Kodi pulmonary surfactant ndi momwe imagwirira ntchito
Zamkati
Wogwiritsira ntchito m'mapapo ndi madzi opangidwa ndi thupi omwe ali ndi ntchito yothandizira kusinthana kwa mpweya wopuma m'mapapu. Zochita zake zimalola kuti pulmonary alveoli, omwe ndi timatumba tating'onoting'ono tomwe timasinthana ndi mpweya, akhale otseguka panthawi yopuma, kudzera pamavuto, omwe amathandizira kulowa kwa mpweya m'magazi.
Makanda obadwa kumene asanakwane sangakhale ndi makina okwanira ogwira ntchito m'mapapo kuti athe kupuma bwino, motero, amatha kudwala matenda opatsirana opatsirana, omwe amachititsa kupuma movutikira.
Mwamwayi, pali mankhwala, omwe ndi ochita masewera olimbitsa thupi, omwe amatsanzira zinthu zachilengedwe za thupi, ndipo amathandiza kupuma kwa mwana mpaka atadzipangira yekha. Mankhwalawa amatha kuperekedwa mu ola loyamba mwana akabadwa, chifukwa chofulumira, kudzera mu chubu m'mapapu.
Ntchito za surfactant
Ntchito yayikulu yama pulmonary surfactant ndikupanga kanema wosanjikiza yemwe amalola kutsegulidwa koyenera kwa pulvement alveoli ndikulola kupuma, kudzera:
- Kusamalira kutsegulidwa kwa alveoli;
- Kuchepetsa mphamvu yofunikira pakukulitsa mapapu;
- Kukhazikika kwa kukula kwa alveoli.
Mwanjira imeneyi, mapapo amakhala otakataka nthawi zonse ndipo amatha kuchita bwino kupatsirana mpweya.
Zomwe zimayambitsa kusowa kwa othamanga
Wogwira ntchitoyo amapangidwa nthawi yakukhwima kwamapapu amwana, akadali m'mimba mwa mayi, patatha milungu pafupifupi 28. Chifukwa chake, ana obadwa masiku asanakwane omwe amabadwa nthawi imeneyi isanakwane, sangakhale ndi zinthu zokwanira zopangira mankhwalawa, zomwe zimayambitsa vuto la kupuma kwamwana.
Matendawa, omwe amadziwikanso kuti hyaline membrane syndrome kapena kupuma kwamavuto, amapangitsa kupuma movutikira, kupuma mwachangu, kupumira komanso milomo yabuluu ndi zala, zomwe zitha kupha.
Pakadali pano, dokotala wa ana amatha kuwonetsa mwana wakhanda kuchuluka kwa mankhwala osokoneza bongo, omwe atha kukhala achilengedwe, otengedwa munyama, kapena opanga, omwe angalowe m'malo mwa wogwira ntchito m'mapapu ndikupangitsa kupuma mokwanira. Phunzirani zambiri za zizindikilo komanso momwe mungachiritse matenda opatsirana aubwana.
