US 9,038,633 B2 · Ventilator-initiated prompt regarding high delivered tidal volume

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 VT, 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 VT, 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 VT, and/or potential causes for the high-delivered VT.

Dependent claims

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

receiving one or more ventilatory settings, wherein the one or more ventilatory settings include a threshold VT;
collecting ventilatory data;
processing the collected ventilatory data, wherein processing the collected ventilatory data includes determining a delivered VT;
analyzing the delivered VT, comprising comparing the delivered VT, to the threshold VT;
detecting high-delivered VT, upon determining that the delivered VT, is greater than the threshold VT;
identifying one or more potential causes for the high-delivered VT, comprising one or more of:
detecting an increase in compliance concurrently with the high-delivered VT;
detecting a decrease in resistance concurrently with the high-delivered VT;
and
detecting an increase in patient inspiratory effort concurrently with the high-delivered VT;
and
displaying a smart prompt when high-delivered VT is detected.

9 more elements

A ventilatory system for issuing a smart prompt when high-delivered tidal volume (VT) 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, cause the ventilatory system to:
detect high-delivered VT ;
identify one or more potential causes for the high-delivered VT, comprising one or more of:
detect an increase in compliance concurrently with the high-delivered VT;
detect a decrease in resistance concurrently with the high-delivered VT;
and
detect an increase in patient inspiratory effort concurrently with the high-delivered VT;
determine one or more recommendations for addressing the high-delivered VT;
and
display a smart prompt, the smart prompt comprising one or more of:
an alert regarding the high-delivered VT;
a notification message displaying the one or more potential causes for the high-delivered VT;
and
a recommendation message displaying the one or more recommendations for addressing the high-delivered VT.
