Abstract
A medical device can include a housing, an energy storage module within the housing to store an electrical charge, and a defibrillation port to guide via electrodes the stored electrical charge to a person in need of medical assistance. The medical device can also include a processor to analyze patient physiological signal(s) that indicate heart viability. Positive measures of heart viability measures can qualify the patient for a customized treatment paradigm.
Claims21
1-20. (canceled)
A system, comprising:
- a chest compression device configured to administer chest compressions to a patient;
- and
- a defibrillator comprising:
- a measurement circuit configured to detect an electrocardiogram (ECG) of the patient;
- a sensor configured to detect a non-ECG physiological parameter of the patient;
- a treatment circuit configured to output an electrical shock to the patient;
- and
- a processor configured to:
- determine a viability index of the patient by:
- determining that the ECG is indicative of coarse ventricular fibrillation (VF);
- and
- determining that the non-ECG physiological parameter of the patient is above a first threshold;
- cause the treatment circuit to output the electrical shock to the patient;
- determine that a heart viability of the patient is sufficient by comparing the viability index to a second threshold;
- and
- in response to determining that the heart viability of the patient is sufficient, output, to the chest compression device, an instruction to pause the chest compressions after the electrical shock is administered to the patient.

A method, comprising:
- determining that an ECG of a patient is indicative of VF or ventricular tachycardia (VT);
- determining a viability index of the patient by analyzing the ECG of the patient;
- in response to determining that the ECG of the patient is indicative of VF or VT, causing an electrical shock to be administered to the patient;
- determining that a heart viability of the patient is sufficient by comparing the viability index to a threshold;
- and
- in response to determining that the heart viability of the patient is sufficient, delaying administration of chest compressions after the electrical shock is administered to the patient.
