Abstract
A pad carrying an array of ECG electrodes can be used to measure ECG signal amplitudes and AMSA, a signal analyzer determines a cardiac position with respect to the pad, and an indication of cardiac position with respect to indicia can be provided on a top surface of the pad for output to the user to guide in performing chest compressions during CPR. The pad may integrate a defibrillator electrode. The apparatus may be an automated external defibrillator (AED).
Claims22
An apparatus for determining a location of a heart on a patient, the apparatus comprising:
- a pad carrying an array of ECG electrodes to be placed over an area of the heart on a patient's chest;
- a plurality of body electrodes;
- an ECG device connectable to said pad and said plurality of body electrodes for generating an ECG signal for each electrode of said array of ECG electrodes;
- and
- a signal analyzer connectable to said ECG device for determining a location with respect to said array of ECG electrodes corresponding to a location of heart ventricles.
13-14. (canceled)
(canceled)
A cardiopulmonary resuscitation (CPR) system comprising:
- a pad carrying an array of ECG electrodes to be placed over an area of the heart on a patient's chest;
- a plurality of body electrodes;
- an ECG device connectable to said pad and said plurality of body electrodes for generating an ECG signal for each electrode of said array of ECG electrodes;
- a signal analyzer connectable to said ECG device for determining a location with respect to said array of ECG electrodes corresponding to a location of heart ventricles;
- a chest compression motor drive having a chest compression pad connected to a vacuum pump;
- a frame connectable to a panel to be placed under a back of a patient, said frame supporting said chest compression motor drive;
- and
- one of:
- a CPR guidance interface controlled by the signal analyzer to indicate the location of the heart ventricles to guide a technician to position the frame to have the chest compression pad positioned over the heart ventricles;
- or
- a positioning actuator mounted to the frame, wherein the pad is at a known location with respect to the frame and the positioning actuator is connected to said signal analyzer to position the chest compression pad at the location of the heart ventricles.
