## Abstract

A method for testing lung function of a user donning a user interface includes administering a supplemental breathing test in response to receiving an input from the user selecting the supplemental breathing test. The user interface is coupled, via a conduit, to a respiratory therapy device in a respiratory therapy system. Moreover, the supplemental breathing test is administered by adjusting parameters of the respiratory therapy device. The method also includes receiving first airflow parameter data associated with a first airflow generated by the user. The first airflow is generated by the user into an interior of the user interface while donning the user interface. The method also includes characterizing the lung function of the user based at least in part on the first airflow parameter data.

## Claims

### Claim at position 1

1-35. (canceled)

### Claim 36

A respiratory therapy system comprising:
a respiratory therapy device;
a conduit;
a user interface, the user interface being coupled, via the conduit, to the respiratory therapy device;
a memory device having stored thereon machine-readable instructions; and
a control system including one or more processors configured to execute the machine-readable instructions to:
in response to receiving an input from the user selecting a supplemental breathing test, administering the supplemental breathing test by adjusting parameters of the respiratory therapy device;
receiving first airflow parameter data associated with a first airflow generated by the user into an interior of the user interface while donning the user interface; and
characterizing the lung function of the user based at least in part on the first airflow parameter data.

### Claim 37 (depends on 36)

The respiratory therapy system of claim 36, wherein administering the supplemental breathing test includes generating a second airflow from the respiratory therapy device to the conduit by operating a motor of the respiratory therapy device at one or more discrete operating speeds.

### Claim 38 (depends on 37)

The respiratory therapy system of claim 37, wherein the received first airflow parameter data includes useable data collected at each of the one or more discrete operating speeds of the motor.

### Claim 39 (depends on 37)

The respiratory therapy system of claim 37, wherein the second airflow causes a predetermined air pressure in the interior of the user interface, the predetermined air pressure corresponding to the supplemental breathing test.

### Claim 40 (depends on 39)

The respiratory therapy system of claim 39, wherein the second airflow is generated in response to receiving an acknowledgement from the user.

### Claim 41 (depends on 37)

The respiratory therapy system of claim 37 wherein administering the supplemental breathing test includes providing instructions to the user that correspond to the supplemental breathing test, wherein the second airflow is generated in parallel with the instructions provided to the user.

### Claim 42 (depends on 41)

The respiratory therapy system of claim 41, wherein providing the instructions to the user includes displaying the instructions on a display of the respiratory therapy device.

### Claim 43 (depends on 42)
