A polysomnography (PSG) system is an advanced sleep study setup used to monitor a patient overnight while they sleep. It simultaneously records multiple physiological parameters, including brain waves, breathing patterns, oxygen saturation, heart rate, and body movements. By capturing these detailed data points, clinicians can accurately diagnose a range of sleep disorders, such as obstructive sleep apnea, insomnia, restless legs syndrome, narcolepsy, and other sleep-related conditions. This comprehensive monitoring provides critical insights into sleep quality, breathing irregularities, and overall neurological and respiratory health during sleep.
