Abstract: AN Obstructive Sleep Apnea (OSA) is a serious health disorder which contributes to cardiovascular complications, decreased work productivity, automobile accidents, and death. This condition is characterized by a temporary and repetitious cessation of breathing resulting from repeated upper airway closure during a person’s sleep. OSA is classified by several different components. Apneas, Hypopneas and blood oxygen saturation (spo2) are the main constituents of this disorder. An apneic episode is a complete cessation of airflow lasting 10 sec or more, while a hypopnea is a reduction in respiratory airflow combined with a spo2 decrease of >4%. Additional factors, which the sleep specialist feels are clinically significant, may also be accounted for and included when diagnosing OSA. The instrument used in diagnosing OSA usually require the patient to undergo a sleep study called a polysomnogram (PSG). This overnight study consists of monitoring brain electrophysiological responses, heart rate and rhythms, respiration, blood oxygen levels, and leg movements. Electrodes are attached to the patient’s skin and monitored by a sleep technician throughout the test. Data from this test is used to diagnose OSA, grade its severity and help determine optimal therapeutic approaches. So OSA has acquired an severe problem associated with pulmonary circulation. Normally the PSG test is carried out in clinics and hospital associated with sleep technician due to this patient’s sleep gets disturbed in hospital environment within the same time . Therefore, the goal of this project is to design a portable, lightweight and low-cost sleep monitoring system to detect apnea for people with a snoring problem using flow sensor and spo2 we are going to detect OSA, Hypopneas and central sleep apnea and display the Indexes in the display as an real time monitoring. The Proposed system will help the doctors in early detection for OSA which will be more efficient to titrate with an PAP devices such as CPAP (continuous positive airway pressure) and with BPAP (bidirectional positive airway pressure). So due to our proposed system an lower grade peoples also gets diagnosed earlier with minimal cost.
