          Continuous Flow Type Machine:  Delivery Of Inhalational Anesthetics

                                                                 Boyles Machine -1917

A Boyle’s machine is a continuous-flow anaesthetic machine designed to deliver a controlled mixture of gases (oxygen, nitrous oxide, air) and vapours (such as ether, later halothane, etc.) to patients during surgery.

Continuous Flow Anesthetic Machine 

1917 – First machine with nitrous oxide, oxygen, and ether vaporizer.

1920s–1930s – Modified versions with improved vaporizers and flowmeters.

Modern machines – Now include ventilators, scavenging systems, monitoring devices, and electronic controls, but still follow Boyle’s principles.
