Inspiratory airflow dyssynchrony. Sequence of airflow and airway pressure waveforms corresponding to a same patient in the same day ventilated in assist volume control mode. Set airflow is insufficient for the patient’s needs and originated different degrees of airflow dyssynchrony or starvation. a Mild airflow dyssynchrony. b, c The progression of airflow dyssynchrony through a more severe stage. d The appearance of double cycling secondary to a huge and large inspiratory effort
