  • Method for non-evasively determining an endothelial function and a device for carrying out said method
    Patent number: 10238306
    Abstract: The invention relates to medicine. The inventive method for non-evasively determining an endothelial function consists in reducing a transmural pressure in a limb, recording the amplitude of plethysmographic signals at different pressures, determining the pressure of a maximum plethysmographic signal amplitude, reducing the pressure to a value corresponding to the specified percentage of the maximum amplitude, carrying out an occlusion sample in the course of which a pressure higher by at least 50 mm Hg than the systolic pressure of a tested patient is produced in a cuff arranged proximally to the located limb area, wherein the occlusion is carried out during at least 5 minutes.
