Mayeso a DLCO (Lung Diffusion Testing) amayesa kuchuluka kwenikweni kwa mpweya womwe umadutsa kuchokera m'mapapo kupita ku magazi.

Kodi nthawi zina mumavutika kupuma, kulimba pachifuwa, kapena kutsokomola kosalekeza? Ngati dokotala wanena kuti muyenera kuchita mayeso kuti muwone momwe mapapo anu amagwirira ntchito, mwina ndi mayeso a DLCO. Tiyeni tikambirane za izi lero. Izi sizoyenera kuopa, ndi mayeso osavuta kwambiri.

Mwachidule, kodi mayeso a DLCO awa ndi otani?

Mayeso a DLCO ndi mayeso apadera omwe amayesa momwe mpweya umayendera kuchokera m'mapapo anu kupita m'magazi anu. Kunena zoona, ndi amodzi mwa mayeso angapo omwe amayesa momwe mapapo amagwirira ntchito. Angapatse dokotala wanu lingaliro labwino la momwe mapapo anu alili athanzi komanso ogwira ntchito bwino.

Mu mayeso awa, mpweya womwe mumapuma umachepa pang'ono komanso wopanda vuto lililonse, womwe umawonjezera carbon monoxide. Kenako, mpweya womwe umatengedwa kuchokera m'mapapo anu kupita m'magazi anu umayesedwa. Izi zimatchedwa "diffusing capacity ya carbon monoxide," kapena DLCO mwachidule.

Kodi 'Kufalikira' n'chiyani? Kodi n'kofunika bwanji kwa ife?

Tangoganizirani, tikamapuma, mpweya womwe uli mumlengalenga umapita m'mapapo mwathu. Kuchokera pamenepo, mpweyawu umapita ku matumba ang'onoang'ono a mpweya (alveoli) m'mapapo. Kuzungulira matumba a mpweya awa pali mitsempha yamagazi yopyapyala kwambiri (capillaries) yofalikira ngati ukonde.

'Kufalikira' kumatanthauza njira imene mpweya umafalikira kuchokera m'matumba a mpweya kupita m'mitsempha ya magazi ndikusakanikirana ndi magazi. Zili ngati kuyika thumba la tiyi m'kapu ya madzi otentha ndipo tiyiyo imasungunuka m'madzi. Mpweya umene umasakanikirana ndi magazi mwanjira imeneyi umayenda m'thupi lathu lonse ndipo umapatsa maselo athu mphamvu.

Chifukwa chake, liwiro ndi magwiridwe antchito omwe mpweya uwu umawonjezedwa m'magazi zimadalira zinthu zingapo :

• Malo ozungulira matumba a mpweya (alveoli) m'mapapu anu.
• Ndi momwe magazi alili m'mitsempha yaying'ono yamagazi (ma capillaries) ozungulira matumba a mpweya.
• Kuchuluka kwa hemoglobin, puloteni yomwe imanyamula mpweya m'magazi anu.
• Kukhuthala kwa nembanemba yopyapyala pakati pa thumba la mpweya ndi mtsempha wamagazi.
• Kaya pali madzi osafunikira mkati mwa malo otulutsira mpweya.

Ngati chimodzi mwa zinthuzi chisintha, mpweya woperekedwa m'magazi ukhoza kusokonekera. Ndicho chimene mayeso a DLCO ndi ofunikira kuti azindikire.

N’chifukwa chiyani dokotala angalimbikitse mayeso a DLCO awa?

Pali zifukwa zingapo zomwe dokotala angakupempheni kuti muyesedwe. Tiyeni tiwone zifukwa zazikulu.

Kodi chimachitika ndi chiyani mukalemba mayeso?

Izi n'zosavuta kwambiri. Palibe chifukwa choti muchite mantha kapena kuda nkhawa.

Katswiri amene adzachita mayesowa adzayamba waika kachidutswa kakang'ono pamphuno panu. Siyani kupuma kudzera mumphuno imeneyo. Kenako adzakuuzani kuti mutsatire izi:

1. Ikani pakamwa panu pa choyatsira pakamwa:Muyenera kuyika pakamwa panu pakamwa polumikizidwa ndi makina ndikulilimbitsa mwamphamvu kuti mpweya usatuluke.

2. Pumirani bwino: Choyamba, pumirani bwino, pumani ndi kutulutsa mpweya.

3. Pumirani mpweya wozama: Kenako, mukuuzidwa kuti mupumire mpweya wozama momwe mungathere.

4. Gwirani mpweya wanu: Tsopano muyenera kugwira mpweya wanu kwa masekondi pafupifupi 10. Apa ndi pamene mpweya wa carbon monoxide womwe uli mu mpweya wapadera umalowa m'magazi anu.

5. Pumirani mpweya mwachangu: Kenako, muyenera kutulutsa mpweya wanu wonse mu makina nthawi yomweyo, mwachangu.

Makinawa amayesa kuchuluka kwa mpweya wa carbon monoxide womwe umatsala mumlengalenga womwe mumatuluka. Kuchokera pamenepo, amawerengera kuchuluka kwa mpweya womwe walowa m'magazi anu. Mutha kubwereza izi kamodzi kapena kawiri kuti mupeze kuchuluka kolondola.

Kodi ndiyenera kukonzekera mayeso asanayambe?

Inde, kuti mupeze zotsatira zolondola za mayeso, muyenera kutsatira njira zosavuta zingapo. Dokotala wanu adzakuuzani za izi. Nthawi zambiri, izi ndi njira:

• Pewani kusuta fodya maola 4-6 musanayesedwe.
• Ngati mukugwiritsa ntchito mpweya wowonjezera, siyani kugwiritsa ntchito mphindi 10 musanayese mayeso (pokhapokha ngati mungathe kutero mosamala).
• Musachite masewera olimbitsa thupi olemera musanayese mayeso.

Kodi mungamvetse bwanji zotsatira za mayeso?

Zotsatira za mayeso zimaperekedwa ngati peresenti. Izi zimakuuzani kuchuluka kwa zigoli zanu poyerekeza ndi zigoli za DLCO zomwe muyenera kukhala nazo nthawi zonse, poganizira zinthu monga zaka zanu, kutalika kwanu, ndi jenda.

Kodi ndi zifukwa ziti zomwe zapangitsa kuti mtengo wa DLCO uchepe?

Kutsika kwa DLCO kumatanthauza kuti mpweya sukusamutsidwa bwino kuchokera m'mapapo kupita m'magazi. Izi zitha kuchitika chifukwa cha matenda ena a m'mapapo kapena a mtima. Mwachitsanzo:

• Kusuta
• Matenda monga matenda oletsa kupuma (COPD) ndi emphysema (Chronic Obstructive Pulmonary Disease).
• Matenda omwe amakhudza minofu ya m'mapapo, monga sarcoidosis
• Matenda a mtima ndi mitsempha yamagazi - mwachitsanzo, pulmonary embolism (PE), pulmonary arterial hypertension, congestive heart failure
• Kuchepa kwa magazi m'thupi
• Matenda a autoimmune - mwachitsanzo, Lupus (SLE), Scleroderma

Kodi mtengo wa DLCO ungakwere?

Inde, nthawi zina, mtengo wa DLCO ukhoza kukhala wokwera kuposa momwe amayembekezera. Izi zitha kukhala zifukwa izi:

• Mphumu
• Kunenepa kwambiri
• Kuchita masewera olimbitsa thupi musanayese mayeso
• Kukhala m'malo okwera mapiri
• Kutuluka magazi m'mapapo
• Matenda a magazi monga polycythemia vera

Ngati zotsatira zake sizili bwino, kodi muchita chiyani kenako?

Kumbukirani izi. Mayeso a DLCO ndi gawo limodzi chabe la chiwembu. Dokotala wanu adzaphatikiza zotsatira za mayesowa ndi zizindikiro zanu, ndi zotsatira za mayeso ena a m'mapapo, monga spirometry, kuti apeze matenda omaliza.

Ngati zotsatira zake sizili bwino, mungapemphedwe kuti muyesedwenso, mwina CT scan, kuti mudziwe chifukwa chenicheni. Choncho musaope kuganizira zotsatira zake nokha. Lankhulani ndi dokotala wanu za izi ndipo tsatirani malangizo ake.
