DLCO sɔhwɛ (Lung Diffusion Testing) no susuw mframa pa dodow pɔtee a efi ahurututu mu kɔ mogya no mu.

So ɛtɔ mmere bi a, ɛyɛ den ma wo sɛ wobɛhome, wo koko mu yɛ wo yaw, anaasɛ wofefe bere nyinaa? Sɛ oduruyɛfo bi ka sɛ ɛsɛ sɛ woyɛ nhwehwɛmu de hwɛ sɛnea w’ahurututu yɛ adwuma a, ebia ɛyɛ DLCO nhwehwɛmu. Enti momma yɛnka eyi ho asɛm nnɛ ara kwa. Eyi nyɛ biribiara a ɛsɛ sɛ wosuro, ɛyɛ sɔhwɛ a ɛyɛ mmerɛw yiye.

Sɛ yɛbɛka no tiawa a, dɛn ne DLCO sɔhwɛ yi?

DLCO sɔhwɛ no yɛ sɔhwɛ titiriw bi a ɛkyerɛ sɛnea oxygen fi w’ahurututu mu kɔ wo mogya mu yiye. Sɛ yɛbɛka no pɛpɛɛpɛ a, ɛyɛ nhwehwɛmu dodow bi a wɔde kyerɛ ahurututu mu dwumadi no mu biako. Ebetumi ama wo duruyɛfo anya sɛnea w’ahurututu no wɔ apɔwmuden na ɛyɛ adwuma yiye no ho adwene pa.

Wɔ sɔhwɛ yi mu no, wɔde carbon monoxide kakraa bi pɛ a asiane biara nni ho ka mframa a wohome no ho. Afei, wosusuw carbon monoxide dodow a efi w’ahurututu mu kɔ wo mogya mu. Wɔfrɛ eyi sɛ "tumi a ɛma carbon monoxide trɛw," anaasɛ DLCO tiawa.

Dɛn ne ‘Ntrɛwmu’? Ɔkwan bɛn so na ɛho hia yɛn?

Fa no sɛ, sɛ yɛhome a, mframa pa a ɛwɔ mframa mu no kɔ yɛn ahurututu mu. Efi hɔ no, oxygen yi kɔ mframa kotoku nketewa paa (alveoli) a ɛwɔ ahurututu no mu no mu. Mogya ntini (capillaries) a ɛyɛ fɛ yiye a ɛtrɛw te sɛ asau atwa mframa kotoku yi ho ahyia.

‘Diffusion’ kyerɛ ɔkwan a oxygen fa so trɛw fi saa mframa kotoku no mu kɔ mogya ntini no mu na ɛne mogya no fra. Ɛte sɛ nea wode tii kotoku bɛhyɛ nsu a ɛyɛ hyew kuruwa mu na tii no apete nsu no mu. Oxygen a ɛfrafra mogya no mu wɔ saa kwan yi so no fa yɛn nipadua nyinaa mu na ɛma yɛn nkwammoaa no ahoɔden.

Enti, ahoɔhare ne sɛnea wɔde oxygen yi bɛka mogya no ho no gyina nneɛma pii so:

• Mframa kotoku (alveoli) a ɛwɔ w’ahurututu mu no ani.
• Saa na mogya dodow a ɛwɔ mogya ntini nketenkete (capillaries) a atwa mframa kotoku no ho ahyia no mu.

• Sɛ́ ebia nsu a ɛho nhia aboaboa ano wɔ mframa a wɔde fa mu no mu anaa.

Sɛ nneɛma yi mu biara sesa a, mframa pa a ɛkɔ mogya no mu no betumi asɛe. Ɛno ne nea DLCO sɔhwɛ no ho hia na ama wɔahu.

Dɛn nti na oduruyɛfo bi bɛkamfo DLCO nhwehwɛmu yi akyerɛ?

Nneɛma pii nti na oduruyɛfo betumi aka akyerɛ wo sɛ yɛ nhwehwɛmu yi. Momma yɛnhwɛ nneɛma atitiriw a enti ɛte saa.

Sɛ woyɛ sɔhwɛ no a, dɛn na ɛba?

Eyi yɛ mmerɛw yiye. Biribiara nni hɔ a enti ɛsɛ sɛ wusuro anaa wohaw wo ho.

Mfiridwumayɛfo a ɔbɛyɛ sɔhwɛ no bedi kan de biribi ketewaa bi ahyɛ wo hwene so. Gyae ahome a wobɛfa saa hwene no mu. Afei wɔbɛka akyerɛ wo sɛ di anammɔn yi akyi:

So ɛsɛ sɛ misiesie me ho ansa na sɔhwɛ no aba?

Yiw, sɛ wubenya sɔhwɛ no mu aba a edi mu a, ɛsɛ sɛ wudi anammɔn kakraa bi a ɛnyɛ den akyi. Wo duruyɛfo bɛka eyi ho asɛm akyerɛ wo. Mpɛn pii no, eyinom ne anammɔn ahorow:

Dɛn ne nneɛma a ɛma DLCO bo so tew?

DLCO dodow a ɛba fam kyerɛ sɛ wɔmfa oxygen mfi w’ahurututu mu nkɔ wo mogya mu yiye. Eyi betumi afi ahurututu anaa komayare ahorow bi mu aba. Nhwɛsoɔ:
