Abstract
An apparatus and method provides improved guidance instructions to providers of cardiopulmonary resuscitation (CPR) compressions in a cardiac arrest event. The apparatus detects CPR rate and/or changes in CPR rate, and issues prompts related to checking the depth of compressions based upon the rate/rate change detection. The prompts may be aural or visual.
Claims15
An automated external defibrillator for guiding the application of cardiopulmonary resuscitation (CPR) compressions, comprising:
- a pair of electrodes configured to obtain electrical signals related to changes in a transthoracic impedance related to a plurality of CPR compressions;
- a front end circuit in electrical communication with the pair of electrodes and configured to convert the electrical signals into a plurality of CPR compressions signals;
- a hardware processor in communication with the front end circuit and configured to determine a CPR rate and a change in the CPR rate based upon the plurality of CPR compressions signals;
- and
- a user output configured to issue at least an aural CPR guidance prompt related to adjusting the depth of compression based upon a determined change in the CPR rate.

A method for improving CPR guidance, comprising the steps of:
- providing a device for guiding the application of cardiopulmonary resuscitation (CPR) compressions, the device including a housing, a sensor operable to detect a parameter related to a CPR compression and to output the parameter, a processor disposed in the housing, the processor configured to receive the parameter from the sensor, determine a CPR rate based on the parameter and determine a change in CPR rate from the CPR rate, and a user output configured to issue a CPR guidance prompt related to adjusting the depth of compression based upon the determined change in CPR rate;
- automatically detecting the change in the CPR rate by the device;
- and
- issuing a guidance instruction related to a depth of compression based on the automatically detecting step.
