Abstract
A system for measuring and analyzing CPR parameters for use with and by an external defibrillator, where a pressure sensitive electrode is connected to a defibrillator, in addition to the standard electrodes of the defibrillator. The information from the pressure sensitive electrode, together with information derived from modulation of the impedance of the thorax, measured by the defibrillator, describes the quality of the CPR performed, and is used to generate voice messages that increase the quality and the effectiveness of the CPR. The defibrillator may in addition be equipped with a transmission device that sets up a radio connection with an emergency center. The emergency center is equipped with a display unit that shows the activities at the resuscitation site. In addition to the data transfer link, a speech connection is set up via a microphone and a speaker on the resuscitation site and a microphone and auditory unit at the emergency center, in order to allow an operator at the emergency center to intervene and direct the attempt at resuscitation during the critical phases following the electrical shocks. During training and practice, the defibrillator or the training defibrillator will receive information from sensors placed in the manikin regarding the CPR performance, and will then use this information to give instructions.
