Silicone and Rubber Masks
Silicone and rubber oxygen masks are heavier than plastic masks. They are designed to provide a good seal for long-duration use by aviators, medical research subjects, and hyperbaric chamber and other patients that require administration of pure oxygen, such as carbon monoxide poisoning and decompression sickness victims. Dr. Arthur Bulbulian pioneered the first modern viable oxygen mask, worn by World War II pilots and used by hospitals. Valves inside these tight-fitting masks control the flow of gases into and out of the masks, so that rebreathing of exhaled gas is minimised.

Famous quotes containing the words rubber and/or masks:
“Time for the flat-headed man. I recognize that listener,
Him with the platitudes and rubber doughnuts,
Melting at the knees, a varicose horror.
Hello, hello. My nerves knew you, dear boy.
Have you come to unhinge my shadow?”
—Theodore Roethke (1908–1963)
“Life will show you masks that are worth all of your carnivals.”
—Ralph Waldo Emerson (1803–1882)
