Abstract

An apparatus and associated method for collecting data for a sleep study. The apparatus includes a sensor adapted to collect data relating to a parameter of a user of the apparatus over a period of time, and a controller operatively coupled to the sensor. The controller is adapted to: (a) receive configuration information specifying a predetermined amount of valid data that is required for a sleep study to be deemed valid, (b) receive the data relating to the parameter and determine an amount of the received data that is valid, and (c) cause a study status indicator to be output by the apparatus based on the amount of the received data that is determined to be valid and the predetermined amount specified in the configuration information.

Claims

1. An apparatus for collecting data for a sleep study, comprising:

a sensor adapted to collect data relating to a parameter of a user of the apparatus over a period of time; and

a controller operatively coupled to the sensor, the controller being adapted to;

(a) receive configuration information specifying a predetermined amount of valid data that is required for a sleep study to be deemed valid, (b) receive the data relating to the parameter and determine an amount of the received data that is valid, and (c) cause a study status indicator to be output by the apparatus based on the amount of the received data that is determined to be valid and the predetermined amount specified in the configuration information.

2. The apparatus according to claim 1, wherein the study status indicator is representative of a percentage based on the amount of the received data that is determined to be valid as compared to the predetermined amount specified in the configuration information.

3. The apparatus according to claim 2, wherein the study status indicator is a visual indicator.

4. The apparatus according to claim 3, wherein the visual indicator comprises a plurality of sections, wherein at least one section in the plurality of sections is visually distinguished from a remainder of the plurality of sections based on the percentage.

5. The apparatus according to claim 1, wherein the sensor comprises:

a flow sensor adapted to collect flow data relating to a flow of gas breathed in and out by the user; and

further comprising an oximetry sensor adapted to collect oximetry data relating to an oxygen saturation of the user, the data relating to the parameter comprising the flow data and the oximetry data, wherein the controller is adapted to determine an amount of the received data that is valid by determining an accumulated time during which the flow data and the oximetry data are simultaneously valid.

6. The apparatus according to claim 5, wherein the status indicator is representative of a percentage based on the amount of the received data that is determined to be valid as compared to the predetermined amount specified in the configuration information.

7. The apparatus according to claim 6, wherein the status indicator is a visual indicator.

8. The apparatus according to claim 7, wherein the visual indicator comprises a plurality of sections, wherein at least one section in the plurality of sections is visually distinguished from a remainder of the plurality of sections based on the percentage.

9. The apparatus according to claim 5, wherein the oximetry sensor comprises an SpO2 probe.

10. The apparatus according to claim 5, wherein the flow sensor comprises:

a temperature sensor adapted to collect the flow data based on a temperature of the gas breathed in and out by the user;

a pressure transducer adapted to collect the flow data based on pressure variations of the gas breathed in and out by the user;

or

both the temperature sensor and the pressure transducer.

11. The apparatus according to claim 5, wherein the flow data is deemed to be valid responsive to a peak-to-peak change in the flow data exceeding a predetermined threshold.

12. The apparatus according to claim 5, wherein portions of the flow data and the oximetry data are deemed to be simultaneously valid during time periods where both the flow data and the oximetry data are valid for at least a predetermined amount of time.

13. The apparatus according to claim 12, wherein the predetermined amount of time is at least one minute.

14. A method of collecting data for a sleep study, comprising:

receiving configuration information specifying a predetermined amount of valid data that is required for a sleep study to be deemed valid;

collecting data relating to a parameter of a patient over a period of time;

determining an amount of the collected data that is valid;

storing at least the collected data that is determined to be valid; and

providing a study status indicator based on the amount of the collected data that is determined to be valid and the predetermined amount specified in the configuration information.

15. The method according to claim 14, wherein the study status indicator is representative of a percentage based on the amount of the collected data that is determined to be valid as compared to the predetermined amount specified in the configuration information.

16. The method according to claim 15, wherein the study status indicator is a visual indicator.

17. The method according to claim 16, wherein the visual indicator comprises a plurality of sections, wherein at least one section in the plurality of sections is visually distinguished from a remainder of the plurality of sections based on the percentage.

18. The method according to claim 14, wherein the collecting data relating to the parameter comprises:

collecting flow data relating to a flow of gas breathed in and out by the user; and

collecting oximetry data relating to an oxygen saturation of the user, the data relating to the parameter comprising the flow data and the oximetry data, and wherein the determining an amount of the collected data that is valid comprises determining an accumulated time during which the flow data and the oximetry data are simultaneously valid.

19. The method according to claim 18, wherein the study status indicator is representative of a percentage based on the amount of the collected data that is determined to be valid as compared to the predetermined amount specified in the configuration information.

20. The method according to claim 19, wherein the study status indicator is a visual indicator.

21. The method according to claim 20, wherein the visual indicator comprises a plurality of sections, wherein at least one section in the plurality of sections is visually distinguished from a remainder of the plurality of sections based on the percentage.

22. The method according to claim 18, wherein the flow data is deemed to be valid responsive to peak-to-peak changes in the flow data exceeding a predetermined threshold.

23. The method according to claim 18, wherein portions of the flow data and the oximetry data are deemed to be simultaneously valid during time periods where both the flow data and the oximetry data are valid for at least a predetermined amount of time.

24. The method according to claim 23, wherein the predetermined amount of time is at least one minute.

25. The method according to claim 14, wherein the receiving, collecting, determining, storing, and providing steps are performed using an apparatus having one or more sensors for collecting the data relating to the parameter, and wherein the receiving, collecting, determining, storing, and providing steps are repeated one or more times using the apparatus.
