Fig. 5From: Flow-controlled ventilation (FCV) improves regional ventilation in obese patients – a randomized controlled crossover trialExemplary global thoracic electrical impedance (EITh) during two tidal breathes of flow-controlled ventilation (FCV) and volume-controlled ventilation (VCV) in one obese patient. For further comparison, decrease in impedance during expiration was separated into four equal sections (ΔEI25, ΔEI50, ΔEI75 and ΔEI100) and matched with simultaneous tidal changes (comp.
