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 respiratory therapy device that is 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;
at least one sensor that is configured to measure a physical quantity while the breathable gas is supplied to the patient;
a transceiver; and
a non-transitory computer readable storage medium storing computer instructions for use with a computing device that is configured to electronically communicate with the transceiver, the computer instructions comprising instructions that, when executed by at least one hardware processor of the computing device, cause the at least one hardware processor to perform operations comprising:
communicating a command to the respiratory therapy device, the command configured to set a target pressure level for which the pressure of the supply of breathable gas is to be provided;
processing first sensor data that is based on a measured physical quantity of the at least one sensor;
obtaining, based on the first sensor data, a leak determination;
based on detection of a leak, using the first sensor data, by the leak determination:
(a) outputting, to a display device associated with the computing device, a display screen that includes instructions for at least a first troubleshooting option that is selected to correct the leak, and
(b) communicating, to the respiratory therapy device, a command to hold at the pressure of the supply of breathable gas at a held pressure level that is different from the target pressure level,

after communication of the command to hold the pressure at the held pressure level, processing second sensor data that is based on another instance of the measured physical quantity of the at least one sensor;
obtaining, based on the second sensor data, another leak determination; and
based on the another leak determination that there is no leak, communicating, to the respiratory therapy device, a further command to cause the pressure of the supply of breathable gas to resume increasing towards the target pressure level.

2. The system of claim 1 , wherein the measured physical quantity includes pressure or flow data.

3. The system of claim 1 , wherein the operations further comprise:
transmitting a message, which is based on the first sensor data, to an external computing device to obtain the leak determination.

4. The system of claim 3 , further comprising:
the external computing device that includes a second hardware processor, the external computing device comprising instructions that, when executed by the second hardware processor, cause the second hardware processor to perform operations comprising:
generating the leak determination; and
communicating a responsive message back to the computing device, the responsive message including the leak determination.

5. The system of claim 1 , wherein the held pressure level is a pressure that is based on when the leak was detected.

6. The system of claim 1 , wherein the first troubleshooting option is based on which type, of multiple different possible types, of respiratory therapy device and/or patient interface is being used to deliver the supply of breathable gas to the at least one airway of the patient.

7. The system of claim 6 , wherein the operations further comprise:
acquiring a patient interface type for the patient interface that is being used; and
acquiring a respiratory therapy device type for the respiratory therapy device that is being used.

8. The system of claim 7 , wherein the operations further comprise:
determine the patient interface type based on acquisition of an identifying feature of the patient interface; or
determine the respiratory therapy device type based on acquisition of an identifying feature of the respiratory therapy device.

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

10. The system of claim 9 , wherein another troubleshooting option is among the plurality of troubleshooting options,
wherein the operations further comprise:
obtaining, subsequent to the leak determination and prior to the another leak determination, a third leak determination; and
based on detection of a leak at the third leak determination, outputting to the display device that is associated with the computing device, the another troubleshooting option, which is different from the first troubleshooting option, that is selected to correct the leak.

11. The system of claim 1 , wherein the leak determination is performed in response to reception of manual input provided to the computing device by a user.

12. The system of claim 11 , wherein the further command is communicated in response to manual input provided by the user to the computing device.

13. A non-transitory computer readable storage medium storing instructions for use with a computing device, which includes at least one hardware processor, that is configured to communicate with a respiratory therapy device of a continuous positive air pressure (CPAP) system, the respiratory therapy device configured to generate a supply of breathable gas that is delivered to a patient via a patient interface that is configured to engage with at least one airway of the patient, the CPAP system including at least one sensor that is configured to measure a physical quantity while the breathable gas is supplied to the patient, the stored instructions comprising instructions that are configured to cause the at least one hardware processor to perform operations comprising:
communicating a command to the respiratory therapy device, the command configured to set a target pressure level for which the pressure of the supply of breathable gas is to be provided;
processing first sensor data that is based on a measured physical quantity of the at least one sensor;
obtaining, based on the first sensor data, a leak determination;
based on detection of a leak, using the first sensor data, by the leak determination:
(a) outputting, to a display device associated with the computing device, a display screen that includes instructions for at least a first troubleshooting option that is selected to correct the leak, and
(b) communicating, to the respiratory therapy device, a command to hold at the pressure of the supply of breathable gas at a held pressure level that is different from the target pressure level,

after communication of the command to hold the pressure at the held pressure level, processing second sensor data that is based on another instance of the measured physical quantity of the at least one sensor;
obtaining, based on the second sensor data, another leak determination; and
based on the another leak determination that there is no leak, communicating, to the respiratory therapy device, a further command to cause the pressure of the supply of breathable gas to resume increasing towards the target pressure level.

14. The non-transitory computer readable storage medium of claim 13 , wherein the measured physical quantity includes pressure or flow data.

15. The non-transitory computer readable storage medium of claim 13 wherein the operations further comprise:
transmitting a message, which is based on the first sensor data, to an external computing device to obtain the leak determination.

16. The non-transitory computer readable storage medium of claim 13 , wherein the held pressure level is a pressure that is base
