Abstract

A user configurable variable mode pulse indicator provides a user the ability to influence outputs indicative of a pulse occurrence at least during distortion, or high-noise events. For example, when configured to provide or trigger pulse indication outputs, a pulse indicator designates the occurrence of each pulse in a pulse oximeter-derived photo-plethysmograph waveform, through waveform analysis or some statistical measure of the pulse rate, such as an averaged pulse rate. When the configured to block outputs or not trigger pulse indication outputs, a pulse indicator disables the output for one or more of an audio or visual pulse occurrence indication. The outputs can be used to initiate an audible tone “beep” or a visual pulse indication on a display, such as a vertical spike on a horizontal trace or a corresponding indication on a bar display. The amplitude output is used to indicate data integrity and corresponding confidence in the computed values of saturation and pulse rate. The amplitude output can vary a characteristic of the pulse indicator, such as beep volume or frequency or the height of the visual display spike.

Claims

1-8. -8. (canceled)

9. A method of configuring output indications of pulse occurrences in an patient monitor capable of monitoring a pulse rate through a signal from a noninvasive optical sensor, the method comprising:

receiving an input signal from said sensor;

determining a measure of distortion in said input signal; and

when said measure indicates a high level of distortion, outputting an indication of pulse occurrences according to user-selected configuration parameters.

10. The method of claim 9, wherein said indication comprises a pulse beep.

11. The method of claim 10, wherein said configuration parameters cause said pulse beep to be blocked.

12. The method of claim 10, wherein said configuration parameters cause said pulse beep to be responsive to a statistical representation of a calculated pulse rate.

13. The method of claim 9, wherein said indication comprises visual display elements.

14. The method of claim 13, wherein said configuration parameters cause at least one of said display elements to blocked.

15. The method of claim 13, wherein said configuration parameters cause at least one of said display elements to be responsive to a statistical representation of a calculated pulse rate.
