摘要
A simultaneous monitoring system for non-invasive blood pressure and blood oxygen saturation based on the volume-oscillometric method and the dual-wavelength spectrophotometry is developed. The principle of the volume-oscillometric method and the dual-wavelength spectrophotometry for measurement of blood pressure and blood oxygen saturation is introduced in this paper, and the newly developed local pressurizing cuff unit and the photoplethysmography sensor unit are used in the system. A performance and comparative experiment using the system is carried out. The experimental result shows that the local pressurizing cuff can effectively depress artery at wrist, and the photoplethysmography sensor unit is suitable for detecting the absorption of venous and arterial blood to reflected light. The experimental result also shows that the system can accurately detect non-invasive blood pressure, arterial oxygen saturation and venous oxygen saturation
