Kuyini i-VQ Scan? Ake sixoxe ngakho kalula!

Njengoba wazi, odokotela basebenzisa izivivinyo ezahlukahlukene ukuthola izinkinga emizimbeni yethu. Cishe ujwayelene nezinto ezifana ne-X-ray kanye ne-CT scans. Namuhla sizokhuluma ngohlobo oluhlukile kancane lwe-scan olusetshenziswa futhi ukubheka ngokujulile ukusebenza kwamaphaphu ethu. Lokhu kubizwa ngokuthi i-VQ scan. Nakuba igama lingase lizwakale liyinkimbinkimbi kancane, empeleni lilula impela.

Kalula nje, kuyini ukuskena kwe-VQ?

I-VQ scan iyisivivinyo esinezingxenye ezimbili, esingangenisi umswakama esithatha izithombe zamaphaphu akho futhi silinganise ukuhamba komoya kanye nokugeleza kwegazi kuwo.

Igama elithi 'V' egameni limelela i-Ventilation , okuyiyona ndlela umoya ohamba ngayo ungena futhi uphume emaphashini akho. Igama elithi 'Q' limelela i-Perfusion , okuyinani legazi eligeleza liye emithanjeni yegazi emincane emaphashini akho. Ngakho-ke ngezinye izikhathi libizwa ngokuthi i-Ventilation-Perfusion scan, i-lung scan, noma i-lung scintigraphy.

Kukuziphi izimo lapho lokhu kuskena kusetshenziswa khona?

Odokotela bavame ukusebenzisa i-VQ scan ukuhlola ukuthi igazi ligobile yini emaphashini akho (i-Pulmonary Embolism, noma i-PE) . Lokhu kungaba yingozi empilweni uma kungelashwa kahle. Kuphinde kusetshenziswe ukuxilonga i-CTEPH (Chronic Thromboembolic Pulmonary Hypertension) , isimo esibangela umfutho wegazi ophezulu emithanjeni yegazi yamaphaphu.

Akukhona lokho kuphela, kodwa lokhu kuskena kusiza nokuhlola ukusebenza kwamaphaphu akho ngezinye izindlela eziningana.

• Ngemva kokufakelwa amaphaphu.
• Ngaphambi kokuhlinzwa ukuze kususwe iphaphu noma ingxenye yalo.
• Lapho kutholakala noma kwelashwa ezinye izimo zamaphaphu, njenge -COPD (Isifo Esingapheli Sokuvimbela Amaphaphu) .

Uyini umehluko phakathi kwe-VQ scan kanye ne-CT scan?

Nakuba zombili izinhlobo zokuskena zithatha izithombe zamaphaphu futhi zisiza ekutholeni izinkinga ezifana nokuqhekeka kwegazi, kunomehluko ocacile phakathi kwalokhu okubili. Ake sizibheke etafuleni.

Kufanele ngilungiselele kanjani ngaphambi kokuskena?

Empeleni, lokhu kuskena akudingi ukulungiswa okukhethekile. Ungadla ngendlela evamile futhi uphuze imithi yakho. Kodwa-ke, kufanele utshele udokotela wakho ngalokhu okulandelayo:

• Uma ukhulelwe noma usola ukuthi ukhulelwe: Lokhu kuskena kuhilela inani elincane lemisebe, ngakho akuphephile enganeni engakazalwa. Ezimweni ezinjalo, udokotela wakho angase ancome okunye ukuhlolwa.
• Uma ungumama oncelisayo: Njengoba into esetshenziswayo ekuhlolweni ingadlulela obisini lwebele, udokotela wakho uzokunikeza imiyalelo ekhethekile mayelana nendlela yokuncelisa ingane yakho usuku olulodwa noma ezimbili ngemva kokuskena.
• Uma unenkinga yokuhlala ungashintshi endaweni eyodwa imizuzu eminingana: Uma unyakaza ngesikhathi sokuskena, izithombe ngeke zicace. Ngakho-ke kubalulekile ukusazisa ngalokhu kusenesikhathi.

I-X-ray yesifuba ivame uku-odwa zingakapheli amahora angama-24 kusukela ku-VQ scan. Ulwazi olutholakala kulokhu luzosiza udokotela ukuqonda imiphumela ye-VQ scan.

Kwenzekani ngesikhathi sokuskena?

Lokhu kuhlolwa kuthatha imizuzu ephakathi kuka-30 no-60 ukuphothulwa. Kunezingxenye ezimbili. Abanye abantu banengxenye eyodwa kuphela eyenziwe, kodwa iningi labantu liqede zombili izingxenye ngosuku olufanayo.

Ingxenye Yokuqala: Ukuskena Komoya

Lokhu kuhilela ukubheka ukuthi umoya ungena kanjani emaphashini akho.

1. Okokuqala, uzofakelwa i-mouthpiece noma i-mask emboza umlomo nekhala lakho. Kungadingeka futhi ufake i-clip encane ekhaleni lakho ukuqinisekisa ukuthi uphefumula ngomlomo wakho kuphela.

2. Bese kuthi, ngepayipi elixhunywe kule divayisi, kufakwe inani elincane kakhulu lento enemisebe (i-tracer) emoyeni owuphefumulayo. Cabanga ngakho njengokufaka ithegi encane enemibala emoyeni owuphefumulayo.

3. Uzolaliswa embhedeni okhethekile bese uthunyelwa emshinini ofana nesilinda. Noma uzohlaliswa esihlalweni bese ubekwa phambi kwekhamera.

4. Njengoba uphefumula ngale mask, ikhamera ekhethekile izothatha izithombe zamaphaphu akho. Ungase uguqulwe ube yizindawo ezahlukene ukuze uthathe izithombe ezidingekayo.

Ingxenye Yesibili: Ukuskena Kwe-Perfusion

Lesi sigaba siqedwa ngokushesha nje lapho ukuhlolwa komoya sekuqediwe. Lesi sigaba sibheka indlela igazi eligeleza ngayo emaphashini.

• Kulokhu, into ekhipha imisebe (i-tracer) ayiphefumulwa. Kunalokho, ifakwa emthanjeni ongalweni yakho nge -IV .
• Bese, besebenzisa ikhamera efanayo naleyo yangaphambilini, bathatha izithombe zegazi eligeleza emaphashini akho.

Ngiyithola kanjani imiphumela ngemva kokuskena?

Ungabuyela emisebenzini yakho evamile ngemva kokuskena. Izinto ezikhipha imisebe emzimbeni wakho zizophuma emzimbeni wakho ngokwemvelo ngokuphefumula kwakho, umchamo, kanye nendle zingakapheli amahora ambalwa noma izinsuku ezimbalwa. Ngokuvamile uzothola imiphumela yakho zingakapheli amahora angu-24.

Uma umbiko wemiphumela uthi "Okuvamile" noma "Amathuba aphansi," lokho kusho ukuthi akukho ukugoba kwegazi. Uma uthi okuthile okufana nokuthi "Amathuba aphakathi," lokho kusho ukuthi akucaci, futhi kungase kudingeke ukuhlolwa okwengeziwe. Uma uthi "Amathuba aphezulu," lokho kusho ukuthi kunethuba elikhulu lokugoba kwegazi, futhi udokotela wakho uzokhuluma nawe ngokwelashwa okudingayo.

Kunini lapho udinga ukubonana nodokotela ngokushesha?

Uma uba nezimpawu zokuqhekeka kwegazi emaphashini akho (pulmonary embolism) , kuyisimo esiphuthumayo.Shayela udokotela wakho ngokushesha, noma uye egumbini lezimo eziphuthumayo esibhedlela esiseduze (i-ETU). Qaphela lezi zimpawu:

• Ubunzima bokuphefumula ngokuzumayo.
• Ubuhlungu obukhulu esifubeni, engalweni, ehlombe, entanyeni, noma emhlathini.
• Ukukhwehlela ngegazi noma ngaphandle kwalo.
• Isikhumba esimpunga kanye nomjuluko onamathelayo.
• Ukushintsha kombala wesikhumba, izindebe, noma izinzipho (i-cyanosis).
• Isilinganiso senhliziyo siyanda.
• Ukujuluka ngokweqile.
