Experimental set-up of the electromechanical pressure–volume ventilation apparatus (right) interfaced with the digital image correlation system (left). The Trilion ARAMIS Adjustable 12M two-camera system is positioned above a transparent, air-tight tank containing the lung specimen which is controlled by the dual-piston apparatus to apply inflation volumes and measure resulting lung volumes and pressures. The combination of these two systems enables the simultaneous collection of global pressures and volumes and local lung topological strain measurements
