Abstract

A system and method are implemented to identify pulmonary congestion in a subject. The system and method detect pulmonary congestion in a subject based on one or more parameters of the breathing of the subject. The detection of pulmonary congestion in the subject may be relatively passive for the subject. This may enhance the convenience and/or comfort of compliance to a detection regime by the subject. By detecting pulmonary congestion in the subject, potential episodes of heart failure may be identified and/or averted. The system and method may be configured to facilitate treatment of the subject to remediate detected pulmonary congestion and/or avert potential episodes of heart failure. For example, the system may provide enhanced access for a caregiver to detections of parameters related to pulmonary congestion in the subject.

Claims

1. A system configured to monitor pulmonary congestion in a subject, the system comprising:

a user interface configured to enable a user to interact with the system;

one or more processors configured to implement a plurality of computer program modules, the computer program modules comprising;

a parameter module configured to receive output signals from one or more sensors configured to monitor gas breathed by a subject, the output signals conveying information about the gas breathed by the subject, the parameter module being further configured to determine one or more parameters of the breathing of the subject from the received output signals;

a congestion monitor module configured to identify pulmonary congestion in the subject based on the one or more parameters of the breathing of the subject determined by the parameter module; and

a notification module configured to control the user interface to provide a notification to the user of pulmonary congestion in the subject, if the congestion monitor module identifies pulmonary congestion in the subject.

2. The system of claim 1, wherein the user is the subject.

3. The system of claim 1, wherein the user is a caregiver to the subject.

4. The system of claim 3, wherein the user interface includes a graphical user interface that is presented to the user on a terminal located remotely from the one or more sensors.

5. The system of claim 1, wherein the one or more parameters of the breathing of the subject indicate one or both of lung compliance and/or Cheyne-Stokes respiration.

6. A method of monitoring pulmonary congestion in a subject, the method comprising:

receiving output signals at one or more processors from one or more sensors configured to monitor gas breathed by a subject, the output signals conveying information about the gas breathed by the subject;

implementing one or more computer program modules on the one or more processors to determine one or more parameters of the breathing of the subject from the received output signals;

implementing one or more computer program modules on the one or more processors to identify pulmonary congestion in the subject based on the determined one or more parameters of the breathing of the subject; and

implementing one or more computer program modules on the one or more processors to control a user interface to provide a notification to a user of identified pulmonary congestion in the subject.

7. The method of claim 6, wherein the user is the subject.

8. The method of claim 6, wherein the user is a caregiver to the subject.

9. The method of claim 8, wherein the user interface includes a graphical user interface that is presented to the user on a terminal located remotely from the one or more sensors.

10. The method of claim 6, wherein the one or more parameters of the breathing of the subject indicate one or both of lung compliance and/or Cheyne-Stokes respiration.

11. A system configured to monitor pulmonary congestion in a subject, the system comprising:

means for receiving output signals at one or more processors from one or more sensors configured to monitor gas breathed by a subject, the output signals conveying information about the gas breathed by the subject;

means for determining one or more parameters of the breathing of the subject from the received output signals;

means for identifying pulmonary congestion in the subject based on the determined one or more parameters of the breathing of the subject; and

means for controlling a user interface to provide a notification to a user of identified pulmonary congestion in the subject.

12. The system of claim 11, wherein the user is the subject.

13. The system of claim 11, wherein the user is a caregiver to the subject.

14. The system of claim 13, wherein the user interface includes a graphical user interface that is presented to the user on a terminal located remotely from the one or more sensors.

15. The system of claim 11, wherein the one or more parameters of the breathing of the subject indicate one or both of lung compliance and/or Cheyne-Stokes respiration.
