Design a medical device to monitor the human body (blood oxygen saturation, heart rate, body temperature)

The normal range for blood oxygen saturation is 80–100%. As a result, the body’s blood oxygen levels must be maintained. Humans are also essential to keep their cardiac condition in good working order. Because the heart is a vital organ in the human body, its disease is the leading cause of death. As a result, the heart’s state must be checked, one of which is the condition of a normal pulse range from 60 to 100 beats per minute. Monitoring human body temperature is just as critical as monitoring oxygen saturation and heart rate, especially in young children. Science and technological advancements must be able to assist in the resolution of human medical difficulties. challenges that threaten human survival, an integrated assessment of oxygen saturation in the lungs was used in this investigation. The human body’s blood, heart rate, and temperature have been combined into a single tool, with measurement results shown immediately on the measuring instrument’s LCD display. The MAX30100 sensor detects blood oxygen saturation and heart rate, while the MLX90614 sensor detects body temperature. All of the sensors are linked to the Arduino. Temperature, oxygen saturation, and heart rate are all measured by the unique sensors. The code for each sensor is written using the Arduino software. Following that, the entire set of results is presented on the LCD panel. One of the advantages of the device used is that it is light in weight and can be carried anywhere and easily, accurate reading, takes more than one reading at a time (it is possible to measure the temperature and the percentage of oxygen saturation at the same time), and low cost, unlike the devices used in the medical field. Another feature of this device is the use of the keyboard. This panel is used in the project for security and to lock the equipment so that only the operator and responsible engineer can use it. Three tables have been created to compare the sensors used in the paper with standard medical equipment used in hospitals. The result is reached. The sensors have been tested on ten different age groups, including adults, teens, and children, and have been proven to be highly accurate and reliable, allowing the doctor to get readings and detect problems.
