The severing of tracheal rings in tracheotomy is therefore most suitable for hurried operations in impending suffocation where the tube will probably be needed for a short time Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Williams, Walter Long, 1856-1945; Frost, James Nathan, joint author; Pfeiffer, Wilhelm, 1867-.
