ABSTRACT

The human respiratory system relies on the contraction of the diaphragm to create negative pressure, which draws air into the lungs. In contrast, a ventilator uses a pumping action to push air into the lungs. To be effective, a ventilator must be capable of delivering a high volume of breaths per minute, as well as varying the volume of air delivered with each breath. It should also be able to adjust the inhalation-exhalation ratio and monitor the patient's blood oxygen levels and lung pressure. An affordable and reliable ventilator was designed and developed using an Arduino microcontroller, featuring a stepper motor-driven bag, a blood oxygen sensor

and an LCD screen to display vital signs. An air purifier was used to ensure the patient is not exposed to ambient air.

Key words: Aambu bag, Arduino uno, Pulse oximeter.
