Lung kupararira kuyedzwa

Lung diffusion kuyedza kuyera kuti mapapu anochinjisa sei magasi. Ichi chikamu chakakosha pakuongororwa kwemapapu, nekuti basa hombe remapapu kubvumira kuti oksijeni "ipararire" kana kuti ipinde muropa kubva mumapapu, uye kubvumira kabhoni dhayokisaidhi "kupararira" kubva muropa kuenda mumapapu.

Unofemera mukati (inhale) mweya une shoma shoma kwazvo kabhoni monoxide uye gasi rinoteedzera, senge methane kana helium. Iwe unobata mweya wako kwemasekondi gumi, wobva wakurumidza kurifuridzira kunze (exhale). Iyo gasi rakaburitswa rinoyedzwa kuti rione kuti yakawanda sei tracer gasi yakatorwa panguva yekufema.

Usati watora bvunzo iyi:

• Usadye chikafu chinorema usati waedzwa.
• Usapute kweanenge maawa mana kusvika matanhatu usati waedzwa.
• Kana iwe ukashandisa bronchodilator kana imwe mishonga inhaled, bvunza wako mupi wezvehutano kana iwe uchigona kushandisa iyo usati waedzwa.

Iyo yekutaurisa inokodzera zvakasimba pamuromo wako. Mapikicha anoiswa pamhino dzako.

Muedzo unoshandiswa kuongorora zvimwe zvirwere zvemapapu, uye kuongorora chinzvimbo chevanhu vane chirwere chemapapu chakasimbiswa. Kudzokorora kudzokorora kugona kunogona kubatsira kuona kana chirwere ichi chiri kuwedzera kana kutowedzera.

Zvakajairwa bvunzo mhedzisiro zvinoenderana newemunhu:

• Zera
• Zvepabonde
• Kureba
• Hemoglobin (iyo puroteni mumasero matsvuku eropa anotakura oxygen)

Mhedzisiro isina kujairika inoreva kuti magasi haafambi zvakajairika pamusoro pemapapu emapapu kuenda mumidziyo yeropa yemapapu. Izvi zvinogona kukonzerwa nezvirwere zvemapapu senge:

• COPD
• Mukati me fibrosis
• Pulmonary embolism
• Pulmonary hypertension
• Sarcoidosis
• Kubuda ropa mupapu
• Asima

Iko hakuna akakosha njodzi.

Mamwe mapurmonary function test anogona kuitwa pamwe nemuedzo uyu.
