Sab hauv alveoli, cov pa nkag mus rau hauv koj cov ntshav, thiab cov pa roj carbon dioxide nkag mus rau hauv txoj hlab pa kom nqus tau. Nrog rau hnub nyoog, cov hnab cua me me no tuaj yeem ua tau poob lawv puab thiab elasticity . Lawv ua flatter, yog li ntawd yog tsawg cheeb tsam hauv lawv. Lawv kuj dhau los ua neeg nrawm dua, raws li koj cov phab ntsa alveolar tuab.
Yog li ntawd, dab tsi ua rau poob ntawm kev ywj pheej hauv lub ntsws?
Lub interstitial lub ntsws kab mob (ILDs) yog pab pawg kab mob uas ua rau lub ntsws puas tsuaj thiab thaum kawg fibrosis nrog poob ntawm elasticity ntawm lub ntsws . Lawv yog cov mob uas muaj tus yam ntxwv ua tsis taus pa. Lwm lo lus feem ntau siv rau ILDs yog " mob ntsws fibrosis ".
Qhov thib ob, ua li cas rau koj lub ntsws thaum koj muaj hnub nyoog? Raws li koj laj , kev hloov cuam tshuam koj lub ntsws nqaij, nqaij thiab pob txha, uas txhua yam cuam tshuam koj ua pa. Cov ntau npaum li cas ntawm huab cua koj lub ntsws can tuav- koj tag nrho lub ntsws peev - yog hais txog rau litres. Tom qab txog 35, lawv txoj haujlwm poob qis li koj laj thiab as a Qhov tshwm sim, ua tsis taus pa yuav maj mam ua nyuaj dua thaum lub sijhawm.
Ib yam li ntawd, koj tuaj yeem nug, lub ntsws puas tuaj yeem rov qab elasticity?
Elastic fibers tso cai rau cov lub ntsws kom nthuav dav thiab cog lus nrog ua pa. Cov lub ntsws ntawm cov neeg mob uas muaj mob obstructive mob ntsws kab mob (COPD) sim kho cov kab mob puas ntsoog puas tsuaj, qhov kev tshawb pom tshiab uas cuam tshuam nrog cov tswv yim qub ntawm kev muaj peev xwm ntawm cov neeg laus lub ntsws.
Lub ntsws puas muaj peev xwm txo nrog lub hnub nyoog?
Lub ntsws ntim nyob ntawm qhov loj ntawm lub cev, tshwj xeeb tshaj yog qhov siab. Tag nrho lub ntsws muaj peev xwm (TLC) kho rau hnub nyoog tseem tsis hloov pauv hauv lub neej. Ua haujlwm seem peev xwm thiab seem ntim nce nrog hnub nyoog , ua rau qis dua muaj peev xwm tseem ceeb . Kev sib pauv roj hauv lub ntsws tshwm sim thoob plaws alveolar capillary membrane.

Vim Li Cas Lub Peev Xwm Muaj Peev Xwm Tseem Ceeb? Lub ntsws muaj peev xwm kwv yees kev noj qab haus huv thiab kev nyob ntev. Qhov no txhais tau tias koj muaj hnub nyoog laus dua, nws nyuaj rau koj lub ntsws ua pa thiab tuav huab cua. Thaum peb nqus pa tsawg dua, peb lub cev thiab cov hlwb tseem tau txais cov pa oxygen tsawg dua, yuam peb lub siab ua haujlwm nyuaj kom nqus cov pa thoob plaws lub cev

Emphysema yog ib yam mob uas ua rau mob hauv lub ntsws ua rau nthuav dav thiab puas tsuaj ntawm alveoli. Ntxiv nrog rau qhov poob ntawm alveoli, lub cellular phab ntsa ntawm cov pa hnab uas nyob twj ywm pib harden thiab poob lawv elasticity. Qhov no ua rau nws nyuaj rau tshem tawm huab cua los ntawm lub ntsws (ib yam mob hu ua cua tshuab)
