The Cardiology IV stethoscope’s advanced features help you achieve more.
-
Better audibility of high-frequency sounds¹ helps you learn more about your patient’s condition.
-
Single-piece tunable diaphragms let you hear high and low frequency sounds on both the adult and pediatric sides of the chestpiece.
-
Pediatric side converts to an open bell. Just remove the single-piece diaphragm and replace it with a non-chill rim.
-
Open bell stays clear of dirt and debris by covering it with the small diaphragm.
-
Dual-lumen tubing combines two sound paths in one tube, eliminating the rubbing noise of traditional double tubes.
-
Not made with natural rubber latex or phthalate plasticizers, next-generation
tubing has improved resistance to skin oils and alcohol and is less likely to pick up stains. -
