About Paper:

Novel Noninvasive Device for Continuous Blood Pressure Monitoring Approximately 82.6 million people in the United States suffer from a cardiovascular disease. To prevent the development of many of these cardiovascular diseases, blood pressure must be monitored and controlled. Cuff based technologies for blood pressure measurements are cumbersome, and can be sensitive to motion. Further, these devices give only discrete measurements, offering no insight on blood pressure fluctuation due to activity, white coat syndrome, or masked hypertension. To address the limitations of these technologies, a pressure sensing ring device was designed for the purpose of continuous, noninvasive blood pressure measurement. The device was designed to be comfortable and convenient, and its wireless design will allow for freedom of motion during use. Further, the device's dual sensor design allows it to be robust against motion artifacts, by allowing for common mode rejection of noise. This novel ring utilizes strain gauge technology to measure surface level pressure changes due to arterial pulsation in the finger. Blood pressure can then be calculated by taking into account the extent of attenuation of the blood pressure signals by underlying tissue. The device was tested on human subjects, and the resulting data was compared to simultaneously collected measurements obtained from a gold standard reference device: the Finepres Nova. The subjects varied their blood pressure during these trials by using a leg press machine, allowing for a large range of blood pressure measurements to be taken.
