I-Endotracheal tube PVC compounds, eyaziwa nangokuthi i-polyvinyl chloride compounds, ibhekisela ezintweni ezithile ezisetshenziswa ekukhiqizeni amashubhu e-endotracheal.Amashubhu e-Endotracheal imishini yezokwelapha esetshenziselwa ukusungula nokugcina indlela yokuphefumula evulekile ngesikhathi sokuhlinzwa noma ezigulini ezigula kakhulu ezidinga umoya ohlanzekile.Izinhlanganisela ze-PVC ezisetshenziswa kumashubhu e-endotracheal akhiwe ngokucophelela ukuze ahlangabezane nezidingo zalolu hlelo lokusebenza lwezokwelapha olubucayi.Lezi zinhlanganisela zenzelwe ukuthi zihambisane ne-biocompatible futhi zingabi nobuthi, ziqinisekise ukuthi azibangeli noma yikuphi ukusabela okubi noma zilimaze indlela yokuphefumula yesiguli noma isimiso sokuphefumula.Izingxube ze-PVC ezisetshenziswa kumashubhu e-endotracheal kumele futhi zibe nezakhiwo ezithile zomzimba ukuze zisebenze ngempumelelo.Kufanele ziguquguquke kodwa zibe namandla ngokwanele ukugcina ukuma kweshubhu ngesikhathi sokufakwa nokusetshenziswa.Lezi zinhlanganisela kufanele futhi zimelane ne-kinking noma ukuwa, ukuqinisekisa ukugeleza komoya okufanele emaphashini esiguli.Ukwengeza, ama-PVC compounds asetshenziselwa amashubhu e-endotracheal angase abe nezithasiselo zokuthuthukisa izakhiwo ezithile.Isibonelo, izithasiselo ze-radiopaque zingafakwa ukunika amandla ukubonakala ngaphansi kwesithombe se-X-ray, kube lula ukuqinisekiswa kokubekwa kweshubhu okulungile.Izithasiselo ezilwa namagciwane zingase futhi zisetshenziselwe ukunciphisa ingozi yokutheleleka okuhambisana nokusetshenziswa isikhathi eside kweshubhu.Nokho, kuhle ukusho ukuthi i-PVC njengento esetshenziswayo iye yabhekana nokukhathazeka okuthile mayelana nomthelela wayo ongase ube khona emvelweni nempilo yabantu.Ngenxa yalokho, abacwaningi nabakhiqizi bahlola ngenkuthalo ezinye izinto ezisetshenziswayo kanye nobuchwepheshe bamashubhu e-endotracheal anganikeza ukusebenza okufanayo noma okuthuthukisiwe ngenkathi bebhekana nalezi zinto ezikhathazayo.Ngokufingqa, i-endotracheal tube PVC compounds yizinto ezenziwe ngokukhethekile ezisetshenziselwa ukukhiqizwa kwamashubhu endotracheal.Lezi zinhlanganisela zenzelwe ukuba zibe yi-biocompatible, ziguquguquke, futhi ziqine, ziqinisekise ukuphathwa komzila womoya ophephile futhi ophumelelayo ngesikhathi sokuhlinzwa noma ukungeniswa komoya ngemishini ezigulini ezigula kakhulu.
