Simulated screenshot of flow starvation in volume control continuous mandatory ventilation. Simulated screenshot of flow starvation in volume control continuous mandatory ventilation. Shown is a graphical representation of a volume-controlled breath in the presence of a simulated patient respiratory effort. The green line represents airway pressure at the mouth opening. When the airway pressure drops below baseline (PEEP) a mismatch between patient's flow needs and the ventilator flow delivery is present. The drop in pressure below baseline is interpreted as no work of breathing support by the ventilator. John D Davies et al. Respir Care 2016;61:774-790 (c) 2012 by Daedalus Enterprises, Inc.
