GE Healthcare celebrates 100 years of business. For a century the company has been at the forefront of anesthesia device innovation. Did you know that GE Healthcare holds more patents in anesthesia than any other company.

The business unit, originally formed as the Cleveland Dental Manufacturing Co. produced its first anesthesia delivery device in 1910, the Teter gas-oxygen apparatus, designed to deliver a safe mixture of nitrous oxide and oxygen to patients. The Teter device was developed by Charles K. Teter, a Cleveland, Ohio dentist who had an interest in producing a safe way to anesthetize patients as they could asphyxiate from pure nitrous oxide.

Today’s sophisticated anesthesia delivery systems couldn’t be more different from the Teter machine. GE Healthcare’s modern Carestations are the culmination of a century of innovation and deliver holistic care by harnessing critical intelligence and delivering patient data on demand – at the point of care. “We are proud of the contributions made by our predecessors to the advancement of medicine,” said Jeff Gal, General Manager of LSS, Perioperative. “We are adding to that legacy by developing innovative products that answer customer needs to improve patient outcomes and the patient experience.”
