Mayeso Akuyesa Kutsika kwa Mipingo Yathu ndi Chifuwa
Mphamvu yotsalira yogwira ntchito (FRC) imatanthawuza kuchuluka kwa mpweya wotsala m'mapapu mutatha mpweya wabwino. Amagwiritsidwa ntchito pofufuza kutsika kwa mapapu ndi khoma la chifuwa kwa anthu omwe ali ndi matenda opuma monga matenda osokoneza bongo (COPD) .
Chifukwa Chachikulu Chokhazikika Chokha Ndi Chofunika
Pamene mutuluka, simungathamangitse mpweya wanu m'mapapu anu.
Zina zidzatsalira pambuyo pa kutuluka mpweya kuti zikhale zotetezeka.
Ganizilani izi ngati buluni zomwe zimakhala zosavuta kudzaza ngati atakhala theka. Mfundo yomweyi imagwiranso ntchito m'mapapo. Mpweya wotetezedwa (wotchedwa functional residual volume) umalola mapapu kukhala ochepa pokhapokha atakhala ndi mphamvu zozizira komanso kutuluka mozizira. Popanda malire, kusinthasintha pakati pa mpweya ndi carbon dioxide mu alveoli yathu kungakhale kosiyana, nthawi zina kwambiri.
Cholinga cha Ntchito Yogwirira Ntchito
FRC ikulingalira mfundo yomwe mphamvu zamkati zamapapu zimapikisana ndi chizolowezi cha khoma la chifuwa kuti apite panja.
Ngati inhalation ndi kutulutsa mpweya zili bwino, palibe mpikisano ndi kupuma kumaonedwa kuti ndibwino. Koma, ngati sali bwino, tikhoza kutenga ma molekyulu a oxygen m'magazi athu kapena kuchotsa mpweya woipa m'magazi athu.
FRC ndi mayeso amodzi omwe dokotala angagwiritse ntchito pofufuza COPD yanu. Zina zimaphatikizapo kuchuluka kwa mphamvu yosungirako mankhwala (FEV) , yomwe imayesa kuchuluka kwa mpweya mumphindi imodzi, ndi mphamvu yolimbikitsidwa (FVC), yomwe imayesa kuchuluka kwa mpweya womwe umathamangitsidwa m'mapapo.
FRC ikhoza kukhala yowonjezera bwino ya zomwe zikuchitika m'mapapu anu chifukwa mpweya wambiri umakhala m'malo mopumula mwamphamvu.
Kulumikizana pakati pa COPD ndi Kugwira Ntchito Yotsitsimula
COPD imadziwika ndi kutaya kwa mapapo. Izi zimachepetsa njira yomwe timapuma ndikuwongolera ku FRC (hyperinflation).
Hyperinflation, nayenso, imayambitsa vuto limene timaitcha dyspnea , kapena kupuma pang'ono. Izi zikachitika, muyenera kupuma mofulumira kuti mupeze mpweya wokwanira m'mapapu anu. Zimachepetsa luso lanu lochita masewera olimbitsa thupi kapena kuchita ntchito yolimbika chifukwa mulibe oxygen yokwanira yomwe imatulutsidwa kuti mutumikire maselo, mtima, ndi ubongo wanu.
FRC ingasinthe chifukwa cha zinthu zina zoposa COPD. Zingathe kuchepa pamene kulimbikitsana kosalekeza pa phokoso, monga momwe zingathere panthawi ya mimba, pamene chiwindi chanu kapena nthenda yakulirakulira, kapena ngati pali madzi okwanira m'mimba ( ascites ) yomwe imayambitsa khansa ya chiwindi kapena chiwindi. Mosiyana ndi zimenezi, zikhoza kuwonjezeka pamaso pa njira yowonongeka kwa mpweya yomwe ikuwonetsedwa kwa anthu omwe ali ndi emphysema .
Momwe FRC imalangizira COPD Chithandizo
COPD imapangitsa kuti thupi likhale lopweteketsa thupi lomwe limakhudza mphamvu zonse za minofu ndi kutsika kwa khoma la chifuwa. Zolakwitsa izi zimangowonjezera zizindikiro za COPD ndipo ndicho chifukwa chachikulu chomwe chikhalidwe cha thupi chimakhala chofunikira kwambiri kwa anthu omwe ali ndi matendawa.
Malingana ndi matenda anu komanso kuopsa kwa zizindikiro zanu, dokotala wanu angapereke njira yothandizira thupi pogwirizana ndi dongosolo lolimbitsa thupi lomwe limagwirizana ndi zolephera zanu. Pachifukwa ichi, FRC idzagwiritsidwa ntchito poyendetsa patsogolo.
Pazifukwa zovuta pamene kuchita masewero olimbitsa thupi sikutheka, kupuma kwapuma kotha nthawi (PEEP) (mawonekedwe osapatsirana a mpweya wabwino) angagwiritsidwe ntchito kuthandizira kupuma.
