Lung Volume vs Lung Peev
Ua pa tuaj yeem hais tau yooj yim raws li tus txheej txheem ntawm kev noj cov pa thiab tshem cov pa roj carbon dioxide los ntawm cov hlwb ntawm lub cev. Kev sib pauv roj thiab kev ua pa ntawm tes yog qhov tseem ceeb ntawm nws. Tib neeg txoj kev ua pa yog tsim los rau cov txheej txheem ntawm kev sib pauv roj. Kev ua pa thiab ua pa, hloov roj thiab thauj, cov ntshav ntws mus rau lub ntsws thiab tswj kev ua pa yog lub luag haujlwm tseem ceeb ntawm tib neeg txoj kev ua pa. Lub ntsws ua lub luag haujlwm tseem ceeb ntsig txog kev ua pa. Qhov kom muaj nuj nqis ntawm cov pa hauv lub ntsws tuaj yeem muab faib ua ntau qhov ntim thiab muaj peev xwm. Lub ntsws muaj peev xwm yog qhov sib npaug lossis sib xyaw ntawm ob lossis ntau lub ntsws ntim. Kev ntsuas lub ntsws ntim yog ib qho tseem ceeb kom nkag siab txog kev ua haujlwm ntawm lub ntsws thiab cov kab mob. Qee qhov ntim thiab qhov muaj peev xwm tuaj yeem ntsuas ncaj qha los ntawm qhov yooj yim spirometry.
Lub ntsws Volume yog dab tsi?
Lub ntsws ntim tuaj yeem faib ua Inspiratory Reserve Volume (IRV), Tidal Volume (TV), Expiratory Reserve Volume (ERV), thiab Residual Volume (RV). Inspiratory Reserve Volume (IRV) yog qhov ntim ntxiv ntawm huab cua uas tuaj yeem nqus tau nrog kev siv zog tshaj plaws tom qab kev tshoov siab ib txwm muaj. Qhov nruab nrab IRV hauv cov txiv neej yog 3.3 L, thiab hauv cov poj niam nws yog 1.9 L. Tidal Volume (TV) yog qhov ntim ntawm huab cua ua pa ib txwm nyob hauv thiab tawm yam tsis muaj kev siv zog. Qhov no tuaj yeem nce ntxiv nrog kev tawm dag zog lossis kev ua si. Qhov nruab nrab TV hauv cov txiv neej yog 0.5 L, thiab hauv cov poj niam, nws yog 0.5 L. Expiratory Reserve Volume (ERV) yog qhov ntim ntxiv ntawm huab cua uas tuaj yeem nqus tau yuam kev tom qab exhalation. Qhov nruab nrab ERV hauv cov txiv neej yog 1.0 L thiab rau cov poj niam yog 0.7 L. Residual Volume (RV) yog qhov ntim ntawm cov pa tawm hauv lub ntsws thaum kawg ntawm qhov kawg (lub ntsws tsis tuaj yeem ua rau tag nrho). Qhov nruab nrab RV ntawm cov txiv neej yog 1.2 L thiab rau cov poj niam yog 1.1 L.
Lub ntsws muaj peev xwm yog dab tsi?
Lub ntsws muaj peev xwm tuaj yeem faib ua Inspiratory Capacity (IC), Functional Residual Capacity (FRC), Vital Capacity (VC), thiab Total Lung Capacity (TLC). Inspiratory Capacity (IC) yog tag nrho ntawm Tidal Volume thiab Inspiratory Reserve Volume (VT + IRV). Qhov nruab nrab IC nyob rau hauv cov txiv neej yog 3.8 L, thiab cov poj niam, nws yog 2.4 L. Functional Residual Capacity (FRC) suav nrog cov ntim ntim tas mus li ntxiv rau qhov seem seem (ERV + RV). Qhov no yog tag nrho cov huab cua sab laug nyob rau hauv lub ntsws tom qab ib txwm, so tas sij hawm. Qhov nruab nrab FRC hauv cov txiv neej yog 2.2 L, thiab hauv cov poj niam, nws yog 1.8 L. Qhov tseem ceeb muaj peev xwm (VC) txhais tau tias tag nrho cov khoom siv ntawm lub ntsws uas yog nyob rau hauv kev yeem tswj hwm. Qhov nruab nrab VC nyob rau hauv cov txiv neej yog 4.8 L, thiab nyob rau hauv cov poj niam, nws yog 3.1 L. Tag nrho lub ntsws muaj peev xwm (TLC) yog tag nrho cov ntim ntawm lub ntsws, thiab nws yog cov sum ntawm residual ntim thiab tseem ceeb muaj peev xwm. Qhov nruab nrab TLC hauv cov txiv neej yog 6.0 L, thiab cov poj niam, nws yog 4.2 L.
Qhov txawv ntawm lub ntsws Volume thiab lub ntsws muaj peev xwm yog dab tsi?
• Lub ntsws muaj peev xwm ua ke ntawm ob lossis ntau lub ntsws ntim.
• Tus nqi ntawm lub ntsws ntim tsawg dua li lub ntsws muaj peev xwm.
• Inspiratory Reserve Volume (IRV), Tidal Volume (VT), Expiratory Reserve Volume (ERV), thiab Residual Volume (RV) yog hom ntsws ntim, qhov Inspiratory Capacity (IC), Functional Residual Capacity (FRC), Vital Capacity (VC), thiab Total Lung Capacity (TLC) yog hom mob ntsws.
• Thaum txiav txim siab txog lub ntsws ntim, qhov seem seem tsis tuaj yeem ntsuas ncaj qha los ntawm qhov yooj yim spirometry thiab, hais txog lub ntsws muaj peev xwm, Lub Peev Xwm Muaj Peev Xwm yuav tsum ntsuas los ntawm kev siv txoj kev tsis ncaj.
