Demonstration of a Remote Optical Measurement Configuration That Correlates With Breathing, Heart Rate, Pulse Pressure, Blood Coagulation, and Blood Oxygenation

摘要

An optical approach to the extraction and separation of remote vibration sources has recently been proposed. The technique has previously been applied successfully to biomedical measurements including pulse pressure, heart rate, blood glucose and alcohol concentrations, and intraocular pressure. In this paper, we review this optical sensing technology and demonstrate its ability to monitor three additional biomedical indicators, breathing, blood oximetry, and blood coagulation, as well as its ability to simultaneously monitor indicators that were previously only monitored separately. The proposed compact and potentially low-cost biomedical sensor can be highly beneficial given the global healthcare challenges, especially in the developing countries.
