Abstract

In one embodiment, a method to alert a user of a wearable cardioverter defibrillator (WCD) is described. The method includes detecting a condition requiring attention of the patient and issuing an alert to notify the patient of the condition. The method also includes receiving a first input from the patient to replay the audible portion of the alert and replaying the audible portion of the alert when the first input is received.

Claims (53)

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

detecting a condition related to the patient and/or the WCD;

issuing an alert to notify the user and/or the patient of the condition;

receiving an input from the user and/or the patient to cause the WCD to enter a silent mode to silence the alert; and

during the silent mode:

determining that the condition has been resolved,

receiving a first input from the user and/or the patient to replay a portion of the alert; and

replaying the portion of the alert and an indication that the condition has been resolved when the first input is received.

2. The method of claim 1 , wherein the portion of the alert comprises at least one of an audible portion of the alert or a visual portion of the alert.

3. The method of claim 1 , wherein the condition comprises at least one of a health status of the patient or a status of the WCD.

4. The method of claim 1 , further comprising: exiting the silent mode after a predetermined period of time.

5. The method of claim 4 , wherein the predetermined period of time is greater than five minutes.

6. The method of claim 1 , wherein the alert comprises more than one alert, the method further comprising: replaying the more than one alert in an order of a predetermined priority.

7. The method of claim 1 , wherein the alert comprises an audible portion comprising a sound alert and a voice alert.

8. The method of claim 7 , wherein in replaying the audible portion further comprises:

replaying only the voice alert of the audible portion of the alert in response to receiving the first input.

9. The method of claim 1 , further comprising:

playing a status alert message prior to replaying the portion of the alert.

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

a support structure configured to be worn by the patient; and

one or more processors configured to cause the WCD system to:

detect a condition related to the patient and/or the WCD;

issue an alert to notify the patient and/or a user of the condition;

receive a selection from the patient and/or the user to cause the WCD to enter a silent mode; and

during the silent mode:

determine that the condition has been resolved,

receive an input from the patient and/or the user to replay a portion of the alert, and

replay the portion of the alert and an indication that the condition has been resolved in response to the input being received.

11. The WCD system of claim 10 , wherein the portion of the alert comprises at least one of an audible portion or a visual portion.

12. The WCD system of claim 10 , wherein the condition comprises at least one of a health status of the patient or a status of the WCD.

13. The WCD system of claim 10 , wherein the one or more processors are further configured to cause the WCD system to: exit the silent mode after a predetermined period of time.

14. The WCD system of claim 13 , wherein the predetermined period of time is greater than five minutes.

15. The WCD system of claim 10 , wherein the alert comprises more than one alert, wherein the one or more processors are further configured to cause the WCD system to:

replay the more than one alert in an order of predetermined priority.

16. A wearable cardioverter defibrillator (WCD) system for monitoring health of a patient using the WCD system, the system comprising:

a support structure configured to be worn by the patient;

a plurality of sensors to detect one or more conditions, wherein at least one sensor of the plurality of sensors is configured to be coupled to the support structure;

one or more displays; and

one or more processors configured to cause the WCD system to:

detect a condition related to the patient and/or the WCD system;

issue an alert to notify the patient and/or a user of the condition;

receive an input from the patient and/or the user to cause the WCD system to enter a silent mode to silence the alert; and

during the silent mode:

determine that the condition has been resolved,

receive a second input from the patient and/or the user to replay a portion of the alert,

play a status alert message prior to replaying the portion of the alert, and

replay the portion of the alert and an indication that the condition has been resolved when the second input is received.

17. The WCD system of claim 16 , wherein the portion of the alert comprises at least one of an audible portion or a visual portion.

18. The WCD system of claim 16 , wherein the condition comprises at least one of a health status of the patient or a status of the WCD system.

19. The WCD system of claim 16 , wherein the one or more processors are further configured to cause the WCD system to:

exit the silent mode after a predetermined period of time.

20. The WCD system of claim 16 , wherein the alert comprises more than one alert, wherein the one or more processors are further configured to cause the WCD system to:

replay the more than one alert in an order of predetermined priority.
