Studies from Shanghai Jiao Tong University Provide New Data on Sleep Apnea (Noncontact Infant Apnea Detection for Hypoxia Prevention With a k-band Biomedical Radar).

A study conducted by Shanghai Jiao Tong University in China has developed a non-contact technique for monitoring infant cardiopulmonary activity and detecting apnea using a custom-designed K-band biomedical radar sensor system. The radar technology allows for the detection of chest movements without physical contact, providing valuable information about an infant's respiration and heartbeat. The proposed algorithm adjusts the threshold and warning time to measure the number and duration of apneic events. Clinical experiments have shown that this method effectively monitors cardiopulmonary signals and apneas of varying durations, suggesting potential applications in both clinical and non-clinical settings.
