Ventilator Using Arduino with Blood Oxygen Sensor

The human lungs use the again stress generated through the contractile motion of the diaphragm to inhale and breathe air. The ventilator uses reverse motion to inflate the lungs with pump motion. The ventilation mechanism should be able to provide 1030 breaths per minute and accommodate two sets of increments. The Ventilator ought to additionally be capable of alter the quantity of air this is driven into the lungs with every breath. Last but not least, so far it has been set to adjust the duration of the inhalation-exhalation ratio. In either case, the ventilator should be able to monitor the patient's blood oxygen levels and exhaled lung pressure while avoiding gauge / high pressure. Designed and developed using Arduino here, the ventilator meets all of these requirements, creating a reliable and affordable ventilator to help during a pandemic. Here, the ventilator bag driven by a stepper motor. Our system uses a blood oxygen sensor along with a heart rate sensor (KY039) and a temperature sensor (18B20) to monitor the patient's required vital signs and display them on a mini LCD screen. The uses of air purifier to purify the air, as normal ambient air affects the patient. Whenever a patient faces a dangerous position, a buzzer sounds to notify a nearby caretaker. The buzzer is attached to the Arduino with a relay to boom the voltage. Patient records is uploaded to the cloud through an IOT modem. The whole machine is managed with the aid of using the Arduino controller to get the preferred result.
