Abstract

A system for providing continuous positive air pressure therapy is provided. The system includes a patient interface, a flow generator, a sensor, and a computing device. Wireless transceivers allow wireless communication between the computing device and the flow generator and/or patient interface. Sensor data is communicated to the computing device and a leak determination is made by the computing device based on the sensor data. If a leak is detected, then troubleshooting options for correcting the leak are displayed to the patient on a display of the computing device. The troubleshooting options may be selected based on the sensed data, the type of patient interface, the type of flow generator, or characteristics of the patient using the device.

First claim

The invention claimed is:

1. A system for providing continuous positive air pressure (CPAP) to a patient, the system comprising:
a flow generator configured to generate a supply of breathable gas that is delivered to the patient via a patient interface that is configured to engage with at least one airway of the patient, wherein the breathable gas is output from the flow generator at a pressure level that is above atmospheric pressure;
at least one sensor that is configured to measure a physical quantity while the breathable gas is supplied to the patient;
a first wireless communication transceiver that is electronically coupled to the patient interface or the flow generator; and
a computing device that includes at least a second wireless communications transceiver and at least one hardware processor, the at least one hardware processor configured to:
cause the pressure level supplied by the flow generator to increase from a first pressure level to a second pressure level,
receive, via a wireless transmission from the first wireless communication transceiver to the second wireless communications transceiver, first sensor data that is based on measured physical quantity of the at least one sensor,
perform, based on the received first sensor data and while the pressure level is controlled to increase to the second pressure level, a leak determination,
in response to leak detection by the leak determination:
display, to a display device that is coupled to the at least one hardware processor, a display screen that includes instructions for at least a first troubleshooting option that is selected to correct the leak detection, wherein the first troubleshooting option is selected based on a type identification of the flow generator and/or the patient interface, and
cause, via wireless communication, the flow generator to hold at a pressure level that is based on when the leak determination occurred,
after display of the instructions, acquire second sensor data that is based on another instance of the measured physical quantity,
perform, based on the received second sensor data, a subsequent leak determination, and
based on the subsequent leak determination that there is no leak, cause the pressure level increase to resume increasing to the second pressure level.

2. The system of claim 1 , wherein the at least one hardware processor is further configured to:
store a patient interface type for the patient interface or to store a flow generator type for the flow generator.

3. The system of claim 2 , wherein the at least one hardware processor is further configured to:
determine the patient interface type based on acquisition of an identifying feature of the patient interface; or
determine the flow generator type based on acquisition of an identifying feature of the flow generator.

4. The system of claim 1 , wherein the first troubleshooting option is among a plurality of troubleshooting options.

5. The system of claim 4 , wherein another troubleshooting option among the plurality of troubleshooting options is presented on the display device in response to subsequent leak detection at the subsequent leak determination.

6. The system of claim 1 , wherein the first troubleshooting option includes at least one of: repositioning the patient interface, checking straps of the patient interface, checking if the mouth of the patient is closed, checking connectors of the CPAP system, and taking off and putting the patient interface back on.

7. The system of claim 1 , wherein the at least one hardware processor is further configured to:
set, via wireless communication using the first and second wireless transceivers, the flow generator to the first pressure level, and
in response to reception of user input, cause, via wireless communication, the flow generator to increase the supply of breathable gas to the second pressure level.

8. The system of claim 1 , further comprising the patient interface.

9. The system of claim 1 , wherein the computing device includes a plurality of computing devices, with a first one of the plurality of computing devices communicates, via the second wireless communications transceiver, with the first wireless communication transceiver, and a second one of the plurality of computing devices communicates with the first one of the plurality of computing devices via a computer network.

10. The system of claim 9 , wherein the leak determination is performed by the second one of the plurality of computing devices.

11. The system of claim 1 , wherein the leak determination is automatically performed.

12. The system of claim 1 , wherein the leak determination is performed responsive to input provided to the computing device from a user.

13. The system of claim 1 , wherein the at least one hardware processor is further configured to, based on determination that no leak is present, cause the pressure level that is being supplied by the flow generator to be increased.

14. The system of claim 13 , wherein the pressure level is caused to be increased automatically.

15. The system of claim 1 , wherein the wireless transmission from the first wireless communication transceiver to the second wireless communications transceiver is Bluetooth.

16. A non-transitory computer readable storage medium storing instructions for use with a computing device that is configured to control a continuous positive air pressure (CPAP) device that is coupled to a first wireless communication transceiver, the CPAP device configured to generate a supply of breathable gas that is delivered to a patient via a patient interface, wherein the breathable gas is output from a flow generator at a pressure level that is above atmospheric pressure, the CPAP device associated with at least one sensor that is configured to measure a physical quantity while the breathable gas is supplied to the patient, the computing device including at least one hardware processor and a second wireless communication transceiver, the stored instructions comprising instructions that are configured to cause the computing device to:
receive, via a wireless transmission from the first wireless communication transceiver to the second wireless communications transceiver, first sensor data that is based on measured physical quantity of the at least one sensor;
cause the pressure level supplied by the flow generator to increase from a first pressure level to a second pressure level;
perform, based on the received first sensor data and while the pressure level is controlled to increase to the second pressure level, a leak determination;
based on leak detection by the leak determination:
cause the increase from the first pressure level to the second pressure level to hold at a level at which the leak detection was determined,
display, to a display device that is coupled to the computing device, a graphical interface that includes instructions for at least a first troubleshooting option to address the leak detection,
subsequent to output of the first troubleshooting option for display, acquire second sensor data that is based on another instance of the measured physical quantity from the at least one sensor, and
perform, based on the acquired second sensor data, a subsequent leak determination; and

based on the subsequent leak determination that there is no leak, cause the pressure level increase to resume increasing to the second pressure level.

17. The non-transitory computer readable storage medium of claim 16 , wherein the stored instructions comprise further instructions that are configured to cause the comput
