DLCO test (Lung Diffusion Testing) hian lung atanga thisen a oxygen kal zat dik tak a teh a ni.

A châng chuan thawk harsa i nei em, i rilru a na a, i khuh reng bawk em? Doctor-in i lung hnathawh enfiah nan test i tih a ngai a tih chuan DLCO test a ni mai thei. Chuvangin vawiin hian he thu hi han sawi mai ila. Hei hi hlauh tur a ni lo, test awlsam tak a ni.

A awlsam zawngin sawi ila, he DLCO test hi eng nge ni?

DLCO test hi special test a ni a, i lung atanga i thisenah oxygen a kal that dan tehna a ni. A dik tak chuan lung hnathawh tehna test hrang hrang zinga pakhat a ni. I doctor hnenah i lung a hrisel leh efficient dan tur ngaihtuahna tha tak a pe thei a ni.

He test-ah hian i thawk boruakah hian carbon monoxide tlem tak, hlauhawm lo tak a dah tel a ni. Tichuan, i lung atanga i thisena carbon monoxide lut zat chu an teh thin. Hei hi "carbon monoxide diffusing capacity" emaw, a tawi zawngin DLCO emaw an ti a ni.

‘Diffusion’ chu eng nge ni? Engtin nge kan tan a pawimawh?

Ngaihtuah teh, kan thawk chhuah hian boruaka oxygen chu kan lung chhungah a lut a. Chuta tang chuan he oxygen hi lung chhunga boruak bawm (alveoli) te tak te takah a kal a. Heng boruak bawm vel hi thisen kalna kawng (capillaries) te tak te network ang maiin an inzar pharh a.

‘Diffusion’ tih hian chu boruak bawm atang chuan oxygen chu thisen kalna kawngah a darh a, thisen nen a inhmeh tawn dan a kawk a ni. Tui lum no khatah tea bag dah a, tea chu tuiah a hmin ang mai a ni. Hetianga thisen nena inpawlh oxygen hian kan taksa pum puiah a fang kual a, kan cell-te tan chakna a pe a ni.

Chuvangin, he oxygen hi thisenah a dah chak dan leh a hman tangkai dan hi thil engemaw zat ah a innghat a ni:

• I lung chhunga air sacs (alveoli) awmte surface area.
• Chutiang zat chu air sacs vel thisen kalna kawng te tak te (capillaries) ah hian a awm a ni.
• I thisena oxygen phurtu protein, hemoglobin concentration.
• Air sac leh thisen kalna inkara membrane te tak te thickness.
• Air vents chhungah a tul lova liquid buildup a awm leh awm loh.

Heng zinga pakhat tal a inthlak chuan thisenah oxygen pekna a tichhe thei a ni. Chu chu DLCO test-in a hriatchhuahna atana pawimawh tak chu a ni.

Engvangin nge doctor chuan he DLCO test hi a rawt ang?

Doctor-in he test hi tihsak tura a tih chhan hi chhan hrang hrang a awm. A chhan berte han thlir ila.

Test i tih hian eng nge thleng?

Hei hi a awlsam hle. I hlauh tur leh i lungkham chhan tur a awm lo.

Test titu technician chuan i hnar-ah clip te tak te a dah hmasa ang. Chu hnar hmanga thawk chu bansan rawh. Tichuan heng step te hi zawm turin an hrilh ang che:

1. I hmui chu hmuiah dah la:I hmui chu machine nena inzawm mouthpiece-ah dah la, boruak a chhuah loh nan khauh taka i khauh a ngai a ni.

2. Thawk dan pangngai: A hmasa berin thawk dan pangngaiin thawk la, thawk la, thawk la.

3. Thâwk la rawh: A dawtah chuan a tam thei ang ber thawk la turin an hrilh che a ni.

4. Thâwk kha vawng tlat rawh: Tunah chuan second 10 vel i thaw kha i vawn tlat a ngai tawh. Hei hi gas special mixture-a carbon monoxide awm chu i thisenah a lut a ni.

5. Thâwk chhuah vat rawh: Tichuan, i thawk zawng zawng chu vawi khatah, rang takin machine chhungah i chhuah vek a ngai a ni.

Machine hian i thawk chhuah boruak a carbon monoxide awm zat a teh thin. Chuta tang chuan i thisenah engzat nge a luh tawh tih an chhut chhuak thin. Chhiar dik tak hmuh theih nan he thil hi vawi khat emaw vawi hnih emaw i ti leh thei bawk.

Test hmain inbuatsaih a ngai em?

Ni e, test result dik tak hmuh tur chuan step awlsam tlemte i zawm a ngai a ni. Hemi chungchang hi i doctor chuan a hrilh ang che. A tlangpuiin, hengte hi a hnuaia mi ang hian a ni:

• Test hma darkar 4-6 chhungin meizuk loh tur.
• Supplemental oxygen i hman chuan test hma minute 10-ah tihtawp tur a ni (him taka i tih theih chuan chauh).
• Test hmain exercise hahthlak tak tak nei suh.

Test result hi engtin nge kan hriatthiam ang?

Test result hi percentage anga pek a ni. Hei hian i score chu i neih tlangpui tur DLCO score nen a khaikhin chuan engzat nge a nih tih a hrilh che a, i kum, i san zawng leh i mipa leh hmeichhia te pawh ngaihtuah tel a ni.

DLCO hlutna tlahniam chhante chu engte nge ni?

DLCO value hniam chuan i lung atanga i thisenah oxygen a transfer tha lo tihna a ni. Hei hi lung emaw thinlung lam natna thenkhat vang a ni thei. Entir nan:

• Meizial zuk
• COPD (Chronic Obstructive Pulmonary Disease) leh Emphysema ang chi natna te
• Lung tissue tichhe thei natna, sarcoidosis ang chi te
• Lung leh thisen kalna kawng natna - entirnan, pulmonary embolism (PE), pulmonary arterial hypertension, congestive heart failure
• Thisen tlakchhamna (Anaemia).
• Autoimmune disorder - entirnan, Lupus (SLE), Scleroderma te hi a ni

DLCO hlutna hi a pung thei ang em?

Ni e, a then phei chuan DLCO value hi beisei aia sang a ni thei. A hnuaia mite hi a chhan chu a ni thei ang:

• Asthma natna a ni
• Thau lutuk
• Test hmaa exercise lak
• Tlang sang hmuna awm
• Lung chhunga thisen chhuak
• Thisen natna chi hrang hrang, polycythemia vera

Results a dik lo a nih chuan eng nge i tih leh ang?

Hei hi hre reng ang che. DLCO test hi puzzle pakhat chauh a ni. I doctor chuan he test result leh i symptoms te, leh lung test dang, spirometry ang chi result te chu a rawn dah khawm ang a, a tawp berah chuan diagnosis a thleng ang.

Results a dik lo a nih chuan a chhan dik tak hriat tumin test dang, CT scan pawh ni thei, tih belh leh turin an ti mai thei che a ni. Chuvangin a result chauh ngaihtuah hlau suh. I doctor nen sawiho la, a thurawn zawm rawh.
