Abstract

A system is provided for creating a sound profile that matches sounds produced by a patient during a physical examination, such as a cardiac or pulmonary examination. A user selects multiple sounds from a library and combines them to form the profile which may then be modified by the addition of further sounds, adjustments to their relative timing, duration, loudness, and so forth. The refinement continues iteratively, and after each change the profile is provided by the system to the user, for example, as a phonocardiogram for comparison against the sounds observed during the examination.

Claims

1. A method comprising:

selecting, using an input device of a computing system, a first bodily sound component from a menu of sound components;

selecting, using the input device, a second bodily sound component from the menu of sound components, the first and second bodily sound components being representative of first and second sounds of a stethoscopic examination;

observing on a display of the computing system, and listening to, a repeating graphical representation of the first and second sound components; and

simulating an abnormality by iteratively modifying and observing the graphical representation.

2. The method of claim 1 wherein the first bodily sound component is a first lung sound component and wherein the second bodily sound component is a second lung sound component.

3. The method of claim 2 wherein selecting the first and second bodily sound components from the menu of sound components comprises selecting a respiratory pattern from a menu of respiratory patterns.

4. The method of claim 1 wherein the graphical representation of the first and second sound components comprises a phonocardiogram.

5. The method of claim 1 wherein modifying the graphical representation comprises selecting a third sound.

6. The method of claim 1 wherein modifying the graphical representation comprises changing a relative timing of the first and second sounds.

7. The method of claim 1 further comprising an act of reading a list, the list including the names of differential diagnoses, the list being read from the display of the computing system.

8. The method of claim 4 further comprising viewing on the display of the computing system an ECG proximate to the graphical representation of the first and second sound components.

9. The method of claim 1 wherein listening to the repeating graphical representation of the first and second sound components includes hearing the first and second sound components spatially separated from one another.

10. The method of claim 4 wherein the first and second sounds are heart sounds S1 and S2.

11. The method of claim 1 further comprising physically examining a patient, wherein the first and second sound components are selected to be representative of first and second sounds heard during a stethoscopic examination of the patient.

12. The method of claim 11 further comprising uploading, from the computing system, findings from the physical examination to an electronic health record for the patient.
