Siv
Retinal vitreous phais
Perfluorodecalin feem ntau yog siv nyob rau hauv retinal vitreous phais hauv kev kho mob, tshwj xeeb tshaj yog nyob rau hauv kev sim luav, qhov twg nws yuav siv tau raws li ib tug tamponade. Perfluorodecalin tamponades kav ntev tshaj li ob hnub yog teeb meem rau retina, tab sis nws tuaj yeem siv los kawm cov kua muag loj heev.
Cov ntshav hloov
Perfluorodecalin tuaj yeem siv los hloov ntshav vim nws cov pa oxygen zoo - nqa lub peev xwm. Hauv qee qhov kev xav tau thiab cov pa oxygen ib feem ntawm lub siab, nws cov pa solubility yog 20 npaug ntawm cov dej thiab 2 zaug siab dua li cov ntshav. Qhov no ua rau nws ua tau zoo nyob rau hauv ib puag ncig uas xav tau ntau cov pa oxygen, xws li dhia dej lossis siab - qhov chaw siab.
Tshuaj pleev ib ce thiab cov khoom siv tu tus kheej
Vim nws muaj peev xwm yaj thiab hloov cov pa oxygen rau ntawm daim tawv nqaij, Perfluorodecalin kuj tseem siv tau los ua cov tawv nqaij txias hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej los pab txhim kho cov pa oxygen thiab kev noj qab haus huv ntawm daim tawv nqaij.
