Ngaba wakha wambona umntu onengxaki yokuphefumla aze angeniswe kwigumbi lonyango oluphezulu (ICU) esibhedlele? Ngamanye amaxesha oogqirha basebenzisa iindlela ezahlukeneyo ukunceda abantu abanjalo ukuba baphefumle. Lo mxube wegesi okhethekileyo osetyenziswa kwiimeko ezingxamisekileyo ubizwa ngokuba yiHeliox. Eli gama lisenokuba litsha kuwe. Ngoko masithethe ngalo namhlanje.
Yintoni iHeliox?
Ngamafutshane, iHeliox ngumxube wegesi okhethekileyo owenziwe ngokudibanisa iigesi ezimbini, ihelium kunye neoksijini, kunye. Inikwa izigulana ezinengxaki yokuphefumla, ingakumbi kwiimeko ezingxamisekileyo.
Ngoku usenokuba ucinga, "Sihlala siphefumla ioksijini, akunjalo? Kutheni kufuneka songeze i-helium koku?" Umbuzo omhle. Makhe sibone ukuba yintoni isizathu.
Umoya esiwuphefumlayo ngokuqhelekileyo umalunga ne-21% yeoksijini kunye ne-78% yeoksijini. Eminye yenziwe ngezinye iigesi. Kwanasesibhedlele, xa umntu enikwa ioksijini, uhlala enikwa umxube weoksijini kunye ne-nitrogen. Nangona kunjalo, i-helium yigesi ekhaphukhaphu kakhulu kune-nitrogen. Khawuthelekelele ibhaluni egcwele i-helium enyukayo xa uyiyeka, akunjalo? I-Helium ilula kakhulu.
Ngoko ke, xa iindlela zomoya zomntu zidumbile kwaye zixinene, xa ioksijini ixutywe nale gesi ye-helium ekhaphukhaphu, loo mxube wegesi unokuhamba ngokulula kwiindlela zomoya ezixineneyo kwaye ungathinteleki kangako ukuya emiphungeni. Oku kunciphisa kakhulu umgudu ofunekayo ukuze umntu aphefumle.
Ukuchaneka, igesi ye-helium yenza kube lula ukuba ioksijini ingene emiphungeni. Njengenitrogen, i-helium yigesi engasebenziyo engasabelani nemizimba yethu. Oku kuthetha ukuba umzimba uthatha kuphela ioksijini ekumxube kwaye ukhuphe i-helium ngomoya ophumayo.
Isetyenziswa nini iHeliox?
IHeliox ayisiyonto yokuphelisa zonke iingxaki. Nangona kunjalo, inokunceda ukuzinzisa imeko yesigulana ngokusinceda siphefumle lula de kube kusebenze ezinye iindlela zonyango kwaye imeko yaso iphucuke. Nazi ezinye zeemeko apho oogqirha banokusebenzisa olu nyango.
| Imeko yezonyango | Ingcaciso elula |
|---|---|
| I-Acute Respiratory Distress Syndrome (ARDS) | Imeko engxamisekileyo apho imiphunga yonakele kakhulu, izaliswe lulwelo, kwaye ingakwazi ukuphefumla yodwa. |
| Ukuvalwa kwendlela yomoya | Xa indlela yomoya ivalwe sisimila, into yangaphandle (umz. iqhekeza lokutya), okanye ngesinye isizathu. |
| Imeko yesifuba esimandundu (Isimo se-Asthmaticus) | Uhlaselo lwesifuba esibi kakhulu kangangokuba asinakulawulwa nokuba kusetyenziswe unyango oluqhelekileyo, kwaye lunokuba yingozi ebomini. |
| Isifo semiphunga esingapheliyo (i-COPD) | Xa ubunzima bokuphefumla bukhula ngequbuliso ngenxa yesifo esingapheliyo sokuvaleka kwemiphunga. |
| Isifo sokudakumba | Xa abantu abantywila emanzini anzulu bevela ngequbuliso, amaqamza e-nitrogen ayenzeka egazini labo ngenxa yotshintsho kuxinzelelo lomzimba. Oku kwaziwa ngokuba “zii-bends.” |
| I-Stridor emva kokukhupha i-extubation | Emva kokuba ifakwe ityhubhu yokuncedisa ekuphefumleni, kwaye isusiwe, umqala uyadumba kwaye wenze isandi esiqatha, 'groo-groo' xa uphefumla. |
Lunikwa njani olu nyango?
Le gesi yeHeliox inikwa kuphela isigulana esisesibhedlele, phantsi kweliso likagqirha. Ugqirha umisela eyona ndlela ilungileyo ngokusekelwe kwimeko yesigulana.
Ezi ndlela zilandelayo zisetyenziswa kakhulu:
- Nge-Ventilator: Ukuba isigulana asikwazi ukuphefumla sodwa, lo mxube unganikwa ngelixa isigulana singazi nto kwaye siphefumla ngomatshini.
- Ngemaski yobuso: Ukuba isigulana sisezingqondweni, le gesi inokunikezelwa ngemaski eqinisiweyo nengavuziyo.
- Nge-cannula yempumlo: Kwezinye iimeko, oku kunikwa ngetyhubhu encinci efakwe empumlweni nganye.
Ugqirha okanye ingcali yokuphefumla iya kutshintsha umlinganiselo we-helium kunye ne-oxygen kuxhomekeke kubungakanani be-oxygen efunekayo kwisigulana. Imixube eqhelekileyo esetyenziswayo yile:
- I-70% ye-helium / i-30% yeoksijini
- I-60% ye-helium / i-40% yeoksijini
Ziziphi iingenelo kunye neengxaki zonyango lweHeliox?
Njengalo naluphi na unyango, olu lunezibonelelo kunye neengxaki.
Iingenelo
Iingenelo ezimbini eziphambili zoku zezi:
1. Kunciphisa umgudu ofunekayo ukuze umntu aphefumle: Umzimba unokuphefumla lula ngaphandle kokwenza umgudu omkhulu. Oku kusindisa amandla omguli okulwa nesifo.
2. Inciphisa ukuvaleka komoya ongena emiphungeni: Xa iindlela zomoya zivalekile, kukho ukuvaleka okukhulu komoya oqhelekileyo. Nangona kunjalo, ngenxa yokukhanya kweHeliox, loo kuvaleka kuyancitshiswa kwaye umoya uhamba lula.
Iingxaki
Eyona ngxaki okanye umceli mngeni omkhulu woku kukuba kufuna izixhobo ezikhethekileyo kunye nabasebenzi abaqeqeshwe kakuhle ukubonelela ngolu nyango.
Ukulinganiswa kunye nokubekwa kwezixhobo zoomatshini be-oksijini kunokutshintsha xa kunikwa i-heliox. Oku kungenxa yokuba ubuninzi be-helium bahlukile kobo be-nitrogen. Ke ngoko, oogqirha kunye nabasebenzi bobuhlengikazi kufuneka bazi kakuhle ezi nguqu baze balungise izixhobo ngokuchanekileyo. Kodwa ukuba uyazi oku, i-heliox lunyango olukhuselekileyo kakhulu.
Umyalezo Wokuya Ekhaya
- IHeliox ngumxube wehelium kunye neoksijini. Isetyenziswa kwiimeko ezingxamisekileyo apho kunzima ukuphefumla.
- Ngenxa yokuba igesi ye-helium ekule nto ilula kakhulu, inceda ukuhambisa ioksijini ngokulula ukuya emiphungeni ngokusebenzisa iindlela zomoya ezivuvukileyo nezixineneyo.
- Oku akusinyangi isifo ngokuthe ngqo. Nangona kunjalo, kunceda umguli ukuba aphefumle lula kwaye kuzinzise imeko de kusebenze amanye amayeza kunye nonyango.
- Olu nyango lunikwa esibhedlele kuphela, phantsi kweliso elibukhali likagqirha. Luza kunikwa kuphela xa ugqirha wakho egqiba kwelokuba kuyimfuneko.
- Oku kufuna izixhobo ezikhethekileyo kunye noqeqesho, ngoko ke ayizizo zonke izibhedlele ezinokuba nale ndawo.
