2023-08-21

1. Hexafluoride ni uburozi?

Hexafluorideni physiologique inert kandi ifatwa nka gaze ya inert muri farumasi. Ariko iyo irimo umwanda nka SF4, ihinduka ibintu byuburozi. Iyo uhumeka cyane ya SF6, ibimenyetso bya asphyxia nka dyspnea, gutontoma, uruhu rwubururu hamwe na membrane, hamwe no guhungabana muri rusange.

2. Ese sulfure hexafluoride ituma ijwi ryawe riba hasi?

Guhindura amajwi yasulfur hexafluorideni ikinyuranyo cyijwi ryihinduka rya helium, kandi ijwi rirakomeye kandi rito. Iyo sulfur hexafluoride ihumeka, sulfur hexafluoride izuzuza imigozi yijwi. Iyo dukoze amajwi hamwe ninsinga zijwi zinyeganyega, igitera kunyeganyega ntabwo ari umwuka dusanzwe tuvuga ahubwo ni sulfur hexafluoride. Kuberako uburemere bwa molekuline ya sulfure hexafluoride nini kuruta uburemere busanzwe bwa molekile yumwuka, inshuro zinyeganyega ziri munsi yumuyaga, bityo hazaba ijwi ryimbitse kandi ryijimye kuruta uko byari bisanzwe.

3. Igihe kingana iki cya sulfur hexafluoride?

Ubuzima busanzwe bwa sulfur hexafluoride microbubbles munsi ya zeru ni umwaka 1.

4. Ese sulfure hexafluoride iruta dioxyde de carbone?

SF6sulfur hexafluorideni na gaze ya parike izwi cyane. Ugereranije na dioxyde de CO2 isanzwe imenyerewe, ubukana bwa SF6 sulfure hexafluoride bwikubye inshuro 23.500 za dioxyde de CO2. Byongeye kandi, SF6 sulfur hexafluoride ntishobora kubora bisanzwe. Ingaruka irashobora kumara imyaka irenga igihumbi; ibiranga kuba bihendutse kandi byoroshye gukoresha, bifatanije nibiranga ubushobozi bwo kubaho imyaka ibihumbi n'ibihumbi bitarangiritse, bituma iyi gaze yanduzwa cyane kandi ihumanya cyane muri "kubyara amashanyarazi".

5. Hejuru ya sulfure hexafluoride irenze umwuka duhumeka?

Gazi ya SF6 ntabwo ifite ibara, ubujiji, ntabwo ari uburozi, ntabwo yaka, na gaze ihamye. SF6 ni gaze iremereye cyane, iremereye inshuro 5 kurenza ikirere mubihe bisanzwe.

6. Ese sulfure hexafluoride ni ibiyobyabwenge?

Ingaruka mbi za sulfur hexafluoride ku mubiri wumuntu mubisanzwe zoroheje kandi zigihe gito, kandi zirashobora gukira mu buryo bwikora nta rukurikirane. Sulfure hexafluoride ni umuti wo gusuzuma ukoreshwa mu bizamini bya ultrasound, ibizamini bya echocardiografiya, hamwe na Doppler yo mu maraso kugira ngo hamenyekane indwara. Sulfure hexafluoride ikoreshwa mugupima ultrasonic kandi igomba gukoreshwa mubigo byubuvuzi bifite ibihe byihutirwa kandi bifite ibikoresho byubutabazi, kandi bigomba guterwa na muganga. Niba allergic reaction ibaye mugihe cyangwa nyuma yo gukoresha sulfur hexafluoride, bizagaragara nka erythma y'uruhu, bradycardia, hypotension ndetse na anafilactique. Niba ufite ibimenyetso simusiga kandi byaho, ugomba kubimenyesha muganga cyangwa ukajya mubitaro kwisuzumisha. Nyuma yo gufata imiti, ni ngombwa kwitegereza mu kigo cy’ubuvuzi bireba igice cyisaha kugirango wirinde allergie. Gukoresha sulfur hexafluoride ku barwayi bafite indwara z'umutima n'imitsi bishobora kongera indwara z'umutima.
