The NIBP100A is a noninvasive blood pressure monitor that uses a pressure sensor placed on the wrist over the radial artery. This device uses a "sweep technique," which applies a varying force on the radial artery. The counter-pressure in the artery produces a signal which is digitized and used to calculate blood pressure parameters. With just a few easy calibration steps, the NIBP100A and AcqKnowledge work together to provide automated, continuous, noninvasive blood pressure measurements.
