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 work of breathing graphic indicating one or more work of breathing measures regarding the patient's breathing.

Claims (43)

1. A breathing support system, comprising:

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

a software-generated image representing a work of breathing graphic indicating one or more work of breathing measures regarding the patient's breathing, wherein the one or more work of breathing measures include an elastic work of breathing component and a resistive work of breathing component;

a software-generated image representing an elastic work of breathing indicator indicating a measure of the elastic work of breathing component;

a software-generated image representing a resistive work of breathing indicator indicating a measure of the resistive work of breathing component; and

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

wherein the software-generated image representing the work of breathing graphic includes:

a software-generated image representing a scale; and

one or more software-generated images representing work of breathing indicators that move relative to the software-generated image representing the scale to indicate the one or more work of breathing measures.

2. The 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 work of breathing measures using one or more work of breathing algorithms.

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

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

5. The 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 work of breathing measures based at least on the data obtained by the one or more sensors and the one or more work of breathing algorithms.

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

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

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

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

10. The system according to claim 1 , wherein the software-generated image representing the work of breathing graphic includes:

a software-generated image representing a total work of breathing indicator indicating a measure of a total work of breathing for the patient's 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 a patient and the device work of breathing component comprising a portion of the total work of breathing provided by the breathing support device.

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

12. The display according to claim 1 , wherein the one or more work of breathing measures comprise one or more estimated measures.

13. The system according to claim 1 , wherein the software-generated image representing the work of breathing graphic includes:

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

14. The system according to claim 1 , wherein the work of breathing graphic includes:

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

wherein relative sizes of the first and second portions of the elastic-resistive work of breathing 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. The system according to claim 14 , wherein a size of the elastic resistive work of breathing 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 image representing a work of breathing graphic indicating one or more work of breathing measures regarding the patient's breathing, wherein the one or more work of breathing measures include an elastic work of breathing component and a resistive work of breathing component;

a software-generated image representing an elastic work of breathing indicator indicating a measure of the elastic work of breathing component;

a software-generated image representing a resistive work of breathing indicator indicating a measure of the resistive work of breathing component; and

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

wherein the software-generated image representing the work of breathing graphic includes:

a software-generated image representing a patient's work of breathing indicator indicating a measure of the patient's work of breathing, the patient's work of breathing comprising a work of breathing provided by the patient, patient's work of breathing comprising a patient elastic work of breathing component and a patient resistive work of breathing component;

the software-generated image representing the elastic work of breathing indicator indicating the measure of the patient elastic work of breathing component;

the software-generated image representing the resistive work of breathing indicator indicating the measure of the patient resistive work of breathing component; and

a software-generated image representing a scale,

wherein the software-generated image representing the patient's work of breathing indicator dynamically moves relative to the software-generated image representing the scale to indicate the measure of the patient's work of breathing, and

wherein the software-generated image representing the elastic work of breathing indicator and the software-generated image representing the resistive work of breathing indicator move along with the software-generated image representing the patient's work of breathing indicator relative to the scale.
