Method and device for producing a helper signal

摘要

With a method and a device for producing a helper signal for determining the point in time for a defibrillation or a cardiac massage given a cardiac arrest, the value (W) of the blood flow (B) into the head of the patient affected by the heart malfunctioning is used in order on the one hand to determine the necessity for activating the reanimation impulse (current shock/cardiac massage) and in order on the other hand to indicate whether the blood supply of the brain is sufficient.In order to be able to quickly lay the arrangement for measuring the blood flow onto the carotid artery, the measuring arrangement (10) consists of a multidude of individual flow measuring units (11, 11') arranged next to one another.
