Abstract

A system for managing a patient is disclosed and can include a patient interface adapted to obtain ultrasound information about the patient, a provider interface adapted to facilitate communication between the system and a provider, and a controller in communication with the patient interface and the provider interface, the controller including a clinical management module adapted to receive the ultrasound information and to recommend a clinical management strategy based upon the ultrasound information. A method of presenting a clinical management strategy is also described including obtaining information regarding a condition of a patient, developing a determinant reflecting the condition, and presenting a user with a clinical management strategy on an output device.

Claims

1. A method of presenting a clinical management strategy for a patient, the method comprising:

obtaining ultrasound information regarding a condition of the patient from an ultrasound probe, the ultrasound information including cardiovascular function information about the patient;

communicating the ultrasound information to a controller in communication with the ultrasound probe;

employing the controller to develop from the ultrasound information a determinant reflecting the condition of the patient;

developing the clinical management strategy with the controller by determining a status of cardiovascular function and selecting a strategy based on the status of cardiovascular function, wherein determining the status of the cardiovascular function includes;

determining a cardiac output status;

determining a filling pressure status; and

determining a systolic blood pressure status; and

providing on an output device in communication with the controller the clinical management strategy based on the determinant.

2. The method of claim 1, wherein obtaining ultrasound information further comprises selecting an ultrasound probe mode from a plurality of ultrasound probe modes based upon a type of ultrasound information desired.

3. The method of claim 2, wherein the plurality of ultrasound probe modes includes at least one of a 2D image, a color Doppler image, or a spectral Doppler image.

4. The method of claim 2, further comprising selecting another ultrasound probe mode from the plurality of ultrasound probe modes based upon the type of ultrasound information desired.

5. The method of claim 1, wherein obtaining ultrasound information further comprises adjusting the ultrasound probe to an ultrasound probe view, the adjusting being based on a position of the ultrasound probe on the patient and suitable ultrasound probe views available from that position.

6. The method of claim 5, wherein the ultrasound probe is positioned in a cardiovascular window and the suitable ultrasound probe views include a plurality of available cross-sectional views of a cardiovascular system.

7. The method of claim 5, further comprising adjusting the ultrasound probe to another ultrasound probe view, the adjusting being based on the position of the ultrasound probe on the patient and the suitable ultrasound probe views available from that position.

8. The method of claim 1, wherein obtaining ultrasound information further comprises selecting the ultrasound probe from a plurality of ultrasound probes positioned on the patient, the selection being based on ultrasound information available from a respective position.

9. The method of claim 8, further comprising selecting another ultrasound probe from the plurality of ultrasound probes positioned on the patient, the selection being based on information available from another respective position.

10. The method of claim 1, wherein employing the controller to develop a determinant includes determining a category for the cardiac output status or filling pressure status.

11. The method of claim 1, wherein determining the status of the cardiovascular function includes comparing a respective value to a normal value or range of values for at least one of the cardiac output status, the filling pressure status or the systolic blood pressure status.

12. The method of claim 1, wherein the ultrasound probe is configured for temporary attachment to the patient.

13. A method of developing a cardiovascular determinant of a patient, the method comprising:

receiving ultrasound information from a patient interface, the patient interface being adapted to obtain ultrasound information related to cardiovascular function status of the patient, the ultrasound information including a captured ultrasound image clip acquired by the patient interface, the captured ultrasound image clip being reflective of a cardiovascular determinant;

processing the ultrasound information to determine the cardiovascular function status of the patient, the processing including running an image recognition algorithm;

comparing the captured ultrasound image clip to stored ultrasound image clips of an ultrasound image clip database by determining which stored ultrasound image clip or clips the captured ultrasound image clip most closely resembles, the stored ultrasound image clips each reflecting a previously determined category related to the cardiovascular determinant;

categorizing the captured ultrasound image clip; and

sending the status to a clinical management module for the development of a clinical strategy.

14. The method of claim 13, wherein categorizing the captured ultrasound image clip includes assigning a category based on the category of the stored ultrasound image clip or clips that the captured ultrasound image clip most closely resembles.

15. A method of suggesting a clinical management strategy, the method comprising:

comparing a first order data point associated with ultrasound information to a plurality of categories, the first order data point including filling pressure and the plurality of categories including normal and elevated;

comparing another first order data point associated with ultrasound information to a respective plurality of categories, the another first order data point including cardiac output and the respective plurality of categories including low and normal;

assigning a category from the plurality of categories to the first order data point based on which category of the plurality of categories the first order data point falls;

selecting a recommended intervening measure based on the assigned category, wherein, when the cardiac output is low and the filling pressure is elevated, selecting the recommended intervening measure includes selecting a reduction in afterload and a reduction in preload; and

presenting the recommended intervening measure on a display.

17. The method of claim 15, further comprising:

comparing a second order data point to a second respective plurality of categories, wherein the second order data point is associated with ultrasound information; and

assigning a second category from the second respective plurality of categories to the second order data point based on which category of the second respective plurality of categories the second order data point falls;

wherein, selecting a recommended intervening measure is additionally based on the second category.

18. The method of claim 17, wherein the second order data point relates to valvular function.

19. The method of claim 17, wherein the second order data point relates to valvular stenosis.

16. A method of suggesting a clinical management strategy, the method comprising:

comparing a first order data point associated with ultrasound information to a plurality of categories, the first order data point including filling pressure and the plurality of categories including normal and elevated;

comparing another first order data point associated with ultrasound information to a respective plurality of categories, the another first order data point including cardiac output and the respective plurality of categories including low and normal;

assigning a category from the plurality of categories to the first order data point based on which category of the plurality of categories the first order data point falls;

selecting a recommended intervening measure based on the assigned category, wherein, when the cardiac output is low and the filling pressure is normal, selecting an intervening measure includes selecting a reduction in afterload and selecting to maintain the preload; and

presenting the recommended intervening measure on a display.
