Classification: CPC A  G | IPC A  G

Claim 0:
1. A device for detection of a pulse of a subject associated with a cardiopulmonary resuscitation of the subject, the device comprising:
an input unit configured to obtain a series of images of a skin region of the subject associated with the cardiopulmonary resuscitation of the subject; and
a processing unit for processing said series of images, the processing unit being configured to:
detect pulse-related motion of a skin within the skin region of the subject from the series of images;
generate a motion map of the skin region of the subject from the detected pulse-related motion;
derive a dilatation signal reflecting arterial dilatation from the generated motion map;
compare the derived dilatation signal with an expected dilatation signal related to an expected motion map of a skin region for a healthy subject;
determine and indicate a presence of a pulse within the skin region of the subject associated with the cardiopulmonary resuscitation of the subject based on the comparison; and
at least one of:
generate guiding information from a second series of images for guiding an imaging unit for acquiring the series of images or guiding a user for operating the imaging unit to the pulse movement region; and
generate a control signal controlling the imaging unit to switch from a remote mode, in which first images of the skin region are acquired from a distance, to a contact mode, in which second images of the skin region are acquired with the imaging unit being in contact with or in proximity of the skin for the skin region, wherein the second images are used for determining the presence of the pulse.
