Fig. 1. “Choose-the-hole” model designed by Dr. Arthur Frederick David Cole (Assistant Professor, University of Toronto, Toronto, Ontario, Canada). 8The model consists of three wooden panels with holes mounted on a wooden base. Syringe barrels are inserted into the holes in various combinations. Subjects refine their manipulation skills by passing the fiberoptic bronchoscope under fiberoptic vision through a given syringe barrel combination with the model covered.
