What does this small bump at the beginning of expiration represent?

 

Answer: Premature cycling. The patient is still making an inspiratory effort when the ventilator cycles to expiration. The image below shows esophageal pressure, as well as pressure and flow, with the blue, vertical line indicating the end of the patient’s inspiratory effort. You should try to prolong insufflation by lowering the percentage of expiratory trigger sensitivity (ETS).
