From: The effect of unilateral chest drainage for transpulmonary pressure during mechanical ventilation
A lung-thorax cavity model, to which respirometers and a chest tube were connected, is shown. Two plastic containers each contain a 1-L test lung, which can be ventilated via the standard elbow connector. The tidal volume of each test lung was measured by a flow sensor connected to the ventilator side of the standard elbow connector, and the total tidal volume of both was measured by the flow sensor built into the ventilator. The plastic container has a 1.5-m tube connected to the thorax model (arrow), which is connected to the chest tube drainage system
