The respiratory model. Experimental system used in the study. The airway model (Fig. 1) was connected to the lung model. The physiological dead space was adjusted to 3 mL/kg. The respiratory patterns of the lung model could be changed, and the model had pressure sensors to measure the internal pressure. Sampling tubes were connected to the capnogram at each site mentioned
