Kev siv
Retinal vitreous phais
Perfluorodecalin feem ntau yog siv hauv kev phais mob vityinal hauv cov kev sim khomob, tshwj xeeb hauv cov luav, qhov uas nws tuaj yeem siv ua tamponade. PerfLuorodecalin tamponades kav ntev tshaj li ob hnub yog kev tsim txom rau lub retina, tab sis nws tuaj yeem siv los kawm txog kev ua kua muag.
Ntshav hloov
Perfluorodredecalin tuaj yeem siv raws li cov ntshav hloov vim tias nws cov pa zoo - nqa peev xwm. Nyob rau qee yam kev nplua thiab oxygen ib nrab siab mob, nws cov oxygen solubility yog 20 zaug dej thiab 2 npaug siab tshaj li cov ntshav. Qhov no ua rau nws ua tau zoo nyob rau hauv ib puag ncig uas yuav tsum muaj ntau ntawm cov pa oxygen, xws li dhia dej lossis siab - Altitude ib puag ncig.
Tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej
Vim nws muaj peev xwm yaj thiab hloov oxygen rau ntawm daim tawv nqaij, PerfleLuorodecalin kuj tseem siv tau cov tawv nqaij thiab cov khoom tu tus kheej los pab kho cov pa oxygen thiab kev noj qab haus huv ntawm daim tawv nqaij.
