Abstract
Systems and methods are disclosed herein for maintaining the calibration of non-invasive blood pressure monitoring devices. Phase components of pulse signals detected by the blood pressure monitoring device are compared to stored baseline phase component values. If the difference exceeds a threshold, the blood pressure monitoring device is recalibrated.
