during Surgery times. This
project Consists of a Heart Beat sensor to detect the
Heart beat rate and a Mechanical Arrangement with
syringe for feeding anesthesia to the patients.
Operation:
First the Syringe is filled with anesthesia
liquid and kept in the mechanical arrangement. And
the Heart beat rate is calculated. Then the Liquid is

3. slowly injected into patients body and the changes in
the Heartbeat rate is observed. Then according to the
Heart beat rate the Liquid is injected into the body.
The injecting process is controlled by the
movement of the Stepper Motor.
The Complete Status is Indicated in LCD with
online Updations.
