A imaski engeyiyo yokuphefumlasisixhobo sonyango esikhethekileyo esikunceda ekuboneleleni ngeoksijini kwiimeko zikaxakeka.Ezi maski zinceda abantu abasakwazi ukuziphefumlela kodwa bafuna ioksijini eninzi eyongezelelweyo.
Imaski engaphefumliyo ibandakanya iindawo ezine ezibalulekileyo:
• Imaski
• Ingxowa yokugcina amanzi
• Iivalvu ezi-2 ukuya kwezi-3 zendlela enye
• Imibhobho yokudibanisa ingxowa yokugcina amanzi kwitanki yeoksijini
Ioksijini iphuma etankini iye kwingxowa yokugcina amanzi.Ivalve yendlela enye idibanisa ingxowa yokugcina amanzi kwimaski.Xa umntu ephefumla ngaphakathi, ioksijini isuka engxoweni iye kwisigqubuthelo sobuso.
Iivalve zendlela enye.Xa umntu ephefumla, ivalve yendlela enye ithintela umoya wakhe ukuba ungabuyeli kwisingxobo sokugcina amanzi.Endaweni yoko, i-exhale ityhala umoya ngevalvu enye okanye ezimbini ezongezelelweyo zendlela enye ngaphandle kwemaski.Ezi zivalo zikwathintela umntu ukuba angaphefumli umoya kwigumbi lonke.
Iimaski ezingaphefumliyoziyilelwe ukuhambisa ioksijini eninzi eyongezelelweyo kwindlela yakho yomoya.Iqhekeza eliqhelekileyo le-oksijini ephefumlelweyo (FIO2), okanye ukuxinwa kwe-oksijini emoyeni, nakweliphi na igumbi malunga ne-21%.
Iimaski ezingaphefumliyoubonelele nge-60% ukuya kwi-91% FIO2.Ukwenza oku, benza itywina empumlweni nasemlonyeni wakho.Eli tywina lidityaniswe neevalvu zendlela enye liqinisekisa ukuba uphefumla kuphela irhasi esuka kwitanki yeoksijini.
Ukusetyenziswa kwiiMaski ezingezizo zokuphefumla
Zininzi iindlela zokusombulula iingxaki zokuphefumla ezilunge ngakumbi kunokoiimaski ezingaphefumliyo. Iimaski ezingaphefumliyozidla ngokugcinelwa iimeko zonxunguphalo xa ufuna ioksijini eninzi ngaxeshanye.Ezinye zezi meko zikaxakeka ziquka ezi zilandelayo.
Ukwenzakala okubuhlungu.Nakuphi na ukwenzakala okukhulu esifubeni okanye emiphungeni kunokwenza kube nzima kuwe ukuba ufumane ioksijini eyaneleyo.Aimaski engeyiyo yokuphefumlainokukunceda ugcine uphefumla ngelixa kuthathwa amanyathelo angxamisekileyo ukuzinzisa imiphunga yakho.
Ukuphefumla umsi.Ukuphefumla umsi kungonakalisa kakhulu imiphunga yakho.Esinye isiphumo sokuphefumla umsi kukudumba kunye nokudumba kweendlela zakho zomoya.Aimaski engeyiyo yokuphefumlainceda ukunika ioksijini eyaneleyo ukukugcina uphefumla de ukudumba kuphele.
