AbstractThe inside and outside diameters of all endoscopes and tracheotomy tubes in the endoscopy suite were systematically measured. These measurements were correlated with the manufacturer's stated size and comparisons noted. A lack of uniformity was noted often among and between all product lines. In addition, endoscopes and tracheotomy tubes were not uniformly labeled with inside and outside diameters. As a result, the proper choice of a tracheotomy tube or endoscope for a patient's size and age may be confusing. A chart was developed and included in order to allow quick and accurate recognition of tracheotomy tube and endoscope sizes across product lines to aid in the proper selection of tracheotomy tubes and endoscopic equipment.
