Abstract

An algorithm has been developed for a Public Access Defibrillator which utilizes distinctive features from the impedance cardiogram (ICG) recorded via defibrillator pads to advise both lay users and minimally trained bystanders to ensure CPR effectiveness. Following ethical approval, data were collected and marked. CPR was administered by trained personnel. 211 cases were gathered and the training set included 106 cases. A retrospective analysis was carried out of simultaneously recorded ECG and ICG. The speed of compressions was calculated by counting the outstanding waves in the ICG during CPR. Also if the base-to-peak amplitude of the ICG is greater than a minimum threshold, the corresponding compressions were classified as being applied with adequate force. For the validation set, adequate speed was detected with 91.45% sensitivity and 96.27% specificity (79826s) and adequate force with 99.94% sensitivity and 97.91% specificity (91973s).
