Ngaba ngamanye amaxesha unengxaki yokuphefumla, ukuqina kwesifuba, okanye ukukhwehlela okungapheliyo? Ukuba ugqirha uthi kufuneka wenze uvavanyo lokujonga ukusebenza kwemiphunga yakho, mhlawumbi luvavanyo lwe-DLCO. Ngoko masithethe ngale nto namhlanje. Akukho nto yokoyika, luvavanyo olulula kakhulu.
Kalula nje, yintoni olu vavanyo lwe-DLCO?
Uvavanyo lwe-DLCO luvavanyo olukhethekileyo olulinganisa ukuba ioksijini ihamba kakuhle kangakanani ukusuka kwimiphunga yakho iye egazini lakho. Ngokuchanekileyo, lolunye lwezilingo ezininzi ezilinganisa ukusebenza kwemiphunga. Lunganika ugqirha wakho umbono olungileyo wokuba imiphunga yakho isempilweni kwaye isebenza kakuhle kangakanani.
Kolu vavanyo, kongezwa isixa esincinci kakhulu nesingenabungozi sekhabhoni monoxide emoyeni owuphefumlayo. Emva koko, isixa sekhabhoni monoxide efunxwa emiphungeni yakho iye egazini lakho siyalinganiswa. Oku kubizwa ngokuba yi "diffusing capacity yekhabhoni monoxide," okanye i-DLCO ngamafutshane.
Yintoni 'ukusasazwa'? Ibaluleke njani kuthi?
Khawucinge nje, xa siphefumla, ioksijini esemoyeni ingena emiphungeni yethu. Ukusuka apho, le oksijini iya kwiingxowa zomoya ezincinci kakhulu (i-alveoli) ezikwimiphunga. Ezi ngxowa zomoya zijikeleze ezi ngxowa zomoya zisasazeke njengenethiwekhi yemithambo yegazi emincinci kakhulu (ii-capillaries).
'Ukusasazwa' kubhekisa kwinkqubo apho ioksijini isasazeka khona kwimixokelelwane yomoya iye kwimithambo yegazi ize ixubane negazi. Kufana nokufaka ibhegi yeti kwikomityi yamanzi ashushu ize iti inyibilike emanzini. Ioksijini exubana negazi ngale ndlela ihamba emzimbeni wonke kwaye inike amandla kwiiseli zethu.
Ngoko ke, isantya kunye nokusebenza kakuhle kokufakwa kwale oksijini egazini kuxhomekeke kwizinto ezininzi :
- Indawo engaphezulu yeengxowa zomoya (i-alveoli) kwimiphunga yakho.
- Yilo ke inani legazi elikwimithambo yegazi emincinci (ii-capillaries) ezijikeleze iingxowa zomoya.
- Uxinzelelo lwe-hemoglobin, iproteni ethwala ioksijini egazini lakho.
- Ubukhulu be-membrane encinci phakathi kwengxowa yomoya kunye nomthambo wegazi.
- Nokuba kukho ulwelo olungafunekiyo ngaphakathi kwimibhobho yomoya.
Ukuba nayiphi na kwezi zinto iyatshintsha, ukuhanjiswa kweoksijini egazini kunokuphazamiseka. Yiloo nto uvavanyo lwe-DLCO lubalulekileyo ekufumaneni.
Kutheni ugqirha angacebisa olu vavanyo lwe-DLCO?
Kukho izizathu ezahlukeneyo zokuba ugqirha angakucela ukuba wenze olu vavanyo. Makhe sijonge ezona zizathu ziphambili.
| Isizathu sovavanyo | Ingcaciso elula |
|---|---|
| Ukufumana unobangela weempawu | Qonda ukuba ingaba imbangela yokwenyani yokuphefumla kwakho nzima nokukhohlela yingxaki yemiphunga. |
| Ukuvavanya umonakalo emiphungeni | Linganisa ukuba ungakanani umonakalo owenziweyo emiphungeni ngenxa yesifo okanye esinye isizathu. |
| Ukuchonga ezinye izifo zemiphunga | Olu vavanyo lusetyenziselwa ukufumanisa kwangethuba (ukuhlola) izifo ezithile zemiphunga. |
| Ngaphambi kotyando | Ngaphambi kotyando olukhulu, jonga ukuba imiphunga yakho isebenza kakuhle na. |
| Ukulinganisa impumelelo yonyango | Ukuba sele unyangelwa isifo semiphunga, jonga ukuba loo mayeza asebenza kangakanani. |
| Ukujonga imeko yesifo | Jonga ukuba imeko yezempilo yangoku iyaphucuka okanye iyawohloka. |
Kwenzeka ntoni xa ubhala uvavanyo?
Oku kulula kakhulu. Akukho sizathu sokuba woyike okanye ukhathazeke.
Ingcali eyenza uvavanyo iza kuqala ibeke ikliphu encinci empumlweni yakho. Yeka ukuphefumla ngaloo mpumlo. Emva koko iya kukuxelela ukuba ulandele la manyathelo:
1. Beka umlomo wakho kwisixhobo somlomo:Udinga ukufaka umlomo wakho emlonyeni oqhagamshelwe kumatshini uze uwuqinise ngokuqinileyo ukuze kungabikho moya uphumayo.
2. Phefumla ngokwesiqhelo: Okokuqala, phefumla ngokwesiqhelo, uphefumle kwaye ukhuphe umoya.
3. Phefumla nzulu: Okulandelayo, uxelelwa ukuba uphefumlele nzulu kangangoko unako.
4. Bamba umphefumlo wakho: Ngoku kufuneka ubambe umphefumlo wakho malunga nemizuzwana eli-10. Kulapho i-carbon monoxide ekumxube wegesi okhethekileyo ifunxwa egazini lakho.
5. Khupha umoya ngokukhawuleza: Emva koko, kufuneka ukhuphe umoya wakho wonke ungene kumatshini ngaxeshanye, ngokukhawuleza.
Lo matshini ulinganisa ubungakanani bekhabhoni monoxide eseleyo emoyeni owukhuphayo. Ukusuka apho, babala ukuba ingakanani into efunyenwe egazini lakho. Ungayiphinda le nkqubo kube kanye okanye kabini ukuze ufumane umlinganiselo ochanekileyo.
Eyona nto ibalulekileyo kukuba ubungakanani bekhabhoni monoxide esetyenzisiweyo kolu vavanyo buncinci kakhulu . Ayizukulimaza umzimba wakho nangayiphi na indlela. Ngoko ke ungakhathazeki ngayo.
Ngaba kufuneka ndilungiselele ngaphambi kovavanyo?
Ewe, ukuze ufumane iziphumo zovavanyo ezichanekileyo, kufuneka ulandele amanyathelo ambalwa alula. Ugqirha wakho uza kukuxelela ngale nto. Ngokwesiqhelo, la manyathelo ngala:
- Kuphephe ukutshaya iiyure ezi-4 ukuya kwezi-6 ngaphambi kovavanyo.
- Ukuba usebenzisa i-oxygen eyongezelelweyo, yiyeke imizuzu eli-10 ngaphambi kovavanyo (kuphela ukuba ungakwenza oko ngokukhuselekileyo).
- Musa ukwenza umthambo onzima ngaphambi kovavanyo.
Ungaziqonda njani iziphumo zovavanyo?
Iziphumo zovavanyo zinikwa njengepesenti. Oku kukuxelela ukuba amanqaku akho athelekiswa kangakanani namanqaku e-DLCO omele ube nawo, kuthathelwa ingqalelo izinto ezifana neminyaka yakho, ubude, kunye nesini.
| Isiphumo | Ixabiso (njengepesenti yexabiso elilindelekileyo) | Intsingiselo |
|---|---|---|
| Eqhelekileyo | Phakathi kwe-75% kunye ne-140% | Imiphunga yakho ifumana ioksijini eyaneleyo egazini lakho. |
| Incitshiswe kancinci | Phakathi kwama-60% kunye nama-75% | Ukutshintshiselana kweoksijini kuyaphazamiseka kancinci. Oku kungaba sisiqalo sengxaki ethile yempilo. |
| Incitshiswe kakhulu | Ngaphantsi kwama-40% | Ukutshintshiselana kweoksijini kuyaphazamiseka kakhulu. Oku kufuneka kuphandwe ngakumbi. |
Zithini izizathu zokwehla kwexabiso le-DLCO?
Ixabiso eliphantsi le-DLCO lithetha ukuba ioksijini ayidluliselwa kakuhle ukusuka kwimiphunga yakho ukuya egazini lakho. Oku kunokubangelwa ziimeko ezithile zemiphunga okanye zentliziyo. Umzekelo:
- Ukutshaya
- Iimeko ezifana neCOPD (iSifo esingapheliyo sokuVimba kwiPulmonary) kunye ne-Emphysema
- Izifo ezichaphazela izicubu zemiphunga, ezifana ne-sarcoidosis
- Izifo zentliziyo nemithambo yegazi - umzekelo, i-pulmonary embolism (PE), i-pulmonary arterial hypertension, ukusilela kwentliziyo okuxineneyo
- I-anemia
- Iingxaki zokuzikhusela komzimba - umzekelo, iLupus (SLE), iScleroderma
Ngaba ixabiso le-DLCO linganyuka?
Ewe, kwezinye iimeko, ixabiso le-DLCO linokuba phezulu kunokuba bekulindelwe. Ezi zilandelayo zizizathu zoku:
- Isifuba
- Ukutyeba kakhulu
- Ukuzilolonga ngaphambi kovavanyo
- Ukuhlala kwiindawo eziphakamileyo zeentaba
- Ukopha ngaphakathi emiphungeni
- Izifo zegazi ezifana ne-polycythemia vera
Ukuba iziphumo aziqhelekanga, yintoni oyenzayo emva koko?
Khumbula oku. Uvavanyo lwe-DLCO yinxalenye nje yephazili. Ugqirha wakho uza kudibanisa iziphumo zolu vavanyo kunye neempawu zakho, kunye neziphumo zezinye iimvavanyo zemiphunga, ezifana ne-spirometry, ukuze kufumaneke uxilongo lokugqibela.
Ukuba iziphumo aziqhelekanga, ungacelwa ukuba wenze olunye uvavanyo, mhlawumbi i-CT scan, ukuze ufumane unobangela ochanekileyo. Ngoko ungoyiki ukucinga ngeziphumo wedwa. Thetha nogqirha wakho ngayo kwaye ulandele icebiso lakhe.
Umyalezo Wokuya Ekhaya
- I-DLCO (Uvavanyo lokuSasazwa kweMiphunga) luvavanyo olukhuselekileyo nolulula olulinganisa indlela ioksijini edlula ngayo egazini lakho isuka kwimiphunga yakho.
- Oku kunceda ekufumaneni unobangela weempawu ezinje ngokuphefumla kancinci, ukuxilonga izifo zemiphunga, kunye nokulinganisa impumelelo yonyango.
- Kubalulekile ukuphepha ukutshaya kunye nokuzilolonga kakhulu ngaphambi kovavanyo ukuze ufumane iziphumo ezichanekileyo.
- Ukuba unemibuzo malunga neziphumo zovavanyo, ungoyiki ukubuza ugqirha wakho. Uza kukuchazela yonke into.
