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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The method of claim 1, wherein the delivered VT is determined by integrating inspiratory flow over inspiratory time (TI). ### Claim 3 (depends on 1) The method of claim 1, wherein the delivered VT is determined by integrating expiratory flow over expiratory time (TE). ### Claim 4 (depends on 1) The method of claim 1, wherein displaying the smart prompt includes displaying the one or more potential causes for the high-delivered VT. ### Claim 5 (depends on 1) The method of claim 1, wherein detecting an increase in compliance comprises: retrieving compliance data; comparing the compliance data to a compliance threshold; and determining that the compliance data breaches the compliance threshold. ### Claim 6 (depends on 1) The method of claim 1, wherein detecting a decrease in resistance comprises: retrieving resistance data; comparing the resistance data to a resistance threshold; and determining that the resistance data breaches the resistance threshold. ### Claim 7 (depends on 1) The method of claim 1, wherein detecting an increase in patient inspiratory effort comprises: retrieving patient effort data; comparing the patient effort data to an effort threshold; and determining that the patient effort data breaches the effort threshold. ### Claim 8 (depends on 1) The method of claim 1, wherein the smart prompt comprises: a primary prompt that includes an alert regarding the high-delivered VT, and the one or more potential causes for the high-delivered VT; and a secondary prompt that includes one or more recommendations for addressing the high-delivered VT. ### Claim 9 (depends on 4) The method of claim 4, wherein displaying the smart prompt includes displaying one or more recommendations for addressing the high-delivered VT. ### Claim 10 A ventilatory system for issuing a smart prompt when high-delivered tidal volume (VT) is detected, comprising: at least one processor;
