Method and device for evaluating pain in a living being

摘要

The method involves acquiring an analog cardiac signal of a living being, sampling the signal, and constructing a series constituted of samples. Samples contained in a main time window is selected and the window is divided into sub-windows (F j). An area (A j) is calculated, for each sub-window, from the samples in the sub-windows. A final parameter correlated with intensity of painful stimulus is calculated according to the areas. The samples constituting the series represent time intervals which separate two successive cardiac pulsations. An independent claim is also included for a device for evaluating pain level in a living being.
