Spirometry analysis ndechidzidzo chekushanda, umo nyanzvi dzinoona huwandu hwayo nekukurumidza. Kuongorora kwakadaro kwakakosha kuti kuongororwa kwezvirwere, imwe nzira kana imwe inobatanidza nekushaya simba kwekupumha basa, kana kukwana kushandiswa kwemhepo mukati memuviri.
Mhando dze spirometry
Mazuva ano pane 4 maitiro evirometric samples:
- maitiro ekushanda, anoshandisa mishonga inokosha - bronchodilators, kubvisa bronchospasm.
- muedzo wokudzikama kufema;
- kukamanikidzwa kupfurikidza test;
- maximum ventilation test.
Nokuti muenzaniso unoshandisa chigadzirwa chakakosha - spirometer, iyo inokubvumira kuti uone kuwanda kwemhepo inouya kumapapu. Inoshandiswa pakuongorora kwakakwana kwenyika yekufema, iyo inenge yakakodzera yekuzivikanwa uye kurapwa kweimwe zvirwere.
Contraindications uye zvinangwa zve spirometry yemapapu
Iyi nzira yekuongororwa haigone kusakwana pamiganhu yemakore uye haina zvinopesana.
Zvinotendwa kuti spirometry inofanira kuitwa nevose vanoputa, kamwechete kamwe pagore, kuitira kutarisa mamiriro emamiriro ekufema uye, kana zvichifanira, kuona kushungurudzwa kwenguva.
Spirometry inogona kuona zvirwere zvepapupa, utano hwemwoyo, uye kudzidza nzira yakakodzera yekufema .
Iyi nzira inokubvumira kuti uone kuora kwemhepo, chirwere chekuvhara maperembudzi, uye sarcoidosis.
Spirometry
Nokuti iyo nzira inoshandisa spirometer, iyo inonyatsorondedzera yakawanda yemhepo inhaled and exhaled. Kuti uchengetedze sterility yenzira yacho, chigadzirwa chacho chinopiwa munyaya imwe neimwe muromo unogadziriswa.
Chokutanga, murwere anokumbirwa kutora kufema kwakadzika uye kubata mweya wake, mushure mekunge iwe unofanirwa kupfugama zvakasimba kumuromo, uye wozofambisa zvakanaka uye nekunyora zvakanaka mweya. Mune zvirwere zvisingaperi zvepapupa, izvi zvinogona kutora masevhisi gumi nemashanu. Mushure mokunge mhepo inopera yakapera, murwere anobvunzwa kutora mweya wakafema, kubata mweya wake uye kubudisa mweya nekuedza.
Muchiitiko chekutanga, kufema kufema kunotaridzika, uye mune yechipiri - simba rekufema.
Nokururamisa kwedata, iyi nzira inoitwa katatu uye yakaenzana nhamba yakabuda.
Decoding spirometry
Spirometry ine zviratidzo zvakawanda:
- AKARARA - hunokosha hwemapapu;
- FVC - nekumanikidzirwa kumanikidzirwa, musiyano pakati pemhepo yepamusoro pamapapu pakutanga uye pakuguma kwekufema kunoverengwa;
- FEV1 - kupera simba mukati mekutanga yechipiri;
- PIC - kupisa kwemafuro;
- MOS - kukurumidza kwemhepo kufamba panguva yekupera.
Miitiro ye spirometry
Izvi zvinotevera zvinoratidzirwa muparamende yeLEL, iyo inowanikwa muzvikamu:
- chimiro - zvinopfuura 90%;
- zvinokonzerwa noruzhinji - 85-90%;
- Kusiyanisa kunononoka - 70-84%;
- kukanganisa kukuru - 50-69%;
- kukanganisa kwakapinza - pasi pe50%.
Kune FEV1 parameter, mitero inotevera inoratidzwa se peresenti:
- chimiro - kupfuura 85%;
- mamiriro ezvinhu ezvo - 75-85%;
- Kukanganisa kunononoka - 55-74%;
- kukanganisa kukuru - 35-54%;
- kukanganisa kwakapinza - kudarika 35%.
