Abstract

A respiratory humidification system includes a humidifier that is capable of electronic communication with one or more other components of the system thereby permitting transfer of data or control signals between the humidifier and other components of the system. In some systems, a flow generator, such as a ventilator, is provided to supply a flow of breathing gas. The humidifier and the flow generator are capable of electronic communication with one another. In some arrangements, an operating mode or parameter of the humidifier to be set or confirmed by the flow generator, either automatically or manually through a user interface of the flow generator. The humidifier can also utilize data provided by the flow generator or other system component, such as an incubator, to set or confirm an operating mode or parameter of the humidifier. In some arrangements, a user interface of the humidifier can display data from another system component, such as a nebulizer or pulse oximeter.

First claim

What is claimed is:

1. A humidification system comprising:
a humidifier configured to receive a flow of gas from a flow generator and to output a humidified flow of gas, the humidifier comprising a first controller; and
a communication connection configured to communicably couple the humidifier to one of a plurality of flow generators including a first type of flow generator and a second type of flow generator, wherein the humidifier is configured to electronically communicate with the plurality of flow generators through the communication connection;
wherein the first controller is configured to:
establish a communication with the first flow generator using the communication connection,
receive flow generator data from the first flow generator, and
change or prompt a change of an operating parameter or operating mode of the humidifier from a less preferable operating parameter or mode to a more preferable operating parameter or mode based at least in part on the flow generator data received by the first controller through the communication connection,
wherein the flow generator data corresponds to data stored in a memory of the flow generator.

2. The humidification system of claim 1 , wherein the humidifier comprises a user interface, the user interface configured to display the received flow generator data.

3. The humidification system of claim 2 , wherein the humidifier is configured to receive an indication of a desired operating parameter or a desired operating mode of the humidifier based on input provided through the user interface.

4. The humidification system of claim 3 , wherein the humidifier is configured to receive the indication of the desired operating parameter or operating mode of the humidifier based on input provided through the user interface of the first flow generator.

5. The humidification system of claim 4 , wherein the user interface of the first flow generator displays the prompt requesting input of the desired operating parameter or operating mode of the humidifier.

6. The humidification system of claim 5 , wherein the setting prompt requesting input of the desired operating parameter or operating mode comprises a request to confirm a default mode of the humidifier.

7. The humidification system of claim 1 , wherein the received flow generator data comprises at least one of a flow rate, a ventilation waveform, an error status, or a pressure.

8. The humidification system of claim 1 , further comprising a second communication connection configured to communicably couple the humidifier to a breathing circuit, wherein the humidifier is configured to electronically communicate with the breathing circuit through the second communication connection.

9. The humidification system of claim 8 , wherein the humidifier receives breathing circuit data from the breathing circuit through the second communication connection, wherein the humidifier transmits the breathing circuit data to the first flow generator through the communication connection, and wherein the first flow generator sets an operating parameter or operating mode based on the transmitted breathing circuit data.

10. The humidification system of claim 9 , wherein the humidifier is configured to automatically receive the breathing circuit data when the breathing circuit and the humidifier are coupled.

11. The humidification system of claim 1 , wherein the first flow generator is configured to communicate with a central monitoring system or electronic patient data recordation system, and wherein the first flow generator is configured to communicate the operating parameter or operating mode of the humidifier to the central monitoring system or electronic patient data recordation system.

12. The humidification system of claim 1 , wherein the first flow generator comprises a ventilator.

13. The humidification system of claim 8 , wherein the humidifier is configured to change the operating parameter or operating mode of the humidifier based at least in part on breathing circuit data received by the humidifier through the second communication connection.

14. The humidification system of claim 8 , wherein the humidifier receives breathing circuit data through the second communication connection, the breathing circuit data comprising at least one of a gases temperature or a flow rate.

15. The humidification system of claim 8 , wherein the humidifier receives breathing circuit data through the second communication connection, the breathing circuit data comprising an identification of the breathing circuit.

16. The humidification system of claim 8 , wherein the operating parameter or operating mode of the humidifier comprises at least one of a power level of a heater plate, a PID coefficient, a patient-end temperature set point, or a heater plate set point.

17. The humidification system of claim 9 , wherein the breathing circuit data comprises at least one of a compliance, a leak rate, or a dead space.

18. The humidification system of claim 1 , wherein the humidifier is configured to transmit humidifier data to a central monitoring system or electronic patient data recordation system.

19. The humidification system of claim 1 , wherein the communication connection comprises a wireless connection.

20. The humidification system of claim 8 , wherein the communication connection comprises a wireless connection and the second communication connection comprises a wireless connection.
