Abstract:
Many research groups have studied blood pressure measurement in finger artery because of its convenience. But, low accuracy prohibits many hypertension patients from using this device. So, we suggest measurement algorithm that measure systolic and diastolic blood pressure in finger artery. And we also develop calibration method that decreases the error from difference of finger circumference by subjects. We apply our methods for 90 subjects (age form 20 to 49, 55 male, 35 female) to test feasibility of our method by AAMI SP10 standard. The mean difference of our system is ±4.7mmHg for systolic pressure, ±4.2mmHg for systolic pressure. It proved that the feasibility of our method is clinically acceptable.(under ±5mmHg).

This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
