Description

technical field

[0001] The present invention relates to blood pressure measurement.

[0002] Embodiments of the present disclosure provide methods, devices, devices and systems for measuring arterial blood pressure in humans and mammals. These embodiments use, for example, electromagnetic fields in the microwave spectral range to estimate time-varying arterial diameter. These approaches can be adapted for wearable devices as well as for use by medical practitioners. Background technique

[0003] Sphygmomanometers are currently the most widely used non-invasive device for measuring arterial blood pressure. The detection methods used for this device are the auscultatory technique (Riva-Rocci 1896, Korotkoff 1905) and oscillometric measurements (Geddes 1970). Korotkoff's auscultatory method is the gold standard for noninvasive arterial blood pressure measurement.

[0004] Methods that attempt to estimate arterial blood pressure from pulse wave velocity (eg, Surendhra Goli J...
