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.

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 CO2.

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

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

10. The method of claim 1, further comprising:

identifying an occurrence of a waveform feature; and

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

11. The method of claim 10, wherein the generating a sound comprises repetitively generating the sound in response to periodic occurrences of the waveform feature.

12. The method of claim 10, wherein the generating a sound comprises generating a persistent sound.

13. The method of claim 10, further comprising:

storing an audio file in memory of the handheld device; and

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

14. The method of claim 10, further comprising:

storing a plurality of audio files in memory of the handheld 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.

15. The method of claim 10, wherein the waveform feature includes one of a spike, a peak, a trough and a flat line.

16. The method of claim 10, wherein the waveform corresponds to one of a heart rate, a blood pressure, an oxygen saturation, and an end-tidal CO2.

17. The method of claim 1, further, comprising:

generating an alert based on the patient data;
