WebDec 3, 2024 · There are three main forms of interaction between the patient and ventilator, each of may be problematic and managed differently. Trigger Asynchrony – related to breath initiation. Phase Asynchrony – related to breath duration. Flow and Volume Mismatching – related to ventilator settings of inspiratory flow and/or tidal volume. WebVentilator waveforms are helpful to identify dyssynchrony, which can be divided into trigger, flow, cycle, and expiratory dyssynchrony. Ventilator waveforms allow the clinician to assess changes in respiratory mechanics, and can be useful in monitoring the progression of disease pathology and response to therapy. church\u0027s hermes slippers
