  • SULFURHEXAFLUORIDE (SF6) VERSUS PERFLUOROPROPANE (C3F8) GAS

    Purpose: To compare outcomes of macular hole surgery using sulfurhexafluoride (SF6) versus perfluoropropane (C3F8) gas. Methods: This is a retrospective, interventional, comparative study. A total of 177 eyes of 166 patients operated over a 3-year period for idiopathic macular holes were included. Sixty-seven eyes had tamponade with SF6 gas (Group 1), whereas 111 eyes received C3F8 (Group 2) as the tamponading agent.

  • Gas tamponade recommended for retinal detachment involving

    Octafluoropropace (C3F8) and sulfur hexafluoride (SF6) are the typical gases utilized in vitrectomy surgery for tamponade. Visual recovery after retinal detachment surgery is limited by the length of time that gas remains in the eye. C3F8 has a longer half-life than SF6 gas.

  • SF6 gas as insulating and arc-quenching medium

    Sep 20, 2011 · Sulphur hexafluoride gas (SF6) is employed as insulation in all parts of the installation, and in the circuit-breaker also for arc-quenching. SF6 is an electronegative gas, its dielectric strength at atmospheric pressure is approximately three times that of air. It is incombustible, non-toxic, odourless, chemically inert with arc-quenching properties 3 to 4 times better than air at the same pressure.
