Abstract
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.
Claims16
A method for determining the necessity and/or the timing of a treatment against heart malfunctions of a mammal, such as defibrillation or cardiac massage, said method comprising steps of
- applying an arrangement for the non-invasive measurement of the value of the flow of blood to the carotid artery of said mammal,
- determining the value of the flow of the blood into the head of said mammal with said arrangement, and
- producing a helper signal representing the value of the flow of blood into the head of said mammal.
A device for determining the timing and/or the necessity of a treatment against heart malfunctions of a mammal, such as defibrillation or cardiac massage, said device comprising
- an arrangement for the non-invasive measurement of the flow of the blood, said arrangement being adapted to be placed onto the carotid artery of said mammal and
- means for producing a helper signal coupled to said arrangement for the non-invasive measurement of the flow of blood and responsive to the value of the flow of blood measured with said arrangement.
