Abstract

An example device of a patient includes an antenna configured to wirelessly receive communication from a medical device; and processing circuitry coupled to the antenna and configured to: determine that the received communication indicates that a patient is experiencing an acute health event; in response to the determination, determine one or more physical states of the patient based on sensed data from one or more sensors; confirm that the patient is not experiencing the acute health event based on the determined one or more physical states; and output information based on the confirmation that the patient is not experiencing the acute health event.

First claim

What is claimed is:

1. A system comprising:
an implantable cardiac monitoring device configured to:
determine that a patient is experiencing a sudden cardiac arrest based on sensing by the implantable cardiac monitoring device within the patient; and
transmit a first communication that indicates that the patient is experiencing the sudden cardiac arrest; and

one or more devices of the patient that are different than the implantable cardiac monitoring device, the one or more devices comprising processing circuitry configured to:
determine, based at least in part on the first communication received from the implantable cardiac monitoring device, that the implantable cardiac monitoring device has determined that the patient is experiencing the sudden cardiac arrest;
initiate a request to facilitate delivery of care that is to be provided by one or more care providers or bystanders for medical services to the patient in response to the determination that the implantable cardiac monitoring device has determined that the patient is experiencing the sudden cardiac arrest;
subsequent to initiating the request, confirm that the patient is not experiencing the sudden cardiac arrest based at least in part on a second communication received from the implantable cardiac monitoring device, wherein the second communication received from the implantable cardiac monitoring device is different than the first communication, and wherein the second communication received from the implantable cardiac monitoring device includes at least one of: (1) information from the implantable cardiac monitoring device indicating that the patient is not experiencing the sudden cardiac arrest, or (2) data sensed by the implantable cardiac monitoring device from which the processing circuitry can confirm that the patient is not experiencing the sudden cardiac arrest; and
in response to the confirmation, output information to cause a change in the request for the medical services to one or more of the same one or more care providers or bystanders.

2. The system of claim 1 , wherein the request to facilitate delivery of care comprises a higher-level priority request, and wherein to output the information to cause the change in the request for the medical services, the processing circuitry is configured to output instructions to cease the output of the higher-level priority request and output a lower-level priority request, wherein the lower-level priority request requires fewer medical services as compared to the higher-level priority request.

3. The system of claim 1 , wherein to output the information to cause the change in the request for the medical services, the processing circuitry is configured to cause the one or more devices to output information for an emergency response system of the one or more care providers indicating that the patient is not experiencing the sudden cardiac arrest.

4. The system of claim 1 , wherein the processing circuitry is configured to confirm that the patient is not experiencing the sudden cardiac arrest also based on one or more physical states of the patient, wherein the processing circuitry is configured to determine the one or more physical states of the patient based on sensed data from one or more sensors, wherein the one or more physical states include one or more external physical states, and wherein the one or more external physical states comprise one or more of:
a posture of the patient;
an eye opening;
a face color;
facial tone; or
asymmetrical face or body response.

5. The system of claim 1 , wherein the processing circuitry is configured to confirm that the patient is not experiencing the sudden cardiac arrest also based on one or more physical states of the patient, wherein the processing circuitry is configured to determine the one or more physical states of the patient based on sensed data from one or more sensors, wherein the one or more physical states include one or more internal physical states, and wherein the one or more internal physical states comprise one or more of:
an electrocardiogram;
an intracardiac or intrathoracic impedance;
a respiration rate;
a heart sound;
a pulse;
an oxygenation level;
change in blood volume;
a blood pressure;
change in cardiac rhythm;
change in cardiac rate; or
change in cardiac conduction pattern.

6. The system of claim 1 , wherein the one or more devices include one or more sensors.

7. The system of claim 1 , wherein the processing circuitry is configured to confirm that the patient is not experiencing the sudden cardiac arrest also based on one or more physical states of the patient, wherein the processing circuitry is configured to determine the one or more physical states of the patient based on sensed data from one or more sensors, wherein the one or more sensors comprise a camera of the one or more devices, wherein the sensed data comprises an image of a face of the patient captured with the camera, and wherein to determine the one or more physical states of the patient based on sensed data from one or more sensors, the processing circuitry is configured to, at least one of, determine whether one or both eyes of the patient are open based on the image of the face, or determine a color of the face of the patient.

8. The system of claim 1 , wherein the processing circuitry is configured to confirm that the patient is not experiencing the sudden cardiac arrest also based on one or more physical states of the patient, wherein the processing circuitry is configured to determine the one or more physical states of the patient based on sensed data from one or more sensors, wherein the one or more sensors comprise at least one of an accelerometer or inertial measurement unit (IMU) of the one or more devices, wherein the sensed data comprises information indicative of a posture of the patient, and wherein to determine the one or more physical states of the patient based on sensed data from one or more sensors, the processing circuitry is configured to determine whether the patient is in a vertical posture based on the information indicative of the posture of the patient.

9. The system of claim 1 , wherein the processing circuitry is configured to confirm that the patient is not experiencing the sudden cardiac arrest also based on one or more physical states of the patient, wherein the processing circuitry is configured to determine the one or more physical states of the patient based on sensed data from one or more sensors, wherein the one or more sensors comprise at least one of an accelerometer or inertial measurement unit (IMU) of the one or more devices, wherein the sensed data comprises information indicative of a time-series of positioning of the patient, and wherein to determine the one or more physical states of the patient based on sensed data from one or more sensors, the processing circuitry is configured to determine whether the patient fell based on the information indicative of the time-series of the positioning of the patient.

10. The system of claim 1 , wherein the processing circuitry is configured to confirm that the patient is not experiencing the sudden cardiac arrest also based on one or more physical states of the patient, wherein the processing circuitry is configured to determine the one or more physical states of the patient based on sensed data from one or more sensors, wherein the one or more sensors comprises a microphone of the one or more devices, wherein the sensed data comprises information indicative of sound captured with the microphone, and wherein to determine the one or more physical states of the patient based on sensed data from one or more sensors, the processing circuitry is configured to determine whether the
