Machubu a Endotracheal ndi zipangizo zachipatala zomwe zimagwiritsidwa ntchito pokhazikitsa ndi kusunga njira yotseguka panthawi ya opaleshoni kapena odwala omwe akudwala kwambiri omwe amafunikira mpweya wabwino. Mankhwalawa amapangidwa kuti azikhala ogwirizana komanso osakhala ndi poizoni, kuonetsetsa kuti samayambitsa vuto lililonse kapena kuvulaza mpweya wa wodwalayo kapena kupuma.Mapangidwe a PVC omwe amagwiritsidwa ntchito m'machubu a endotracheal ayeneranso kukhala ndi makhalidwe enieni a thupi kuti agwire bwino ntchito. Ayenera kukhala osinthika koma olimba mokwanira kuti asunge mawonekedwe a chubu pakuyika ndikugwiritsa ntchito. Mankhwalawa ayeneranso kukhala osagwirizana ndi kinking kapena kugwa, kuonetsetsa kuti mpweya ukuyenda bwino kumapapu a wodwalayo.Kuonjezera apo, mankhwala a PVC omwe amagwiritsidwa ntchito m'machubu a endotracheal akhoza kukhala ndi zowonjezera zowonjezera katundu. Mwachitsanzo, zowonjezera za radiopaque zitha kuphatikizidwa kuti zitheke kuwoneka pansi pa kujambula kwa X-ray, kuwongolera kutsimikizika koyenera kwa machubu. Zowonjezera zowononga tizilombo zingagwiritsidwenso ntchito kuchepetsa chiopsezo cha matenda okhudzana ndi kugwiritsa ntchito chubu kwa nthawi yaitali.Komabe, ndi bwino kutchula kuti PVC monga zinthu zakhala zikukumana ndi zovuta zina zokhudzana ndi momwe zingakhudzire chilengedwe ndi thanzi laumunthu. Chotsatira chake, ofufuza ndi opanga akufufuza mwakhama zipangizo zina ndi matekinoloje a machubu a endotracheal omwe angapereke ntchito yofanana kapena yowonjezereka pamene akulimbana ndi zovutazi.Mwachidule, endotracheal chubu PVC mankhwala ndi zipangizo zopangidwa mwapadera zomwe zimagwiritsidwa ntchito popanga ma endotracheal tubes. Mankhwalawa amapangidwa kuti azikhala ogwirizana, osinthasintha, komanso amphamvu, kuonetsetsa kuti njira yoyendera mpweya yotetezeka komanso yothandiza panthawi ya opaleshoni kapena mpweya wabwino kwa odwala omwe akudwala kwambiri.
