Abstract

Embodiments are disclosed that enable an electronic device to instruct as user how to user one or more noninvasive sensors to measure one or more physiological parameters of a patient. In one embodiment, the measured parameters are used to obtain a diagnosis, such as a diagnosis of a critical congenital heart defect.

Claims

1. (canceled)

2. A system for noninvasively measuring a physiological parameter of a patient to facilitate a diagnosis, the system comprising:

an electronic device comprising a display, a wireless transceiver, a memory device comprising processor-executable instruction stored thereon, and a hardware processor in communication with the display, wireless transceiver, and the memory;

the hardware processor programmed to execute the processor-executable instructions stored in the memory so as to;

display, on the display, instructions to obtain a first measurement by positioning a first noninvasive sensor at a first measurement site on a patient;

receive, from the noninvasive sensor, first signals responsive to a first physiological characteristic of the patient;

calculate a first measured physiological parameter responsive to the first signals;

display, on the display, instructions to obtain a second measurement by positioning a second noninvasive sensor at a second measurement site on the patient;

receive, from the second noninvasive sensor, second signals responsive to a second physiological characteristic of the patient;

calculate a second measured physiological parameter of the patient responsive to the second signals;

display, on the display, the first and second measured physiological parameters;

transmit, with the wireless transceiver, the first and second measured parameters over a network to a clinician; and

initiate, with the wireless transceiver, a telemedicine session with the clinician over the network to obtain a diagnosis based on the first and second measured parameters.

3. The system of claim 2, wherein the first measured parameter is oxygen saturation and the second measured parameter is blood pressure.

4. The system of claim 2, wherein the wireless transceiver is configured to receive an instruction to re-run one or both of the first and second measurements.

5. The system of claim 2, wherein the hardware processor is further configured to output a selection of clinicians, receive a selection of one of the clinicians from the patient, and initiate a communication session with the clinician.

6. The system of claim 2, wherein the telemedicine session comprises a video of the clinician.

7. The system of claim 2, wherein the hardware processor is further configured to receive an indication of a prescription.

8. The system of claim 2, wherein the hardware processor is further configured to instruct the patient to take a temperature reading.

9. The system of claim 2, wherein the hardware processor is further configured to instruct the patient to perform the first measurement again due to low signal confidence in the first measurement.

10. A system for noninvasively measuring a physiological parameter of a patient to facilitate a diagnosis, the system comprising:

an electronic device in communication with a noninvasive sensor coupled with a patient, the electronic device configured to drive light sources of the noninvasive sensor and to receive output signals from the noninvasive sensor, said electronic device comprising a hardware processor configured to;

process the output signals from the noninvasive sensor to measure a physiological parameter associated with the patient;

determine, based on a level of the physiological parameter, that critical congenital heart defect (CCHD) screening is recommended;

transmit a notification that the CCHD screening is recommended; and

subsequent to said transmission of the notification, and in response to receipt of an indication that CCHD screening is to be performed;

display, on a display of the electronic device, instructions to position the noninvasive sensor at a first measurement site on the patient;

obtain, with the noninvasive sensor, first physiological data from the first measurement site;

15. The system of claim 14, wherein the hardware processor is further configured to output an indication that the first and second selected physiological parameter values were selected to calculate the difference due to the first and second selected physiological parameter values having the highest values of the first and second confidence values.
