Graphical representation of hemodynamic state

1 . A method implemented using one or more processors, comprising:

analyzing one or more measured physiological parameters of a patient;

based on the analyzing, causing a graphical user interface to be rendered, wherein the graphical user interface includes a single figure-eight schematic that represents a circulatory system of the patient, the figure-eight schematic comprising two closed, continuous loop paths that directly meet and are contiguous with a single central rounded object, wherein:

a first loop of the figure-eight schematic represents pulmonary circulation of the patient;

a second loop of the figure-eight schematic represents systemic circulation of the patient;

the central object that connects the first and second loops represents a heart of the patient and is shaped to convey an end diastolic volume (EDV) of the patient, and at least a portion of the first loop is superimposed over a rendered pair of lungs, and

each of the first and second loops includes multiple contiguous arc fragments, with each arc fragment being shaped to convey one or more of the measured physiological parameters of the patient, wherein cardiac output of the patient is conveyed by a length of an arc fragment of the second loop that extends from the central rounded object.

2 . The method of claim 1 , comprising:

rendering a first arc fragment of the first loop upstream of an arc-shaped envelope with an arc-shaped channel, with a first thickness that is selected to convey a mean pulmonary arterial pressure (MPAP) of the pulmonary circulation of the patient; and

rendering a second arc fragment of the first loop downstream of the arc-shaped envelope, with a second thickness that is selected to convey pulmonary artery occlusion pressure (PAOP) of the pulmonary circulation of the patient.

3 . The method of claim 1 , comprising:

rendering a first arc fragment of the second loop with a third thickness that is selected to convey a mean arterial pressure (MAP) of the systemic circulation of the patient, the first arc fragment positioned upstream of an arc-shaped envelope with an arc-shaped channel; and

rendering a second arc fragment of the second loop downstream of the arc-shaped envelope with a fourth thickness that is selected to convey central venous pressure (CVP) of the systemic circulation of the patient.

4 . The method of claim 1 , wherein a stroke volume of the patient is conveyed by a length of a secondary arc-shaped element that extends from within the arc fragment of the second loop.

5 . The method of claim 1 , comprising:

rendering an arc-shaped envelope with an arc-shaped channel, wherein a bore of the arc-shaped channel is sized to convey vascular resistance by constricting a thickness of a portion of the first or second loop.

6 . The method of claim 1 , wherein one or more of the multiple arc fragments include visual annotations of normal or baseline ranges of the respective one or more of the measured physiological parameters of the patient.

7 . The method of claim 1 , comprising animating the pair of lungs to demonstrate breathing of the patient.

8 . The method of claim 1 , comprising rendering the pair of lungs with a visual annotation that represents a level of extravascular lung water (EVLW) of the patient.

9 . At least one non-transitory computer-readable medium comprising instructions that, in response to execution of the instructions by one or more processors, cause the one or more processors to perform the method of claim 1 .

10 . A system comprising one or more processors and memory storing instructions that, in response to execution of the instructions by the one or more processors, cause the one or more processors to:

analyze one or more measured physiological parameters of a patient;

based on the analysis, cause a graphical user interface to be rendered, wherein the graphical user interface includes a single figure-eight schematic that represents a circulatory system of the patient, the figure-eight schematic comprising two closed, continuous loop paths that directly meet and are contiguous with a single central rounded object, wherein:

a first loop of the figure-eight schematic represents pulmonary circulation of the patient;

a second loop of the figure-eight schematic represents systemic circulation of the patient;

the central object that connects the first and second loops represents a heart of the patient and is shaped to convey an end diastolic volume (EDV) of the patient, and at least a portion of the first loop is superimposed over a rendered pair of lungs,

each of the first and second loops includes multiple contiguous arc fragments, with each arc fragment being shaped to convey one or more of the measured physiological parameters of the patient, wherein cardiac output of the patient is conveyed by a length of an arc fragment of the second loop that extends from the central rounded object.

11 . The system of claim 10 , comprising instructions to:

render a first arc fragment of the first loop upstream of an arc-shaped envelope with an arc-shaped channel with a first thickness that is selected to convey a mean pulmonary arterial pressure (MPAP) of the pulmonary circulation of the patient; and render a second arc fragment of the first loop downstream of the arc-shaped envelope with a second thickness that is selected to convey pulmonary artery occlusion pressure (PAOP) of the pulmonary circulation of the patient.

12 . The system of claim 10 , comprising instructions to:

render a first arc fragment of the second loop positioned upstream of an arc-shaped envelope with an arc-shaped channel with a third thickness that is selected to convey a mean arterial pressure (MAP) of the systemic circulation of the patient; and

render a second arc fragment of the second loop downstream of the arc-shaped envelope with a fourth thickness that is selected to convey central venous pressure (CVP) of the systemic circulation of the patient.
