Methods and systems for automated detection of water accumulation on ventilator airway circuits from airway pressure and flow

A system for automated detection of water accumulation, comprising:

• a ventilator device utilized to ventilate a patient, the ventilator device configured to provide an airway pressure waveform and a flow waveform for a single breath of the patient;
• a trained asynchrony detection algorithm;
• a processor configured to:
• (i) perform multiple iterations of:
• calculating, using the received airway pressure waveform, an airway pressure water accumulation index;
• calculating, using the received flow waveform, a flow water accumulation index;
• labeling, using at least the calculated airway pressure water accumulation index and the calculated flow water accumulation index as input features to the trained asynchrony detection algorithm, the single breath of the patient as synchronous or asynchronous, wherein an asynchronous breath is further labeled as auto-triggered, double-triggered, or ineffectively triggered;
• and ranking, by the trained asynchrony detection algorithm, all of the input features based on an importance of each respective input feature to the determination of the single breath of the patient as synchronous or asynchronous by the trained asynchrony detection algorithm, comprising at least a determination of a most important input feature;
• and (ii) for the plurality of iterations:
• determine, by the trained asynchrony detection algorithm:
• (1) a most frequent breath labeling for the plurality of iterations, wherein the most frequent breath labeling is one of synchronous, auto-triggered, double-triggered, or ineffectively triggered, and (2) a most frequent most important input feature for the plurality of iterations;
• and (3) a most frequent most important input feature for each of the synchronous, auto-triggered, double-triggered, and ineffectively triggered breath labels;
• and determine, by the trained asynchrony detection algorithm using the most frequent breath labeling for the plurality of iterations, the most frequent most important input feature for the plurality of iterations, and the most frequent most important input feature for each of the synchronous, auto-triggered, double-triggered, and ineffectively triggered breath labels, one or more of:
• (1) water accumulation in the ventilator device and an action to remove the water accumulation from the ventilator device;
• and (2) asynchrony in the ventilator device due to a cause other than water accumulation, and an action to correct the asynchrony;
• and
• a user interface configured to provide the determined action to remove the water accumulation from the ventilator device or the determined action to correct the asynchrony.
