Abstract
A method for calibrating a blood pressure monitoring system includes activating a reference monitor to perform a reference measurement of the blood pressure of a user as part of a calibration process. A wearable sensing device is activated to detect a parameter of user that is correlatable to the user's blood pressure. A processor of the user interface device processes the at least one parameter detected by the wearable blood pressure sensing device with reference to the reference measurement to determine a correlation factor that correlates the at least one parameter detected by the wearable blood pressure sensing device to the blood pressure of the user. The reference measurement includes an inflation phase, a measurement phase and a deflation phase. The processor is configured to only use the at least one parameter detected by the wearable blood pressure sensing device during the measurement phase in determining the correlation factor.
