Non-contact sleep atrial fibrillation monitoring using fiber optic sensors

This study presents a fiber optic monitoring pillow (FOMP) designed for non-contact sleep monitoring of patients with atrial fibrillation (AF). The FOMP employs fiber optic sensors to capture respiratory and cardiac waveforms, enabling the extraction of physiological parameters such as heart rate and respiratory rate. In a clinical trial involving AF patients, the FOMP successfully detected effective ballistocardiogram signals using a non-contact approach for the first time, demonstrating a high correlation with electrocardiogram data, as evidenced by a Pearson's correlation coefficient of 0.984. Additionally, the FOMP effectively identified abnormal respiration patterns indicative of sleep apnea. This non-invasive monitoring technique offers a valuable tool for the early detection and continuous assessment of cardiovascular health, underscoring its potential for integration into routine health monitoring protocols.
