Abstract

A patient ventilation system including a ventilation interface and a ventilation source pneumatically coupled to a patient over the ventilation interface is disclosed. There is a controller that regulates airflow delivery from the ventilation source to the patient according to one or more predefined treatment configuration settings. The controller has an inactive ventilation state, a ventilation initiation state, a treatment state, a treatment suspension state, and a ventilation deactivation state. A display interface is coupled to the controller and configured to generate, exclusively, a device activation user element with the pressure controller in the inactive ventilation state, a fitment feedback indicator and a treatment screen in a ventilation initiation state, the fitment feedback indicator and a treatment status screen in the treatment state, a treatment suspension screen in the treatment suspension state, and a treatment conclusion screen in the ventilation deactivation state.

Claims

1. A patient ventilation system comprising:

a patient ventilation interface;

a ventilator device adapted to be pneumatically coupled to a patient over the patient ventilation interface;

a controller regulating airflow delivery from the ventilator device to the patient according to one or more predefined treatment configuration settings and having an inactive ventilation state entered upon powering on the patient ventilation system, a ventilation initiation state, a treatment state, a treatment suspension state, and a ventilation deactivation state;

an input interface coupled to the controller; and

a display interface coupled to the controller and configured to generate i) exclusively a device activation user element with the controller in the inactive ventilation state, ii) exclusively a patient ventilation interface fitment feedback indicator and a treatment screen with the controller in the ventilation initiation state, iii) exclusively the patient ventilation interface fitment feedback indicator and a treatment status screen with the controller in the treatment state concurrently with the ventilator device delivering the airflow to the patient over a predefined ramp characterized by a ramp pressure and a ramp time according to the treatment configuration settings defined from the treatment screen, iv) exclusively a treatment suspension screen with the controller in the treatment suspension state and the controller suspending the gas flow to the patient, and v) exclusively a treatment conclusion screen with the controller in the ventilation deactivation state and the controller stopping the ventilator device from delivering gas flow to the patient.

2. The system of claim 1, wherein the controller transitions from the inactive ventilation state to the ventilation initiation state in response to one of a user input detected on the input interface corresponding to a selection of the device activation user element and a detected activation of the ventilator device.

3. The system of claim 2, wherein the device activation user element is displayed substantially dominantly on the display interface.

4. The system of claim 1, wherein the treatment screen includes one or more modifiable user interface elements each showing predefined values and corresponding to the one or more treatment configuration settings.

5. The system of claim 4, wherein the one or more treatment configuration settings is a ramp pressure setting.

6. The system of claim 4, wherein the one or more treatment configuration settings is a ramp time setting.

7. The system of claim 4, wherein the one or more treatment configuration settings is a treatment duration time.

8. The system of claim 1, wherein the controller transitions from the ventilation initiation state to the treatment state in response to one of an input received on the input interface corresponding to a selection of a treatment continuation user element and an expiration of a time out period.

9. The system of claim 1, wherein the treatment conclusion screen includes a set of usage statistics data and a preselected patient motivational message corresponding to specific values of the set of usage statistics data.

10. The system of claim 9, wherein the set of usage statistics data includes a total usage duration.

11. The system of claim 9, wherein the set of usage statistics data includes a ventilation source activation duration.

12. The system of claim 9, wherein the set of usage statistics data includes a patient ventilation interface fitment feedback indicator average.

13. The system of claim 1, wherein the controller transitions from the treatment state to the ventilation deactivation state in response to at least one of an input received on the input interface corresponding to a selection of the treatment termination user element and a deactivation of the ventilator device.

14. The system of claim 1, wherein the input interface is a touch screen overlaid on the display interface, input received on the input interface spatially corresponding to a display position of the device activation user element.

15. The system of claim 1, wherein the device activation user element is rendered prominently over any other elements simultaneously displayed on the display interface.

16. The system of claim 1 wherein the device activation user element is the sole element displayed on the display interface at a given instance.

17. The system of claim 1, wherein the patient ventilation interface fitment feedback indicator includes a suggested corrective adjustment.

18. The system of claim 1, wherein the treatment status screen includes a clock display.

19. The system of claim 1, wherein the treatment status screen includes an elapsed time display.

20. The system of claim 19, wherein the elapsed time display is a countdown timer.

21. The system of claim 1, wherein the treatment status screen includes a ventilation delivery pressure indicator.

22. The system of claim 1, wherein the treatment status screen includes a ramping countdown timer display.

23. The system of claim 1, wherein the controller transitions from the treatment state to the treatment suspension state in response to a detection of either one or both of an input received on the input interface corresponding to a selection of a treatment suspension user element or a modification to a pneumatic circuit between the patient and the ventilator device.

24. The system of claim 23, wherein the first modification to the pneumatic circuit between the patient and the ventilator device is a disconnection of the patient ventilation interface from the patient.

25. The system of claim 23, wherein the first modification to the pneumatic circuit between the patient and the ventilator device is an introduction of an occlusion in the pneumatic circuit.

26. The system of claim 1, wherein the patient ventilation interface fitment feedback indicator includes a graphical illustration indicative of the fit of the patient ventilation interface.

27. A patient ventilation system comprising:

a patient ventilation interface;

a ventilator device adapted to be pneumatically coupled to a patient over the patient ventilation interface;
