Disposable airways provide superior performance. Unobstructed passage -unique perforated midway openings assure ventilating channel and permit access of a suction catheter even if airway shifts or is partially occluded. Strength -reinforced bite block prevents collapse of airway. Flexibility -smooth non-brittle finish permits easy insertion without danger of breaking when distorted. Less trauma -greater accessibility of suction catheter permits removal of secretions at a faster rate.
