Abstract
A resuscitator is a device that helps patients who are not breathing well to breathe again. It usually works by forcing air or oxygen into their lungs. Bradycardia, as it is known in medical science, is when a person's heartbeat slows down as a result of having breathing difficulties caused by a lung condition. If a person has bradycardia, their heart rate may drop to less than 50 beats per minute, which can be a major issue since it prevents the heart from pumping enough oxygen-rich blood to the body. Patients who require continuous or intermittent ventilatory support can use assisted ventilation with the help of this automatic self-inflating resuscitator. In order to measure the blood flow cycles through our fingertips for this heart rate monitor, IR sensors are employed to detect the blood flow through our fingertips. These sensors can produce pulses in accordance with blood flow when connected to an LM358. LM 358 is a high-gain dual op-amp, and the embedded system built with an 89c52 microprocessor chip receives its output. This controller chip is now set up to detect the heart rate and display it on the LCD. Here, the system is set up to automatically activate the air pumping mechanism when the pulse rate drops to less than 40 because a healthy heartbeat will be more than 60. The pulse rate per minute is shown on an LCD. To start the air-pumping system, a DC motor is utilized.
