Abstract

According to another example, a wearable medical device controller is provided. The device controller includes a memory and a processor coupled to the memory. The processor is configured to determine a correlation between a phenomenon identifiable by the wearable medical device controller and at least one response pattern associated with a patient and store, responsive to detecting the correlation, an adaptation path to address the at least one response pattern, the adaptation path specifying an adaptation of at least one characteristic of an alarm. The at least one response pattern may include a plurality of response patterns and the adaptation path may reflect adaptations made to address at least some of the plurality of response patterns.

Claims

1. An ambulatory medical device comprising:

one or more physiological sensors configured to acquire cardiopulmonary data from a patient, the cardiopulmonary data comprising one or more of electrocardiogram (ECG) data, heart rate data, and respiration data; and

at least one processor operatively coupled to the one or more physiological sensors and configured to

receive at least one user input indicating at least one physical impairment associated with the patient, the at least one physical impairment comprising impaired hearing and the at least one user input comprising a patient response to a hearing test,

detect a cardiac abnormality of the patient based at least on the cardiopulmonary data,

identify a notification associated with the cardiac abnormality of the patient, the notification associated with the cardiac abnormality having one or more characteristics that indicate one or more output conduits for issuing an alarm,

adapt the one or more characteristics of the notification associated with the cardiac abnormality in response to the at least one physical impairment associated with the patient to generate an adapted notification of the cardiac abnormality to have one or more of frequency, amplitude, and tonal quality that corresponds to one or more audio output conduits, and

issue the adapted notification of the cardiac abnormality to the patient.

2. The ambulatory medical device of claim 1, wherein the at least one physical impairment associated with the patient comprises impaired vision.

3. The ambulatory medical device of claim 2, wherein to adapt the one or more characteristics of the notification associated with the cardiac abnormality comprises to alter the notification associated with the cardiac abnormality to include one or more characteristics that correspond to one or more non-visual output conduits.

4. The ambulatory medical device of claim 3, wherein the one or more non-visual output conduits comprise at least one of an auditory conduit and a tactile conduit.

5. The ambulatory medical device of claim 4, wherein the tactile conduit comprises a pattern of vibrations.

6. The ambulatory medical device of claim 1, wherein the at least one physical impairment associated with the patient comprises a mental impairment.

7. The ambulatory medical device of claim 6, the at least one processor being further configured to:

select a second recipient other than the patient to receive the adapted notification of the cardiac abnormality; and

direct the adapted notification of the cardiac abnormality to the second recipient.

8. An ambulatory medical device comprising:

one or more physiological sensors configured to acquire cardiopulmonary data from a patient, the cardiopulmonary data comprising one or more of electrocardiogram (ECG) data, heart rate data, and respiration data; and

at least one processor operatively coupled to the one or more physiological sensors and configured to

receive at least one user input indicating lack of acuity of at least one physical sense of the patient, the at least one physical sense comprising impaired hearing and the at least one user input comprising a patient response to a hearing test,

determine that the lack of acuity of at least one physical sense of the patient is an inhibiting factor for receiving an alarm,

detect a cardiac abnormality of the patient based at least on the cardiopulmonary data,

identify a notification associated with the cardiac abnormality of the patient, the notification associated with the cardiac abnormality having one or more characteristics that indicate one or more output conduits for issuing an alarm,

adapt the one or more characteristics of the notification associated with the cardiac abnormality in response to the lack of acuity of at least one physical sense of the patient to generate an adapted notification of the cardiac abnormality to have one or more of frequency, amplitude, and tonal quality that corresponds to one or more audio output conduits, and

issue the adapted notification of the cardiac abnormality to the patient.

9. The ambulatory medical device of claim 8, wherein the lack of acuity of at least one physical sense of the patient indicates impaired vision.

10. The ambulatory medical device of claim 9, wherein to adapt the one or more characteristics of the notification associated with the cardiac abnormality comprises to alter the notification associated with the cardiac abnormality to include one or more characteristics that correspond to one or more non-visual output conduits.

11. The ambulatory medical device of claim 10, wherein the one or more non-visual output conduits comprise at least one of an auditory conduit and a tactile conduit.

12. An ambulatory medical device comprising:

one or more physiological sensors configured to acquire cardiopulmonary data from a patient, the cardiopulmonary data comprising one or more of electrocardiogram (ECG) data, heart rate data, and respiration data; and

at least one processor operatively coupled to the one or more physiological sensors and configured to

monitor patient data to determine at least one physical impairment associated with the patient, the at least one physical impairment comprising impaired hearing and the patient data comprising a patient response to a hearing test,

detect a cardiac abnormality of the patient based at least on the cardiopulmonary data,

identify a notification associated with the cardiac abnormality of the patient, the notification associated with the cardiac abnormality having one or more characteristics that indicate one or more output conduits for issuing an alarm,

adapt the one or more characteristics of the notification associated with the cardiac abnormality in response to the at least one physical impairment associated with the patient to generate an adapted notification of the cardiac abnormality to have one or more of frequency, amplitude, and tonal quality that corresponds to one or more audio output conduits, and

issue the adapted notification of the cardiac abnormality to the patient.

13. The ambulatory medical device of claim 12, wherein the at least one physical impairment associated with the patient comprises a mental impairment determined based upon analysis of the patient data, the patient data comprising at least one of the cardiopulmonary data, patient motion data, and patient audio data.

14. The ambulatory medical device of claim 13, the at least one processor being further configured to:

select a second recipient other than the patient to receive the adapted notification of the cardiac abnormality; and

direct the adapted notification of the cardiac abnormality to the second recipient.
