Abstract

A method includes obtaining an electrical signal that includes a set of at least two sensed physiologic measurements of a patient, comparing the at least two physiologic measurements with a predetermined physiologic measurement range, identifying data required to determine a probability and a severity of a condition of interest of the patient, in response to determining the at least two physiologic measurements do not satisfy the physiologic measurement range, receiving the identified data in electronic format, determining a first probability and a first severity of the condition of interest based on the received identified data, determining a recommended course of action for the patient based on the first probability and the first severity, resources of a healthcare facility, and an event guideline; and causing a display to visually present the first probability and first severity and the recommended course of action.

Claims

receiving an electrical signal that includes a set of at least two sensed physiologic measurements of a patient;

comparing the at least two physiologic measurements with a predetermined physiologic measurement range from a sensor output guideline, which is in electronic format;

identifying an ultrasound imaging procedure for acquiring data to determine a probability and a severity of a condition of interest of the patient based on a data guideline, in response to determining the at least two physiologic measurements do not satisfy the physiologic measurement range;

obtaining image data from a scan based on the identified ultrasound imaging procedure;

determining the probability and the severity of the condition of interest based on the obtained image data;

determining a recommended course of action for the patient based on the probability and the severity, resources of a healthcare facility, and an event guideline; and

causing a display to visually present the probability and severity and the recommended course of action.

2. The method of claim 1, further comprising:

generating a control signal that controls an operation of an electronic device associated with healthcare for the patient based on the recommended course of action and the event guideline; and

controlling the operation of the electronic device with the control signal.

3. The method of claim 1, further comprising:

receiving an image atlas of organ defects, wherein the determining the probability and the severity of the condition of interest based on the obtained image data includes determining the probability and the severity of the condition of interest based on the image data and the image atlas of organ defects.

4. The method of claim 1, further comprising:

identifying other data likely to improve an accuracy of the probability and the severity of the condition of interest; and

updating the probability and the severity, based on the other data to generate an updated probability and an updated severity of the condition of interest;

wherein the recommended course of action is determined based on the updated probability and the updated severity, the resources of the healthcare facility, and the event guideline.

5. The method of claim 1, wherein the condition of interest is a congenital cardiac defect of a newborn and the at least two sensed physiologic measurements include a blood oxygen concentration sensed at a right foot of the newborn and a blood oxygen concentration sensed at a left hand of the newborn.

6. The method of claim 5, wherein comparing the at least two physiologic measurements includes taking a difference between the at least two physiologic measurements and determining a difference blood oxygen concentration value, comparing the difference blood oxygen concentration value with the measurement range from the sensor output guideline, and determining blood is being shunted around the lungs.

7. A computing system comprising:

at least one computer processor; and

a computer readable storage medium encoded with a triage module wherein the at least one computer processor is configured to execute instructions of the triage module to perform operations including;

receiving an electrical signal that includes a set of at least two sensed physiologic measurements of a patient;

comparing the at least two physiologic measurements with a predetermined physiologic measurement range from a sensor output guideline, which is in electronic format;

identifying an ultrasound imaging procedure for acquiring data to determine a probability and a severity of a condition of interest of the patient based on a data guideline, in response to determining the at least two physiologic measurements do not satisfy the physiologic measurement range;

11. The system of claim 7, wherein the recommended course of action includes transporting the patient to another healthcare facility better equipped for the condition of interest.

12. The system of claim 11, wherein the recommended course of action further includes suggested healthcare to mitigate worsening of the condition of interest before the patient is transported.

13. The system of claim 7, wherein the recommended course of action includes suggested healthcare to mitigate worsening of the condition of interest at the healthcare facility using the resources available at the healthcare facility.

14. A non-transitory computer readable storage medium encoded with computer readable instructions, which, when executed by a processer, cause the processor to:
