Abstract

A patient monitoring system can display one or more configurable health monitors on a configurable user interface. The health indicators are configured to display a physiological signal from a patient. The patient monitoring system can calculate ranges of values for the health indicator that correspond to a status of the patient. The health indicators can display different outputs based on the value of the physiological signal.

Claims

1. A patient monitoring system, comprising:

at least one physiological sensor including a first and second light emitter and a detector, wherein the physiological sensor is configured to measure at least one physiological signal from a patient;

at least one health indicator, wherein the health indicator is configured to display a signal value based upon the at least one physiological signal;

a processor;

receive patient information;

calculate a first range of values for the at least one health indicator based at least in part on the patient information, wherein the first range of values corresponds to a first range of physiological signals from the patient, wherein the first range of values corresponds to a first patient condition;

calculate a second range of values for the at least one health indicator based at least in part on the patient information, wherein the second range of values corresponds to a second range of physiological signals from the patient, wherein the second range of values corresponds to an second patient condition; and

wherein the at least one health indicator is configured to display a first output when the signal value is within the first range of values; and

wherein the at least one health indicator is configured to display a second output when the signal value is within the second range of values.

2. The patient monitoring system of claim 1, wherein the first patient condition is a healthy condition.

3. The patient monitoring system of claim 1, wherein the first patient condition is an unhealthy condition.

4. The patient monitoring system of claim 1, wherein the patient monitoring system is further configured to calculate a third range of values for the health indicator, wherein the third range of values corresponds to a third range of physiological signals from the patient, wherein the third range of values corresponds to an intermediate patient condition;

5. The patient monitoring system of claim 4, wherein the first range of values, the second range of values, and the third range of values do not overlap.

6. The patient monitoring system of claim 1, wherein the first health indicator is configured to output an alarm signal when the signal value moves from the first range of values to the second range of values.

7. The patient monitoring system of claim 6, wherein the alarm signal is an audible alarm

8. The patient monitoring system of claim 1, wherein the first output is a first color displayed on the health indicator and the second output is a second color displayed on the health indicator.

9. The patient monitoring system of claim 1, wherein the first output and the second output are both displayed when the signal value is in the second range of values.

10. The patient monitoring system of claim 1, wherein the patient monitoring system is configured to communicate the signal value with a mobile device.

11. The patient monitoring system of claim 1, wherein the patient information is at least one of age, gender, height, or weight.

12. The patient monitoring system of claim 1, wherein the patient information is information associated with the medical history of the patient.

13. The patient monitoring system of claim 1, wherein the health indicator is a circular health indicator.

14. The patient monitoring system of claim 1, wherein the health indicator is a vertical bar indicator.

15. The patient monitoring system of claim 1, wherein the health indicator is a trend graph indicator.

16. The patient monitoring system of claim 15, wherein the health indicator is a wherein the signal value is a point on a trend graph.

17. The patient monitoring system of claim 1, wherein the signal value is a numeric value.

18. The patient monitoring system of claim 1, wherein the signal value is an analog indicator.

19. The patient monitoring system of claim 1, wherein the at least one physiological sensor is configured to measure glucose, blood pressure, pulse rate, respiration rate, oxygen saturation, total hemoglobin, carboxyhemoglobin, methemoglobin, perfusion index, or temperature.

20. The patient monitoring system of claim 1, wherein the physiological sensor is a pulse oximeter.

21. A method of monitoring a patient, comprising;

receiving patient information;

calculating a first range of values for the health indicator, wherein the first range of values corresponds to a first range of physiological signals from the patient, wherein the first range of values corresponds to a healthy patient condition;

calculating a second range of values for the health indicator, wherein the second range of values corresponds to a second range of physiological signals from the patient;

wherein the second range of values corresponds to a an unhealthy patient condition; and

measuring at least one physiological signal from a patient using a physiological sensor having a first and second light emitter and a detector;

displaying the signal value on the first health indicator;

displaying a first output on the health indicator when the first value is within the first range of values; and

displaying a second output on the health indicator when the second value is within the second range of values.

22. The method of claim 21, further comprising the step of displaying a threshold indicator separating the first range of values from the second range of values.

23. The method of claim 21, wherein the physiological sensor is configured to measure glucose, blood pressure, pulse rate, respiration rate, oxygen saturation, total hemoglobin, carboxyhemoglobin, methemoglobin, perfusion index, or temperature.

24. The patient monitoring system of claim 21, wherein the patient information is at least one of age, gender, height, or weight.
