Abstract

This disclosure describes systems and methods for monitoring and evaluating ventilatory parameters, analyzing those parameters and providing useful notifications and recommendations to clinicians. That is, modern ventilators monitor, evaluate, and graphically represent multiple ventilatory parameters. However, many clinicians may not easily recognize data patterns and correlations indicative of certain patient conditions, changes in patient condition, and/or effectiveness of ventilatory treatment. Further, clinicians may not readily determine appropriate ventilatory adjustments that may address certain patient conditions and/or the effectiveness of ventilatory treatment. Specifically, clinicians may not readily detect or recognize the presence of double triggering during ventilation. According to embodiments, a ventilator may be configured to monitor and evaluate diverse ventilatory parameters to detect double triggering and may issue notifications and recommendations suitable for a patient to the clinician when double triggering is implicated. The suitable notifications and recommendations may further be provided in a hierarchical format.

Claims

1. A ventilatory system with a smart prompt module for issuing a smart prompt when double triggering is implicated during a volume-control (VC) breath type of a patient, comprising:

at least one processor; and

at least one memory, communicatively coupled to the at least one processor and containing instructions executed by the at least one processor to;

detect that double triggering is implicated for a patient;

identify that the patient is being ventilated in a volume-control (VC) breath type, determine an appropriate notification, and determine an appropriate list of entries for mitigating the double triggering based at least in part on the volume-control (VC) breath type; and

display the appropriate notification message and the appropriate list of entries for mitigating the double triggering.

2. The ventilatory system of claim 1, wherein the smart prompt module further identifies processed ventilatory parameter data that implicated double triggering and determines the appropriate notification based at least in part on the processed ventilatory parameter data that implicated double triggering.

3. The ventilatory system of claim 2, wherein the appropriate notification comprises an alert that double triggering is implicated and information regarding the processed ventilatory parameter data that implicated double triggering.

4. The ventilatory system of claim 1, wherein the appropriate list of entries for mitigating the double triggering comprises a primary list of entries and a secondary list of entries.

5. The ventilatory system of claim 4, wherein the primary list of entries comprises one or more of:

increase inspiration time (T_I) by changing a flow pattern setting to decelerating ramp;

increase the inspiration time (T_I);

change the flow pattern to the decelerating ramp;

decrease a peak flow rate;

increase a set tidal volume (V_T);

change the flow pattern setting to square;

increase the peak flow rate; and

increase the peak flow rate to maintain the inspiration time (T_I).

6. The ventilatory system of claim 4, wherein the secondary list of entries comprises one or more of:

switch to spontaneous breath type ventilation;

switch to a volume-targeted-pressure-control (VC+) or a pressure-control (PC) breath type; and

switch to a proportional assist (PA), a pressure-support (PS), or a volume-support (VS) breath type.

7. The ventilatory system of claim 1, wherein the smart prompt module further identifies one or more ventilatory settings associated with a ventilatory treatment of the patient and determines the appropriate list of entries for mitigating the double triggering based at least in part on evaluating the one or more ventilatory settings.

8. The ventilatory system of claim 7, wherein the one or more ventilatory settings comprises:

set inspiration time (T_I);

ideal body weight (IBW)-predicted inspiration time; and

set flow pattern, and

wherein the smart prompt module determines the appropriate notification based at least in part on the one or more ventilatory settings for the patient by utilizing a notification module that at least one of;

determines set inspiration time (T_I),

determines ideal body weight (IBW)-predicted inspiration time,

determines the set flow pattern, wherein the flow pattern is selected from a group of modes of square and decelerating ramp,

determines if the set inspiration time (T_I) is ≧

the ideal body weight (IBW)-predicted inspiration time, and

determines if the set inspiration time (T_I) is <

the ideal body weight (IBW)-predicted inspiration time.

9. The ventilatory system of claim 8, wherein the one or more ventilatory settings further comprises tidal volume (VT), and wherein the smart prompt module determines the appropriate notification based at least in part on the one or more ventilatory settings for the patient by utilizing a recommendation module that at least one of:

determines the tidal volume (VT);

determines if the tidal volume (VT) is 8 ml/kg; and

determines if the tidal volume (VT) is >

8 ml/kg.

10. A graphical user interface for displaying one or more smart prompts corresponding to a detected condition, a ventilator configured with a computer having a user interface including the graphical user interface 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 smart prompt element for communicating information regarding a detected condition, wherein the detected condition is double triggering during a volume-control (VC) breath type of a patient, wherein the at least one smart prompt element further comprises at least one of a notification and one or more entries, wherein the notification comprises an alert associated with a detected implication of double triggering, and wherein the one or more entries comprise one or more suggestions for mitigating double triggering based at least in part on the volume-control (VC) breath type of the patient.

11. The graphical user interface of claim 10, wherein the one or more entries comprise one or more of an entry to:

increase inspiration time (TI) by changing a flow pattern setting to decelerating ramp;

increase the inspiration time (TI);

change the flow pattern setting to decelerating ramp;

decrease a peak flow rate;

increase a set tidal volume (VT);

change the flow pattern setting to square;

increase the peak flow rate to maintain the inspiration time (TI);

increase the peak flow rate;

switch to spontaneous breath type ventilation;

switch to a volume-targeted-pressure-control (VC+) or a pressure-control (PC) breath type; and

switch to a proportional assist (PA), pressure-support (PS), or a volume-support (VS) breath type.

12. A ventilatory system for issuing a smart prompt when double triggering is implicated during a volume-control (VC) breath type of a patient, comprising:
