Abstract

The Obstructive Sleep Apnea (OSA) is a disorder that causes frequent pauses in breathing during sleep. This disorder can cause early death, hypertension, etc. Approximately the 4% of the population suffers this disorder. In order to diagnose, it is required a polysomnography (PSG) which s is an expensive test and requires the patient’s hospitalization for at least one night This paper presents a system able to detect the OSA during sleep. Our system consists of a sound sensor, a vibrating element and a microcontroller to process the collected data. The sound sensor is placed in the pillow and includes a vibrating element that wakes the user when the OSA event is too long. The sensor and actuator are connected to a microcontroller which includes an IEEE 802.11 interface to be connected to an Access Point (AP). The collected values are processed and sent to a database. The system works analyzing the sound of snoring. Our system can difference 5 different types of snoring: (I) no snoring, (II) movement (III) normal snoring, (IV) snoring before OSA, and (V) OSA. After that, the values of OSA events are checked by the doctor to take, if needed, the appropriate actions. The results show that we can differentiate the different snoring types thanks to the sound level and the distribution curve. Finally, the system has been verified with a patient with OSA diagnosis and our results coincide with the type of diagnosis and type of snoring that the patient received in his medical report.
