Abstract

According to various embodiments, methods and systems are provided herein for training a user in alarm behaviors of a medical device. The alarm behaviors may be accessed via a simulator system that obtains input regarding alarm settings, accesses stored plethysmographic waveform data representative of data obtained through the simulated medical device and that applies the alarm setting inputs to the stored plethysmographic waveform data to provide simulated alarm outputs representative of alarm outputs of the medical device.

Claims

1. A method comprising the steps of:

receiving an input related to an alarm setting;

accessing stored plethysmographic waveform data, wherein the stored plethysmographic waveform data is representative of data obtained by a medical device;

applying the alarm setting to the plethysmographic waveform data;

displaying a simulated output for the medical device based on the plethysmographic waveform data with the alarm setting applied; and

providing a simulated alarm output representative of an actual alarm output of the medical device based upon the alarm setting and the plethysmographic waveform data.

2. The method of claim 1, comprising displaying the plethysmographic waveform data comprises a trend view.

3. The method of claim 1, wherein the medical device comprises a pulse oximetry monitor.

4. The method of claim 1, comprising displaying information related to a clinical condition of a patient, wherein the stored plethysmographic waveform data is representative of data obtained from a patient with the clinical condition.

5. The method of claim 1, comprising receiving a second input related to a playback time for the displayed plethysmographic waveform data.

6. The method of claim 5, where the playback is representative of real-time.

7. The method of claim 1, comprising receiving a second input related to motion, arrhythmia, or a level of supplemental oxygen and applying the second input to the data.

8. The method of claim 1, wherein the simulated alarm output comprises a visual alarm indicator, an audible alarm indicator, or a combination thereof.

9. The method of claim 1, comprising:

receiving a second user input related to a second alarm setting;

applying the second alarm setting to the plethysmographic waveform data;

displaying a simulated output for the medical device based on the plethysmographic waveform data with the second alarm setting applied; and

providing a simulated alarm output representative of an actual alarm output of the medical device based upon the second alarm setting and the plethysmographic waveform data.

10. The method of claim 9, wherein the first alarm setting and the second alarm setting relate to the same alarm type.

11. The method of claim 10, wherein the first alarm setting and the second alarm setting relate to a saturation pattern detection alarm or an oxygen saturation limit alarm.

12. The method of claim 10, comprising displaying the simulated output for the medical device with the first alarm setting applied adjacent to the simulated output for the medical device with the second alarm setting applied.

13. The method of claim 9, wherein the first alarm setting and the second alarm setting relate to different alarm types.

14. The method of claim 13, wherein the first alarm setting relates to a saturation pattern detection alarm and the second alarm setting relates to an oxygen saturation limit alarm.

15. A system comprising:

a memory storing plethysmographic waveform data representative of data obtained by a medical device;

a processor configured to execute instructions for;

receiving an input related to an alarm setting from the alarm settings configuration menu;

accessing the stored plethysmographic waveform data from the memory;

applying the alarm setting to the plethysmographic waveform data using alarm algorithms employed in the medical device; and

providing a simulated alarm output representative of an actual alarm output of the medical device; and

a display configured to display the simulated alarm output.

16. The system of claim 15, wherein the processor is configured to receive a second input related to motion, arrhythmia, or a level of supplemental oxygen and to apply the input to the data.

17. The system of claim 15, wherein the processor is configured to provide clinical information based on the plethysmographic waveform data.

18. The system of claim 15, wherein the simulated alarm output comprises a graphical indicator.

19. The system of claim 18, wherein the graphical indicator comprises a triangular indicator that fills when the simulated alarm output comprises triggering events beyond a threshold.

20. A tangible, machine-readable medium having instructions encoded thereon for execution by a processor, comprising:

instructions for receiving an input related to an alarm setting;

instructions for accessing stored plethysmographic waveform data, wherein the stored plethysmographic waveform data is representative of data obtained by a medical device;

instructions for applying the alarm setting to the plethysmographic waveform data; and

instructions for displaying a simulated output for the medical device based on the plethysmographic waveform data with the alarm setting applied.
