  • INTRAVITREAL SULFUR HEXAFLUORIDE INJECTION FOR THE TREATMENT

    Purpose: Vitreomacular traction (VMT) syndrome can cause symptomatic metamorphopsia and decreased visual acuity. Although it is typically treated with vitrectomy or intravitreal ocriplasmin injection, these procedures can be invasive and costly. The purpose of this retrospective, consecutive case series was to evaluate the efficacy of intravitreal expansile sulfur hexafluoride gas injection for the treatment of symptomatic VMT syndrome.

    The gas is usually injected at 100% concentration and will expand a bit over the first day or so. This allows us to inject a small amount of gas that will enlarge and cover more retinal surface area. Gases used are usually SF6 (sulfur hexafluoride), C2F6 (hexafluoroethane) and C3F8 (octafluoropropane).

  • Ultra-Trace Analysis Technique for SF6 Using Gas

    Abstract. Sulfur hexafluoride (SF 6) is widely used as a tracer gas because of its detectability at low concentrations. This attribute of SF 6 allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. SF 6 high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments by reducing quantity requirements.

    Full Text. Abstract. • In this pilot study, sulfur hexafluoride (SF 6 ), a nontoxic inert gas infused into the ear during myringotomy and acting as a gas cushion behind an intact eardrum, was tested on five children with bilateral serous otitis media. The contralateral ear was treated with air as a control. A significant difference in air-bone gaps (frequencies, 0.5, 1.0, and 2.0 kHz) lasting at least eight weeks was found between the ears treated with SF 6 and the air-treated ears.

  • Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for SF6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used SF6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect SF6 emissions from electric power systems, such as the type and age of the SF6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of SF6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of SF6can impact the climate. The electric power industry uses roughly 80 percent of all SF6 produced worldwide. Ideally, none of this gas would b...
