Abstract

A method of receiving data indicative of at least one physiological parameter of a patient, receiving image data of the patient, determining that a value of the at least one physiological parameters signifies an alarm condition in the patient, generating an alarm data set including image or audio data of the patient and the value of at least one physiological parameter, and transmitting a notification of the alarm condition including the alarm data set to a clinician.

Claims

1. A method comprising:

receiving data indicative of at least one physiological parameter of a patient;

receiving image data of the patient;

analyzing and processing, by an application server, the image data of the patient to determine if the patient has moved;

determining that a value of the at least one physiological parameters signifies an alarm condition of the patient;

generating an alarm data set including image or audio data of the patient and the value of at least one physiological parameter when determined that the value of the at least one physiological parameter signifies an alarm condition of the patient; and

transmitting a notification of the alarm condition including the alarm data set to a clinician.

2. The method of claim 1, wherein the image data includes video data of a patient before and after the occurrence of the alarming condition.

3. The method of claim 1, further comprising determining whether the at least one physiological parameter signifying an alarm condition is a movement volatile parameter.

4. The method of claim 3, further comprising determining whether the image data indicates movement of the patient at the occurrence of the alarm condition.

5. The method of claim 4, further comprising generating an automatic recommendation for responding to the transmitted notification of the alarm condition when determined that the at least one physiological parameter is movement volatile and that the patient moved.

6. The method of claim 1, further comprising transmitting a notification of the alarm condition to a remote device.

7. The method of claim 6, further comprising receiving input data that addresses the notification from the remote device.

8. The method of claim 6, further comprising displaying the image data of the alarm data set on the remote device.

9. The method of claim 6, further comprising receiving a request for additional data related to the notification.

10. The method of claim 1, wherein the at least one physiological parameter of the patient whose value is determined to signify an alarm condition is comprised of two physiological parameters which individually signify no alarm condition.

11. The method of claim 1, further comprising analyzing image data of the alarm data set to determine whether movement of the patient was a factor in causing the at least one physiological parameter to signify an alarm condition.

12. A remote device for analyzing patient data comprising:

a transmit/receiver connecting the remote device to a data source;

an application server processing data received from or transmitted to the data source, the data including patient data from one or more medical devices monitoring at least one physiological parameter of a patient and image data of the patient; and

a display on which visual representations of the at least one physiological parameter can be viewed, the display including the image data or audio data of the patient and a volatility module, wherein the application server is configured to analyze the image data to determine if the patient has moved and wherein the volatility module is configured to identify instances of historical patient data where a value of one or more patient data points experienced a medically significant change.

13. The remote device of claim 12, further comprising a scroll bar allowing a clinician to scroll from one indicator to the next on the volatility module.

14. The remote device of claim 12, wherein the display depicts a historical graph of at least one physiological parameter among the patient data.

15. The remote device of claim 12, wherein user inputs to the remote device are transmitted to the data source and stored as part of the patient data.

16. The remote device of claim 12, wherein a notification alarm condition in the patient received from the data source can be analyzed and responded to by a clinician.

17. A non-transitory computer readable recording medium, storing a computer program, which, when executed by a computer, causes a computer to perform a method comprising:

receiving at an application server data indicative of at least one physiological parameter of a patient and image data of the patient;

determining by the application server that a value of the at least one physiological parameters signifies an alarm condition in the patient;

generating an alarm data set including image or audio data of the patient and the value of the at least one physiological parameter;

transmitting an alarm notification of the alarm condition including the alarm data set to a web server for publication on a web-page, the web-page being accessible by one or more remote devices for clinical analysis of the alarm data set.

18. The non-transitory computer readable recording medium of claim 17, wherein data input from a remote device regarding the alarm notification is received by the application server and included as part of the alarm data set.

19. The non-transitory computer readable recording medium of claim 17, wherein the image data includes video data from before and after the determination of an alarm condition.

20. The non-transitory computer readable recording medium of claim 17, wherein the alarm data set includes an indication that movement by the patient is a factor in causing physiological parameters to signify an alarm condition.
