Fig. 4From: Dorsal recruitment with flow-controlled expiration (FLEX): an experimental study in mechanically ventilated lung-healthy and lung-injured pigsRegional ventilation delay for the healthy lung under volume-controlled ventilation (VCV) (a), flow-controlled expiration (FLEX) ventilation (b) and second VCV period (c). Colder (darker blue) colors represent lung areas that participate early in the ventilation, warmer (lighter blue) colors are areas with a delay in inspiration starting time. A larger fraction of lung area participates earlier in ventilation when using FLEX ventilation. This effect is nearly mitigated after switching off FLEX ventilationBack to article page
