WebOct 18, 2024 · We add helium to the diver’s breathing gas for a few reasons depending on the planned dive. For depths from 197 to 213 feet (60 to 65 m), we consider trimix diving appropriate to reduce nitrogen … Helium diluted breathing gases are used to eliminate or reduce the effects of inert gas narcosis, and to reduce work of breathing due to increased gas density at depth. From the 1960s saturation diving physiology studies were conducted with helium from 45 to 610 m (148 to 2,001 ft) over several decades by a Hyperbaric Experimental Centre operated by a French company specializing i…
WebPublished estimates report anywhere from 0.5 million to 4 million people in the United States participate in recreational diving; many travel to tropical areas of the world to dive. Divers face a variety of medical challenges, but because dive injuries are generally rare, few clinicians are trained in their prevention, diagnosis, and treatment.

Trimix is a breathing gas consisting of oxygen, helium and nitrogen and is used in deep commercial diving, during the deep phase of dives carried out using technical diving techniques, and in advanced recreational diving. The helium is included as a substitute for some of the nitrogen, to reduce the narcotic effect … See more The main reason for adding helium to the breathing mix is to reduce the proportions of nitrogen and oxygen below those of air, to allow the gas mix to be breathed safely on deep dives. A lower proportion of nitrogen is required … See more Lowering the oxygen content of a breathing gas mixture increases the maximum operating depth and duration of the dive before which oxygen toxicity becomes a limiting factor. Most trimix divers limit their working oxygen partial pressure [PO2] to … See more The term trimix implies that the gas has three functional components, which are helium, nitrogen and oxygen. Since the nitrogen and all or part of the oxygen is usually provided … See more Gas blending of trimix generally involves mixing helium and oxygen with air to the desired proportions and pressure. Two methods are in common use: Partial pressure blending is done by decanting oxygen and helium into the diving cylinder and … See more Helium conducts heat six times faster than air, so helium-breathing divers often carry a separate supply of a different gas to inflate drysuits.
