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 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 .
