Abstract

A medical device is disclosed that includes a service component for use in detecting patient data, at least one processor coupled with the service component, a care protocol module executable by the at least one processor to provide healthcare to a patient at least in part by generating a request for processing by the service component, and a resource module executable by the at least one processor to manage access to the service component by identifying a level of service associated with the care protocol module and responding to the request by managing the service component to meet the level of service. The care protocol module implements a patient care protocol that includes a sequence of actions directed to the patient. The level of service indicates a level of performance that the patient care protocol requires of the resource module. Selective offloading of modular functions is also enabled.

Claims

1. A medical device comprising:

a service component configured to detect patient data;

at least one processor coupled to the service component;

a first care protocol module executable by the at least one processor to provide healthcare to a patient at least in part by generating a first request for processing by the service component; and

a resource module executable by the at least one processor to manage access to the service component by

identifying a level of service associated with the first care protocol module, and

responding to the first request by managing the service component to meet the level of service,

wherein

the first care protocol module implements a patient care protocol that includes a sequence of actions directed to the patient;

the level of service indicates a level of performance that the first care protocol requires of the service component; and

the resource module includes an electrocardiogram rhythm analysis resource module and is executable by the at least one processor to respond to requests from at least the first care protocol module that fall within a predetermined time window with a single calculated instance of cardiac rhythm data.

2. The medical device of claim 1, further comprising:

a second care protocol module executable by the at least one processor to provide additional healthcare to the patient at least in part by generating a second request for processing by the service component; and

a conflict arbitration engine executable by the at least one processor to resolve conflicts between multiple requests for processing by the service component at least in part by

comparing the multiple requests,

identifying a source component associated with at least one request of the multiple requests, and

initiating processing of the at least one request.

3. The medical device of claim 1, wherein the resource module is executable by the at least one processor to respond to the first request at least in part by

translating the level of service into an allocation requirement for a capacity of the service component, and

managing the service component includes allocating the capacity of the service component to the first request according to the allocation requirement.

4. The medical device of claim 3, wherein

the service component comprises at least one electrode,

the first care protocol module implements a heart monitoring protocol,

the resource module includes an electrocardiogram (ECG) beat detection resource module, and

the allocation requirement includes receiving ECG data sampled at a frequency of 250 Hz or greater.

5. The medical device of claim 3, wherein

the service component comprises at least one electrode,

the first care protocol module implements a cardiopulmonary resuscitation protocol, and

the resource module includes a compression resource module.

6. The medical device of claim 3, further comprising a second care protocol module executable by the at least one processor to provide additional healthcare to the patient at least in part by generating a second request for processing by the service component, wherein

the first care protocol module implements a heart monitoring protocol, and

the second care protocol module implements a cardiopulmonary resuscitation protocol.

7. The medical device of claim 3, further comprising a second care protocol module executable by the at least one processor to provide additional healthcare to the patient at least in part by generating a second request for processing by the service component, wherein the resource module is executable by the at least one processor to

identify a higher priority request and a lower priority request from the first request and the second request, and

at least temporarily deny processing of the lower priority request in favor of processing of the higher priority request.

8. The medical device of claim 7, wherein

the service component comprises a defibrillation subsystem,

the first care protocol module implements a manual charging protocol,

the second care protocol module implements a silent charging protocol, and

the resource module includes a defibrillation control resource module.

9. The medical device of claim 8, wherein the resource module is executable by the at least one processor to identify the second request as the lower priority request where the second request is received after the first request.

10. The medical device of claim 3, further comprising:

a second care protocol module executable by the at least one processor to provide additional healthcare to the patient at least in part by generating a second request for processing by the service component; and

a conflict arbitration engine executable by the at least one processor to resolve conflicts between multiple requests for processing by the service component at least in part by

receiving an arbitration request indicating the multiple requests,

comparing the multiple requests,

identifying a lower priority request of the multiple requests as being from a source component associated with a lower priority, and

transmit a notification indicating the lower priority request.

11. The medical device of claim 10, wherein
