Abstract

Claims (30)

1 . A wearable cardiac defibrillator (WCD) system for monitoring health of a patient wearing the WCD system, the WCD system comprising:

a support structure configured to be worn by the patient;

one or more electrocardiogram (ECG) electrodes;

one or more defibrillator electrodes configured to be proximate to the patient when the patient is wearing the WCD system; and

a processor communicatively coupled to the one or more ECG electrodes,

wherein the processor is configured to:

detect an abnormality, wherein the abnormality includes at least one of a battery anomaly, a loss of connectivity of the one or more ECG electrodes, a loss of connectivity of the one or more defibrillator electrodes, or a connectivity issue between the processor and an external device;

issue a system alert based, at least in part, on the detection of the abnormality, wherein the system alert changes a brightness of one or more LEDs from a first level to a second level;

monitor a status of the abnormality;

determine that the status of the abnormality is resolved; and

issue an alert responsive to the determination that the status of the abnormality is resolved, wherein the alert changes the brightness of the one or more LEDs from the second level to the first level.

2 . The WCD system of claim 1 , wherein the processor is further configured to cause a change in a luminous intensity of the one or more LEDs.

3 . The WCD system of claim 1 , wherein the processor is further configured to cause the one or more LEDs to illuminate based on a patient status.

4 . The WCD system of claim 3 , wherein the processor is further configured to:

deactivate at least one of the one or more LEDs after a predetermined threshold has been satisfied.

5 . The WCD system of claim 3 , wherein the processor is further configured to:

alter a color of the one or more LEDs.

6 . The WCD system of claim 1 , wherein the processor is further configured to cause two or more LEDs to illuminate in a sequential and a syncing pattern.

7 . A method to alert a user of a wearable cardioverter defibrillator (WCD), the method comprising:

detecting an abnormality in the WCD, wherein the abnormality includes at least one of a battery issue, an electrocardiogram (ECG) connectivity issue, an electrode connectivity issue, a lead being disengaged from the WCD, or a connectivity issue;

issuing a system alert responsive, at least in part, to the detection of the abnormality, wherein the system alert changes a brightness of one or more LEDs from a first level to a second level;

monitoring a status of the abnormality;

determining that the status of the abnormality is resolved; and

issuing an alert responsive to the determination that the status of the abnormality is resolved, wherein the alert comprises a change in the brightness of the one or more LEDs from the second level to the first level.

8 . The method of claim 7 , further comprising:

altering a pattern of illumination of the one or more LEDs.

9 . The method of claim 7 , further comprising:

deactivating at least one of the one or more LEDs after a predetermined threshold has been satisfied.

10 . The method of claim 7 , further comprising:

controlling a color of at least two LEDs, wherein at least a first LED is a first color and at least a second LED is a second color.
