MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641025931 A) filed by Sri Sai Ram Engineering College, Chennai, Tamil Nadu, on March 5, for 'detection of sleep apnea.'
Inventor(s) include Aakashp. S; Bhuvanesh Kumar U; Yuwan Sooriya K. G; and Nazeeya Anjum N.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a non-invasive sleep apnea detection system designed to monitor breathing patterns during sleep using acoustic signal analysis. The system employs a sensitive microphone to capture respiratory sounds throughout the night. The recorded signals are processed using noise filtering and Fast Fourier Transform (FFT) techniques to generate spectrograms for detailed breathing pattern analysis. Apnea events are detected by identifying prolonged breathing pauses and abnormal respiratory cycles. The system further classifies the condition into obstructive sleep apnea, central sleep apnea, or mixed sleep apnea based on breathing characteristics. Severity is determined using the Apnea-Hypopnea Index (AHI), which measures the number of apnea events per hour of sleep. The results, including spectrogram visualization, apnea classification, and severity level, are displayed on a connected device. The invention provides a portable, cost-effective, and user-friendly alternative to conventional sleep laboratory diagnostics, enabling early detection and improved management of sleep apnea."
