Ventilator-initiated prompt regarding Auto-PEEP detection during volume ventilation of non-triggering patient
First Claim
1. A ventilator-implemented method for detecting Auto-PEEP during volume ventilation of a non-triggering patient, the method comprising:
- receiving one or more ventilatory settings associated with volume ventilation of the non-triggering patient;
collecting data associated with ventilatory parameters;
processing at least some of the collected ventilatory parameter data, wherein processing the collected ventilatory parameter data includes deriving ventilatory parameter data from at least some of the collected ventilatory parameter data;
analyzing the processed ventilatory parameter data, wherein analyzing the processed ventilatory parameter data comprises;
determining one or more predetermined thresholds for detecting Auto-PEEP based at least in part on the one or more ventilatory settings; and
monitoring whether the processed ventilatory parameter data breaches the one or more predetermined thresholds;
determining, by the ventilator, that Auto-PEEP is implicated for the non-triggering patient upon detecting that the processed ventilatory data breaches the one or more predetermined thresholds;
determining a list of entries for mitigating Auto-PEEP based at least in part on identifying the patient as non-triggering; and
issuing a smart prompt when Auto-PEEP is implicated, the smart prompt displaying;
a notification that Auto-PEEP is implicated; and
the list of entries for mitigating Auto-PEEP, comprising one or more of;
decrease respiratory rate;
increase flow;
adjust ventilatory settings until end-expiratory flow (EEF) approximates zero;
investigate reasons for increased resistance; and
investigate reasons for increased compliance.

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 a myriad of ventilatory parameters. However, many clinicians may not easily identify or 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 Auto-PEEP during volume ventilation of a non-triggering patient. According to embodiments, a ventilator may be configured to monitor and evaluate diverse ventilatory parameters to detect Auto-PEEP and may issue suitable notifications and recommendations to the clinician when Auto-PEEP is implicated. The suitable notifications and recommendations may further be provided in a hierarchical format.
