Parizvino, maventilator epamba uye majenareta eokisijeni anonyanya kufarirwa midziyo yekurapa yemumba.Vanhu vazhinji vanovhiringika pamusiyano uripo pakati peventilator neokisijeni jenareta.Vanotora mhepo inofefetera sejenareta weokisijeni uye vanofunga zvisiri izvo kuti mhepo inofefetera inogonawo kuburitsa oxygen.Muchokwadi, zvikasadaro, mhepo inofefetera uye okisijeni jenareta marudzi maviri emidziyo yekurapa ayo akasiyana zvakanyanya.Saka, ndeupi musiyano uripo pakati pemhepo inofefetera pamba nejenareta reokisijeni?
Musiyano uripo pakati pemhepo inofefetera uye okisijeni jenareta ndeyekuti vanoshandisa misimboti yakasiyana.
Nheyo yemhepo inofefetera pamba: Kufemba kwemhepo kunoburitsa yakashata thoracic pressure panguva yekuzvidira mhepo, uye passive mapapu kuwedzera kunokonzera alveolar uye airway yakaipa pressure, iyo inoumba mutsauko wepakati pakati pekuvhura kwemhepo uye alveoli kupedzisa inhalation;mushure mekufema, chifuva nemapapu The elastic retracts, ichigadzira zvakasiyana-siyana zvekumanikidza kupedzisa kufema.Naizvozvo, kufema kwakajairika kunokonzerwa nekufemerwa kwemapapu uye muromo wemhepo kuburikidza nekushanda kwakashata kudzvinyirira musiyano wemuviri kupedzisa inhalation, mushure mekufema kwe thoracic nemapapu elastic retraction inoburitsa alveolar uye airway muromo passive positive pressure musiyano uye exhale. kusangana nezvinodiwa zvefiziological ventilation.
Sepray isiri-invasive ventilator
Nheyo yeokisijeni jenareta: kushandiswa kwema molecular sieve yemuviri adsorption uye desorption tekinoroji.Iyo molecular sieve yakazadzwa mujenareta yeokisijeni, iyo inogona kushambadzira nitrogen mumhepo kana yakamanikidzwa, uye iyo yakasara isina kubatwa okisijeni inounganidzwa.Mushure mekucheneswa, inova yakakwira-kuchena okisijeni, iyo kazhinji isingakodzeri varwere vanorwara zvakanyanya!
Nekunzwisisa misimboti yemhepo inofefetera uye okisijeni jenareta, zviri nyore kusiyanisa pakati pemhepo inofefetera uye okisijeni jenareta.Zvichitaurwa zviri nyore, iyo pfungwa yeventilator yakasiyana neyeiyo jenareta weokisijeni.Iyo yekufemesa yakaita semhepo compressor, inopa kuyerera kwemhepo senge feni yemagetsi, iyo inoshandiswa kubatsira uye kutsiva kufema kwevanhu.Jenareta weokisijeni yakafanana nesefa, inoongorora kunze kweokisijeni iri mumhepo.Kune zvakare mhando mbiri dzemichina inoshandiswa muchipatara kurapa, kazhinji, hosha dzakakomba senge chirwere chemapapu uye kutadza kwemoyo.
Vanonyanya kushandisa maventilator emumba ndeaya: vanhu vakafuta, kukura kwemhino zvisina kujairika, pharyngeal hypertrophy uye gobvu, uvula obstruction channels, tonsil hypertrophy, abnormal thyroid function, giant tongue, congenital minor jaw deformity uye vamwe varwere Shandisa zviratidzo zvakadai sekuridza ngonono uye kufema kurara.
