Problems solved by technology

[0015] However, all those features for blood pressure values ​​are not robust enough to gain changes due to electronic drift, skin color, sensor-skin interface and / or do not provide a sufficiently accurate blood pressure measurement

Embodiment Construction

[0037] figure 2 An embodiment of a device 10 for determining a blood pressure value is shown. The device 10 includes a pulse signal part 11 , a pulse selection part 12 , a calculation part 13 and a user characteristic part 18 .

[0038] The heartbeat section 11 is configured to provide a heartbeat signal. In one embodiment, the heartbeat portion 11 may simply be an interface configured to receive data representing a heartbeat. In another embodiment, the pulsatile signal portion 11 may be or include a pulsatile sensor for measuring a pulsatile signal of a user. A pulsatile signal can be defined as a signal that contains information about blood flow and periodic changes in arterial diameter for a given portion of the arterial tree. Periodic variations are generally generated by the arrival of a pressure pulse at a given portion of the arterial tree.

[0039] In one embodiment, the pulsation sensor is a PPG sensor. PPG sensors can be transmissive or reflective based. imag...

Abstract

Method for determining a blood pressure value comprising the steps of: providing a pulsatility signal (1), determining a time-related feature and a normalized amplitude-related feature on the basis ofthe pulsatility signal; and calculating a blood pressure value on the basis of a blood pressure function depending on the time-related feature, the normalized amplitude-related feature and function parameters.

Description

technical field [0001] The invention relates to methods, devices and computer programs for determining blood pressure values. Background technique [0002] Blood pressure is the pressure exerted by circulating blood on the walls of blood vessels. Usually measured in terms of systolic pressure (the maximum pressure in the artery during the cardiac cycle), diastolic pressure (the minimum pressure in the artery during the cardiac cycle) or pulse pressure (the difference between the systolic and diastolic values ) to represent human blood pressure. [0003] Systolic, diastolic and pulse pressure values ​​are used to detect certain health or fitness conditions of the body and / or to detect disease. [0004] However, in order to measure systolic, diastolic or pulse pressure values, blood pressure signals need to be measured via an invasive sensor (a sensor located inside an artery). [0005] In recent times there have been many attempts to provide estimates of blood pressure val...
