Respiratory diseases like – Chronic Obstructive Pulmonary Disease (COPD) and sleep apnea represent significant challenges in respiratory health, often necessitating advanced therapeutic interventions. Bi-level Positive Airway Pressure (BiPAP) therapy has emerged as a pivotal treatment modality for patients afflicted with these conditions, offering tailored airway pressure support to alleviate symptoms and improve respiratory function during sleep. However, traditional ventilators can be expensive, making them less accessible for patients in need. Our project presents a novel approach to BiPAP therapy through the design and implementation of a device utilizing an AC air blower controlled by a TRIAC for precise pressure regulation during both inhalation and exhalation phases. During inhalation, the device provides a high flow rate ensuring sufficient air supply to the patient’s airways for comfortable breathing. In contrast, during exhalation, the device automatically adjusts the flow rate accompanied by a reduced pressure of facilitating gentle expulsion of air from the lungs without imposing excessive pressure on the airways. This innovative approach not only addresses the specific respiratory requirements of COPD patients but also caters to individuals suffering from sleep apnea, where disrupted breathing patterns during sleep pose significant health risks. By offering customizable pressure support, this device aids in maintaining airway patency and alleviating breathing disturbances, thereby improving sleep quality and overall respiratory health. It provides a cost-effective and efficient solution for pressure regulation in BiPAP therapy, enhancing accessibility in resource-constrained environments. The improvement and success of this low-cost, portable BiPAP device has the potential to revolutionize the way respiratory support is provided, making it more affordable and accessible for patients worldwide.
