Sleep Apnea is a disorder that affects 22 million Americans. This occurs when throat muscles relax and intermittently block the airway and prevent breathing. The body’s response is to jolt awake, disrupting sleep patterns repeatedly throughout the night. If sleep apnea is left untreated, it can lead to high blood pressure, chronic heart failure and stroke. 85% of cases are left undiagnosed, which adds approximately $3.4 million to US health care costs annually. RespiRadar is a non-contact respiration detection and classification radar system for better diagnosis of sleep apnea. Ultrawideband radar was chosen for this application because it has low power consumption and high resolution. The radar is placed under the patient’s bed during the night and sends radio frequency pulses that penetrate through the bed to pick up on breathing patterns during the night. The device classifies breathing patterns over time in order to warn users about irregularities.
