Design and development of continuous positive airway pressure machine for snoring

Continuous Positive Airway Pressure (CPAP) is used to maintain the most effective way to live with obstructive sleep apnea. The working principle of the machine is to blow air through the nose or mouth to keep open the upper airway all the time. The price of CPAP in the market is very expensive which affects many people who need to use CPAP for treatment but cannot afford it. The design and development of a prototype CPAP which functions in the way it is supposed to will be the main objectives of this study. The results of a performance test show that accuracy of the measurement of moisture is 94.09% and the accuracy of temperature measurement is 99.20%. The pressure sensor has an accuracy of over 97%. The CPAP machine provided similar pressure to the ideal pressure values for CPAP settings. The results are quite satisfactory which can be a platform for future study of clinical trials.
