Abstract

A breathing support system is provided. The system may include a breathing support device configured to deliver gas to a patient and a display device associated with the breathing support device. The display device may be configured to display a graphic indicating one or more measures regarding the patient'"'"'s work of breathing.

Claims

1. A breathing support system, comprising:

a breathing support device configured to deliver gas to a patient;

a software-generated graphic indicating one or more measures regarding the patient'"'"'s work of breathing;

a display device associated with the breathing support device, the display device configured to display the software-generated graphic,

wherein the software-generated graphic includes;

a scale; and

one or more work of breathing indicators that move relative to the scale.

2. A system according to claim 1, further comprising a work of breathing calculation module configured to receive data from one or more sensors and calculate the one or more measures using one or more work of breathing algorithms.

3. A system according to claim 2, wherein the data received by the work of breathing calculation module comprises data regarding delivery of gas to the patient, including at least one of pressure and flow of gas delivered to the patient.

4. A system according to claim 2, wherein the work of breathing calculation module is configured to receive data from one or more sensors associated with an artificial airway inserted in the patient.

5. A system according to claim 1, further comprising:

one or more sensors configured to obtain data regarding the patient'"'"'s breathing;

a memory device storing one or more work of breathing algorithms; and

a processor communicatively coupled to the one or more sensors and the memory device and configured to determine the one or more measures regarding the patient'"'"'s work of breathing based at least on data obtained by the one or more sensors and the one or more work of breathing algorithms.

6. A system according to claim 5, wherein the one or more sensors are associated with an artificial airway inserted in the patient.

7. A system according to claim 5, wherein the one or more sensors are not associated with an artificial airway inserted in the patient.

8. A system according to claim 1, wherein the display device is at least partially integrated with the breathing support device.

9. A system according to claim 1, wherein the display device is physically separate from the breathing support device.

10. A system according to claim 1, wherein the software-generated graphic includes:

a total work of breathing indicator indicating a measure of the patient'"'"'s total work of breathing, the total work of breathing comprising a patient work of breathing component and a device work of breathing component, the patient work of breathing component comprising the portion of the total work of breathing provided by the patient and the device work of breathing component comprising the portion of the total work of breathing provided by the breathing support device.

11. A system according to claim 1, wherein the software-generated graphic further includes an indication of an elastic work of breathing component relative to a resistive work of breathing component.

12. A display according to claim 1, wherein the one or more measures comprise one or more estimated measures regarding the patient'"'"'s work of breathing.

13. A system according to claim 1, wherein the software-generated graphic includes:

an elastic-resistive indicator indicating a measure of the elastic work of breathing component relative to a measure of the resistive work of breathing component.

14. A system according to claim 1, wherein the software-generated graphic includes:

an elastic-resistive graphic including a first portion and a second portion, the first portion indicating a measure of an elastic work of breathing component and the second portion indicating a measure of a resistive work of breathing component; and

wherein relative sizes of the first and second portions of the elastic-resistive graphic dynamically adjust to indicate the measure of the elastic work of breathing component relative to the measure of the resistive work of breathing component.

15. A system according to claim 14, wherein the size of the elastic-resistive graphic remains constant as the relative sizes of the first and second portions dynamically adjust.

16. A breathing support system, comprising:

a breathing support device configured to deliver gas to a patient;

a software-generated graphic indicating one or more measures regarding the patient'"'"'s work of breathing;

a display device associated with the breathing support device, the display device configured to display the software-generated graphic, and

wherein the software-generated graphic includes;

an elastic-resistive graphic including a first portion and a second portion, the first portion indicating a measure of an elastic work of breathing component and the second portion indicating a measure of a resistive work of breathing component; and

wherein relative sizes of the first and second portions of the elastic-resistive graphic dynamically adjust on a bar to indicate the measure of the elastic work of breathing component relative to the measure of the resistive work of breathing component.

17. A system according to claim 16, wherein the size of the elastic-resistive graphic remains constant as the relative sizes of the first and second portions dynamically adjust.

18. A system according to claim 16, further comprising a work of breathing calculation module configured to receive data from one or more sensors and calculate the one or more measures regarding the patient'"'"'s work of breathing using one or more work of breathing algorithms.

19. A system according to claim 18, wherein the data received by the work of breathing calculation module comprises data regarding delivery of gas to the patient, including at least one of pressure and flow of gas delivered to the patient.

20. A system according to claim 16, further comprising:

one or more sensors configured to obtain data regarding the patient'"'"'s breathing;

a memory device storing one or more work of breathing algorithms; and

a processor communicatively coupled to the one or more sensors and the memory device and configured to determine the one or more measures based at least on data obtained by the one or more sensors and the one or more work of breathing algorithms.
