Two sided chestpiece with tunable diaphragms on both the adult and pediatric sides. Single piece tunable diaphragm is easy to attach and easier to clean because its surface is smooth without crevices. Pediatric side converts to a traditional open bell by replacing the single piece diaphragm with a nonchill rim. Tubing provides longer life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains.
