Khawuthelekelele umntu osondeleyo kuwe, mhlawumbi umntwana omncinci one-asthma okanye umntu omdala, ngequbuliso akakwazi ukuphefumla, abe nesithuthwane, aze afuthaniseleke. Besiya koyika kangakanani ngexesha elinjalo? Ngoko ke, namhlanje sithetha ngonyango olukhethekileyo olunokusetyenziswa ngoogqirha kwizibhedlele xa kukho imeko engxamisekileyo. Oku kubizwa ngokuba yiHeliox. Kukho amaxesha apho olu nyango lunokuba lunyango olusindisa ubomi.
Ngamafutshane, yintoni iHeliox?
IHeliox ngumxube weegesi ezimbini, ihelium kunye neoksijini. Isetyenziswa ngabasebenzi bezempilo, oko kukuthi, oogqirha, ukunyanga izigulana ezinengxaki yokuphefumla enzima, ingakumbi kwiimeko ezingxamisekileyo. Umsebenzi wayo ophambili kukunciphisa umgudu umzimba omele uwenze ukuze uphefumle.
Ngoku khangela, umoya esiwuphefumlayo umalunga ne-21% yeoksijini kwaye malunga ne-78% yenitrogen. Kwanasesibhedlele, ioksijini inikwa njengeoksijini ecocekileyo okanye ixutywe nenitrogen. Kodwa apha, igesi ye-helium inamandla akhethekileyo. I-Helium yigesi ekhaphukhaphu kakhulu kune-nitrogen.
Ukuze siqonde oku, masithathe umzekelo omncinci. Khawucinge ukuba indlela yakho yomoya (umoya) inciphile ngenxa yomkhuhlane, i-asthma, okanye esinye isizathu. Kufana nombhobho wamanzi ovalekileyo. Ngoku, ukuba uzama ukutyhala ulwelo oluqinileyo, njengobusi, kulo mbhobho uvalekileyo, ingaba nzima kangakanani? Kuya kufuneka ufake uxinzelelo oluninzi. Igesi ye-nitrogen inzima kancinci. Kodwa ukuba uzama ukutyhala ulwelo olukhaphukhaphu olufana namanzi kuloo mbhobho? Ihamba lula kakhulu. Igesi ye-Helium ilula njengamanzi. Ke ngoko, i-helium inceda ukuthwala ioksijini ngokulula kwiindlela zomoya ezivalekileyo nezinciphileyo ukuya emiphungeni.
IHelium, njengenitrogen, "yigesi engasebenziyo". Oko kuthetha ukuba ayisebenzi nezinye izinto emzimbeni. Umzimba uthatha ioksijini kuphela kulo mxube uze uphefumle ihelium kwakhona. Oko kuthetha ukuba ihelium "sisithuthi" nje esithwala ioksijini ukuya emiphungeni.
Isetyenziswa nini iHeliox?
Into ebalulekileyo kukuba iHeliox ayilonyango lwesifo. Kunoko, yinkxaso enikwayo ukugcina isigulana sizinzile de kubekho ezinye iindlela zonyango (umz., amayeza e-asthma) ezisebenzayo kwaye imeko yesigulana iphucuke. Kufana nokunika umntu i-buoy xa etshona. Inceda ukusindisa ubomi bakhe, ngelixa elinde iqela lokuhlangula ukuba lifike. Itheyibhile engasezantsi ibonisa ezinye zeemeko eziphambili apho iHeliox isetyenziswa khona.
| Imeko | Ingcaciso elula |
|---|---|
| Uhlaselo olumandundu lombefu (Status Asthmaticus) | Xa iindlela zomoya ziba mxinwa kakhulu kwimeko enzima yesifuba engalawulwayo ngonyango oluqhelekileyo kwaye inokuba yingozi ebomini. |
| Ukuvalwa kwendlela yomoya | Xa indlela yomoya ivalwe sisimila okanye into ethile (umz. iqhekeza lokutya) ibambeka. |
| Ukwanda kwe-COPD (isifo esingapheliyo sokuvaleka kwemiphunga) | Xa izigulane ze-COPD zinengxaki enkulu yokuphefumla ngenxa yesizathu esifana nosulelo. |
| I-ARDS (i-Acute Respiratory Distress Syndrome) | Imeko apho imiphunga yonakala ngenxa yosulelo olunzima okanye iingozi kwaye izaliswe lulwelo kangangokuba ukuphefumla kungenzeki. |
| I-stridor emva kokukhupha umoya | Ukuba ityhubhu yokuphefumla isusiwe, njengasemva kotyando, kwaye kukho isandi sokuphefumla xa uphefumla ngenxa yokudumba emqaleni. |
| Ukugula Kokunciphisa Uxinzelelo ("Iibhendi") | Xa abantu abantywila emanzini anzulu bevela ngokukhawuleza, igesi yenitrogen eqokelelene egazini labo ijika ibe ngamaqamza. |
Lunikwa njani olu nyango?
Kukho iindlela ezahlukeneyo zokusebenzisa unyango lweHeliox. Ugqirha uya kugqiba ngokwemeko yesigulana.
- Nge-Ventilator: Le ndlela isetyenziswa xa isigulana singekho zingqondweni kwaye ukuphefumla kubonelelwa ngumatshini ukuba asikwazi ukuphefumla sodwa.
- Ngemaski yoBuso:Ifakwa ngemaski ekhethekileyo efanela impumlo nomlomo wesigulana.
- Nge-cannula yempumlo: Inikwa ngetyhubhu encinci ebekwe phantsi kwempumlo.
Ugqirha okanye ingcali yokuphefumla iya kutshintsha ipesenti ye-helium kunye ne-oxygen ngokweemfuno zesigulana. Imixube eqhelekileyo esetyenziswayo yi-70% ye-helium/30% ye-oxygen okanye i-60% ye-helium/40% ye-oxygen.
Zithini iingenelo kunye neengxaki zoku?
Iingenelo
Eyona nzuzo inkulu yoku, njengoko benditshilo ngaphambili, kukuba kunciphisa umgudu umzimba omele uwusebenzise ukuze uphefumle. Xa sinengxaki yokuphefumla, izihlunu zethu zesifuba nezesisu zisebenza nzima kakhulu. Oku kunciphisa loo mgudu kwaye kunika umzimba ithuba lokuphumza. Kukwanciphisa nokuvalwa kwendlela yokuhambisa ioksijini kwiindlela zomoya ezixineneyo.
Iingxaki
Eyona ngxaki okanye umceli mngeni mkhulu kukuba olu nyango lufuna izixhobo ezikhethekileyo kunye nabasebenzi abaqeqeshiweyo ukuze balawule. Ukulinganiswa kunye nokuseta koomatshini abaqhele ukusetyenziswa ukuphatha ioksijini kunokutshintsha xa kusetyenziswa i-heliox. Ke ngoko, oogqirha kunye nabasebenzi kufuneka bazi ngokupheleleyo ngolu tshintsho.
Kodwa njengesigulana, awunasizathu sokoyika oku. Oogqirha bayazi kakuhle le nto, kwaye lo gama nje olu nyango lunikwa phantsi kweliso labo, umngcipheko kwisigulana uphantsi kakhulu.
Olu nyango lunikwa de isigulane sikwazi ukuphefumla kakuhle ngokwaso okanye sinokudluliselwa kunyango lwe-oksijini oluqhelekileyo. Ukuchacha ngokukhawuleza kwenzeka kuxhomekeke ekubeni imeko engaphantsi (umz., i-asthma) ilawulwa ngokukhawuleza kangakanani.
Umyalezo Wokuya Ekhaya
- IHeliox ngumxube we-helium kunye negesi yeoksijini. Isetyenziswa ezibhedlele xa kukho ubunzima obukhulu bokuphefumla.
- Oku kusebenza ngokunceda ukuhambisa ioksijini ngokulula kwiindlela zomoya ezinciphileyo ukuya emiphungeni, njengoko igesi ye-helium ilula kune-nitrogen.
- Olu asilonyango lwesifo, kodwa lunyango lwexeshana oluxhasayo olunika isiqabu kwisigulana xa kukho imeko engxamisekileyo, efana ne-asthma enzima okanye ukuvaleka kwendlela yomoya.
- Oku kubonelelwa phantsi kweliso likagqirha, ngabasebenzi abaqeqeshiweyo abasebenzisa izixhobo ezikhethekileyo.
- Ukuba wena okanye umntu omaziyo unengxaki yokuphefumla enzima, eyona nto ingcono onokuyenza ngoko nangoko kukubasa kwiYunithi yoNyango oluNgxamisekileyo (ETU) yesibhedlele esikufutshane, apho oogqirha baya kubonelela ngonyango olufunekayo.
