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

at least one processor coupled to the memory and configured to;

detect an occurrence of the event;

issue a first instance of the alarm;

determine that no predetermined response to the first instance of the alarm was received within a target response time;

adapt, responsive to determining that no predetermined response was received within the target response time, at least one characteristic of the alarm at least in part by changing a conduit of the alarm to a different sensory output according to an adaptation path of the plurality of adaption paths; and

issue a second instance of the alarm, the second instance of the alarm having the at least one adapted characteristic.

2. The wearable medical device controller according to claim 1, wherein the at least one processor can:

detect a phenomenon; and

adapt, responsive to detecting the phenomenon and prior to issuance of the first instance of the alarm, one or more characteristics of the alarm according to the adaptation path.

3. The wearable medical device controller according to claim 1, wherein the at least one processor can:

determine a correlation between a value of an independent variable indicative of a phenomenon and at least one response pattern; and

create the alarm profile where the correlation exceeds a predetermine threshold.

4. The wearable medical device controller according to claim 1, wherein the at least one processor can adapt the at least one characteristic of the alarm at least in part by increasing an intensity of the alarm.

5. The wearable medical device controller according to claim 1, wherein the at least one processor can adapt the at least one characteristic of the alarm at least in part by changing a conduit of the alarm.

6. The wearable medical device controller according to claim 1, wherein the at least one processor can adapt the at least one characteristic of the alarm at least in part by changing a conduit of the alarm to transmit the alarm to a personal electronic device.

7. The wearable medical device controller according to claim 1, wherein the at least one processor can:

detect an inhibiting factor; and

adapt, responsive to detecting the inhibiting factor and prior to issuance of the first instance of the alarm, one or more characteristics of the alarm according to the adaptation path.

8. The wearable medical device controller according to claim 1, further comprising an interface in data communication with the at least one processor, wherein the at least one processor can:

receive a new alarm profile via the interface; and

store the new alarm profile in the memory.

9. The wearable medical device controller according to claim 1, further comprising an interface in data communication with the at least one processor, wherein the at least one processor can:

receive a new alarm profile via the interface;

store the new alarm profile in the memory;
