Abstract

Methods of measuring features of a digitally generated waveform include communicating patient data to a device that is remote from a source of the patient data, generating the waveform on a touch-screen display of the device, and measuring along an axis of the waveform. The measuring includes generating a first point corresponding to the waveform based on contact with the touch-screen display, generating a second point corresponding to the waveform based on contact with the touch-screen display, automatically measuring a distance between the first point and the second point along the axis upon generation of the second point, and displaying a value corresponding to the distance on the touch-screen display.

Claims

1. A method of measuring features of a digitally generated waveform, comprising:

communicating patient data to a device that is remote from a source of the patient data;

generating the waveform on a touch-screen display of the device; and

measuring along an axis of the waveform, the measuring comprising;

generating a first point corresponding to the waveform based on contact with the touch-screen display;

generating a second point corresponding to the waveform based on contact with the touch-screen display;

automatically measuring a distance between the first point and the second point along the axis upon generation of the second point; and

displaying a value corresponding to the distance on the touch-screen display.

2. The method of claim 1, wherein the value includes a time value.

3. The method of claim 1, wherein the value includes a voltage value.

4. The method of claim 1, further comprising generating a digital caliper in the touch-screen display, the caliper including a first and a second jaw that are movable along the axis, the first point being generated based on an intersection between the first jaw and the waveform, and the second point being generated based on an intersection between the second jaw and the waveform.

5. The method of claim 4, wherein the caliper is generated based on a user demand.

6. The method of claim 1, wherein the axis includes one of a time axis and a voltage axis.

7. The method of claim 1, wherein the waveform corresponds to one of an electrocardiogram (ECG), a blood pressure, an oxygen saturation, and an end-tidal CO.

8. The method of claim 1, further comprising:

moving at least one of the first point and the second point along the axis; and

updating the value in real-time based on movement of the at least one of the first point and the second point along the axis.

9. The method of claim 1, further comprising storing the value in a memory of the device.

10. The method of claim 1, further comprising transmitting the value to a patient information system located at a facility.

11. A method of monitoring patient data using a device, comprising:

communicating patient data to the device, the device being remote from a source of the patient data;

generating a waveform on a display of the device based on the patient data;

identifying an occurrence of a waveform feature; and

generating a sound based on the occurrence of the waveform feature.

12. The method of claim 11, wherein the generating a sound comprises repetitively generating the sound in response to periodic occurrences of the waveform feature.

13. The method of claim 11, wherein the generating a sound comprises generating a persistent sound.

14. The method of claim 11, further comprising:

storing an audio file in memory of the device; and

retrieving the audio file from memory based on generating the waveform, the sound being generated based on the audio file.

15. The method of claim 11, further comprising:

storing a plurality of audio files in memory of the device; and

selecting an audio file from the plurality of audio files based on a type of the waveform, the sound being generated based on the audio file.

16. The method of claim 11, wherein the waveform feature includes one of a spike, a peak, a trough and a flat line.

17. The method of claim 11, wherein the waveform corresponds to one of a heart rate, a blood pressure, an oxygen saturation, and an end-tidal CO₂.

18. A method of notifying a user of an alert, comprising:

generating an alert based on patient data;

providing the alert to a third-party notification service;

forwarding the alert to a device, the device being remote from a source of the patient data;

receiving the alert at the device; and

presenting an indication of the alert on a display of the device.

19. The method of claim 18, wherein the alert is generated at an information system that is resident at a facility, at which the patient data is collected.

20. The method of claim 18, wherein the alert is generated at a data management system that is remote from the source of the patient data.

21. The method of claim 18, wherein the alert corresponds to an application that is resident on the device, and that is executable using the device.

22. The method of claim 21, wherein the application is dormant when the alert is received at the device.

23. The method of claim 18, wherein the indication includes at least one of a badge associated with an application icon, and an alert summary.

24. The method of claim 23, wherein the alert summary provides patient information.

25. The method of claim 23, further comprising:

selecting the alert summary; and

displaying detailed alert information on the display of the device in response to the selecting.
