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 high-delivered V_T 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 high-delivered V_T 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 high-delivered V_T and/or potential causes for the high-delivered V_T.

Claims

1-20. -20. (canceled)

21. A ventilator-implemented method for detecting high-delivered tidal volume (V_T), the method comprising:

receiving a setting for a threshold V_T;

determining a tidal volume delivered to a patient (delivered V_T);

detecting high-delivered V_T upon determining that the delivered V_T is greater than the threshold V_T;

identifying one or more potential causes for the high-delivered V_T comprising one or more of;

detecting an increase in compliance concurrently with the high-delivered V_T;

detecting a decrease in resistance concurrently with the high-delivered V_T; and

detecting an increase in patient inspiratory effort concurrently with the high-delivered V_T; and

displaying a prompt when high-delivered V_T is detected.

22. The method of claim 21, wherein the delivered V_T is determined by integrating inspiratory flow over inspiratory time (T_I).

23. The method of claim 21, wherein the delivered V_T is determined by integrating expiratory flow over expiratory time (T_E).

24. The method of claim 21, wherein displaying the prompt includes displaying the one or more potential causes for the high-delivered V_T.

25. The method of claim 21, wherein displaying the prompt includes displaying one or more recommendations for addressing the high-delivered V_T.

26. The method of claim 21, wherein the prompt comprises:

a primary prompt that includes an alert regarding the high-delivered V_T and the one or more potential causes for the high-delivered V_T; and

a secondary prompt that includes one or more recommendations for addressing the high-delivered V_T.

27. A ventilatory system for detecting high-delivered tidal volume (V_T), the ventilator system 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, cause the ventilatory system to:

detect high-delivered V_T;

identify one or more potential causes for the high-delivered V_T comprising one or more of;

detect an increase in compliance concurrently with the high-delivered V_T;

detect a decrease in resistance concurrently with the high-delivered V_T; and

detect an increase in patient inspiratory effort concurrently with the high-delivered V_T; and

display a prompt regarding the high-delivered V_T.

28. The ventilator system of claim 27, wherein the prompt comprises one or more of:

a notification message displaying the one or more potential causes for the high-delivered V_T; and

a recommendation message displaying one or more recommendations for addressing the high-delivered V_T.

29. The ventilatory system of claim 27, wherein the prompt comprises:

a primary prompt that displays the one or more potential causes for the high-delivered V_T; and

a secondary prompt that displays one or more recommendations for addressing the high-delivered V_T.

30. The ventilator system of claim 29, wherein the secondary prompt is displayed upon receiving a selection.

31. The ventilatory system of claim 28, wherein the notification message displays at least one of:

an increase in compliance detected concurrently with the high-delivered V_T; and

a decrease in resistance detected concurrently with the high-delivered V_T.

32. The ventilatory system of claim 31, wherein the recommendation message displays:

consider decreasing inspiratory pressure (P₁).

33. The ventilatory system of claim 28, wherein the notification message displays at least one of:

an increase in compliance detected concurrently with the high-delivered V_T; and

a decrease in resistance detected concurrently with the high-delivered V_T.

34. The ventilatory system of claim 33, wherein the recommendation message displays:

consider decreasing pressure support (P_SUPP).

35. The ventilatory system of claim 28, wherein the notification message displays:

an increase in patient inspiratory effort detected concurrently with the high-delivered V_T.

36. The ventilatory system of claim 35, wherein the recommendation message displays one or more of:

consider causes for the increase in patient inspiratory effort;

consider decreasing inspiratory pressure (P_I);

consider increasing set V_T; and

consider decreasing pressure support (P_SUPP).

37. A ventilator processing interface for displaying a prompt in response to detecting high-delivered tidal volume (V_T), comprising:

means for detecting the high-delivered V_T;

means for identifying one or more potential causes for the high-delivered V_T, comprising one or more of;

means for detecting an increase in compliance concurrently with the high-delivered V_T;

means for detecting a decrease in resistance concurrently with the high-delivered V_T; and

means for detecting an increase in patient inspiratory effort concurrently with the high-delivered V_T; and

means for displaying the prompt including the one or more potential causes for the high-delivered V_T.

38. The ventilator processing interface of claim 37, further comprising:

means for determining one or more recommendations for addressing the high-delivered V_T, wherein the displaying prompt further includes the one or more recommendations for addressing the high-delivered V_T.

39. A graphical user interface of a ventilator for displaying one or more prompts, the graphical user interface communicatively coupled to the ventilator for accepting commands and for displaying information, the graphical user interface comprising:

at least one window; and

one or more elements within the at least one window comprising at least one prompt element for communicating information upon detecting high-delivered tidal volume (V_T), wherein the information comprises one or more potential causes for the detected high-delivered V_T that include one or more of;

an increase in compliance, a decrease in resistance, and an increase in patient inspiratory effort.

40. The graphical user interface of claim 39, wherein the at least one prompt element further comprises at least one of a notification message and a recommendation message, wherein the notification message comprises an alert associated with the detected high-delivered V_T, and wherein the recommendation message comprises one or more recommendations for addressing the detected high-delivered V_T.
