Abstract

This disclosure describes systems and methods for monitoring and evaluating ventilatory data to provide useful notifications and/or recommendations. Indeed, many clinicians may not easily identify or recognize data patterns and correlations indicative of certain patient conditions or the effectiveness of ventilatory treatment. Further, clinicians may not readily determine appropriate adjustments that may address certain patient conditions or the effectiveness of ventilatory treatment. Specifically, clinicians may not readily detect or recognize the occurrence of fluctuations in compliance during various types of ventilation. According to embodiments, a ventilator may be configured to monitor and evaluate diverse ventilatory parameters to detect an occurrence of and potential causes for fluctuations in compliance and may subsequently issue suitable notifications and/or recommendations. The suitable notifications and/or recommendations may further be provided in a hierarchical format such that the clinician may selectively access information regarding the fluctuation in compliance and/or potential causes for the fluctuation in compliance.

Claims

1. A ventilator-implemented method for detecting a fluctuation in compliance, the method comprising:

receiving one or more ventilatory settings, wherein the one or more ventilatory settings include a baseline compliance;

collecting ventilatory data;

processing the collected ventilatory data, wherein processing the collected ventilatory data includes trending compliance during ventilation of a patient;

analyzing the trended compliance comprising comparing the trended compliance to the baseline compliance;

detecting a decrease in compliance upon determining that the trended compliance is less than the baseline compliance; and

displaying a notification message when the decrease in compliance is detected.

2. The method of claim 1, further comprising:

retrieving patient data, wherein the patient data comprises at least one of;

a patient diagnosis, a patient predicted body weight (PBW), and a patent gender.

3. The method of claim 1, further comprising:

retrieving at least one secondary ventilatory parameter.

4. The method of claim 3, further comprising:

identifying one or more potential causes for the decrease in compliance based at least in part on the occurrence of both the decrease in compliance and the retrieved secondary ventilatory parameter.

5. The method of claim 4, wherein identifying the one or more potential causes for the decrease in compliance further comprises at least one of:

detecting low-delivered tidal volume (V_T) concurrently with the decrease in compliance;

detecting an increase in peak inspiratory pressure concurrently with the decrease in compliance; and

detecting an increase in mean airway pressure concurrently with the decrease in compliance.

6. The method of claim 4, wherein displaying the notification message includes displaying the one or more potential causes for the decrease in compliance.

7. The method of claim 6, further comprising:

determining one or more recommendations for addressing the decrease in compliance based on the determined one or more potential causes and at least some patient data; and

displaying the one or more recommendations.

8. The method of claim 7, wherein displaying the one or more recommendations further comprises:

displaying an icon for accessing the one or more recommendations, wherein upon activating the icon the one or more recommendations are displayed.

9. The method of claim 5, further comprising:

displaying an option to disable activation of the icon.

10. A ventilatory system for issuing a prompt when a decrease in compliance is detected, comprising:

at least one processor; and

at least one memory, communicatively coupled to the at least one processor and containing instructions that, when executed by the at least one processor, perform a method comprising;

detecting a decrease in compliance;

identifying one or more secondary ventilatory parameters occurring in conjunction with the decrease in compliance;

determining one or more recommendations for addressing the decrease in compliance, at least partially based on the identified secondary ventilatory parameter; and

displaying a prompt comprising one or more of;

an alert regarding the decrease in compliance;

a notification message displaying the one or more secondary ventilatory parameters occurring in conjunction with the decrease in compliance; and

a recommendation message displaying the one or more recommendations for addressing the decrease in compliance.

11. The ventilatory system of claim 10 wherein detecting the decrease in compliance further comprises:

retrieving compliance data;

trending the compliance data over a time period;

comparing the trended compliance data to a compliance threshold; and

determining that the compliance data breaches the compliance threshold.

12. The ventilatory system of claim 10, wherein the prompt comprises:

a primary prompt that includes the alert regarding the a decrease in compliance and the notification message displaying the one or more detected secondary ventilatory parameters; and

a secondary prompt that includes the recommendation message displaying the one or more recommendations for addressing the decrease in compliance.

13. The ventilatory system of claim 10, wherein the notification message displays at least one of:

a decrease in compliance detected concurrently with an increase in peak inspiratory pressure and a decrease in compliance detected concurrently with low-delivered tidal volume (V_T).

14. The ventilatory system of claim 10, wherein the recommendation message comprises one or more of:

consider checking patient for barotrauma; and

consider checking patient for fluid in lungs.

15. The ventilatory system of claim 10, wherein the recommendation message comprises one or more of:

consider checking for worsening pneumonia;

consider checking for endotracheal tube displacement; and

consider checking for pleural effusion.

16. A ventilator-implemented method for detecting a fluctuation in compliance, the method comprising:

receiving one or more ventilatory settings, wherein the one or more ventilatory settings include a baseline compliance;

collecting ventilatory data;

processing the collected ventilatory data, wherein processing the collected ventilatory data includes trending compliance during ventilation of a patient;

analyzing the trended compliance comprising comparing the trended compliance to the baseline compliance;

detecting an increase in compliance upon determining that the trended compliance is more than the baseline compliance; and

displaying a notification message when the increase in compliance is detected.

17. The method of claim 16, further comprising:

retrieving at least one secondary ventilatory parameter; and

identifying one or more potential causes for the increase in compliance based at least in part on the occurrence of both the increase in compliance and the retrieved secondary ventilatory parameter.

18. The method of claim 17, wherein identifying the one or more potential causes for the increase in compliance further comprises at least one of:

detecting high-delivered tidal volume (V_T) concurrently with the increase in compliance;

detecting a decrease in peak inspiratory pressure concurrently with the increase in compliance; and

detecting a decrease in mean airway pressure concurrently with the increase in compliance.

19. The method of claim 18, further comprising:

determining one or more recommendations for addressing the increase in compliance based on the determined one or more potential causes and at least some patient data; and

displaying the one or more recommendations, further including displaying an icon for accessing the one or more recommendations, wherein upon activating the icon the one or more recommendations are displayed.

20. The ventilatory system of claim 19, wherein the notification message displays:

an increase in patient inspiratory effort detected concurrently with the high-delivered V_T, and wherein the recommendation message comprises one or more of;

consider causes for the increase in patient inspiratory effort; and

consider increasing set V_T.
