Chifukwa chiyani ma ventilator ndi ma jenereta okosijeni amafunikira kuti agwirizane ndi magawo a oxygen m'magazi?

Chifukwa chiyani ma ventilator ndi ma jenereta okosijeni amafunikira kuti agwirizane ndi magawo a oxygen m'magazi?

Mpweya wolowera mpweya ndi chipangizo chomwe chingalowe m'malo kapena kuwongolera kupuma kwamunthu, kuonjezera mpweya wa m'mapapo, kukonza kupuma bwino, komanso kuchepetsa kugwiritsa ntchito kupuma. Nthawi zambiri amagwiritsidwa ntchito kwa odwala omwe ali ndi vuto la pulmonary kapena kutsekeka kwa mpweya omwe sangathe kupuma bwino. Kupuma ndi kupuma kwa thupi la munthu kumathandiza wodwalayo kuti amalize kupuma kwa mpweya ndi kupuma.

Jenereta ya okosijeni ndi makina otetezeka komanso osavuta otulutsa mpweya wabwino kwambiri. Ndi jenereta yoyera ya okosijeni, imakanikiza ndi kuyeretsa mpweya kuti utulutse mpweya, ndiyeno amauyeretsa ndikuupereka kwa wodwalayo. Ndi oyenera kupuma dongosolo matenda, mtima ndi ubongo matenda. Kwa odwala matenda a mtima ndi okwera hypoxia, makamaka kuthetsa zizindikiro za hypoxia.

Ndizodziwika bwino kuti ambiri mwa odwala omwe amwalira ndi chibayo cha Covid-19 amakhala ndi kulephera kwa ziwalo zingapo chifukwa cha sepsis, ndipo kuwonetsa kulephera kwa ziwalo zingapo m'mapapo ndi pachimake kupuma kwapang'onopang'ono matenda a ARDS, kuchuluka kwazomwe zikuchitika pafupifupi 100% . Chifukwa chake, chithandizo cha ARDS chitha kunenedwa kuti ndichothandiza kwambiri kwa odwala omwe ali ndi chibayo cha Covid-19. Ngati ARDS sinasamalidwe bwino, wodwalayo akhoza kufa posachedwa. Panthawi ya chithandizo cha ARDS, ngati mpweya wa okosijeni wa wodwalayo udakali wochepa ndi cannula ya m'mphuno, dokotala amagwiritsa ntchito mpweya wothandiza wodwalayo kupuma, womwe umatchedwa mechanical ventilation. Mpweya wamakina umagawikanso m'makina opumira movutikira komanso osasokoneza mpweya wothandiza. Kusiyana pakati pa ziwirizi ndi intubation.

M'malo mwake, chibayo cha Covid-19 chisanachitike, "mankhwala okosijeni" anali kale chithandizo chofunikira kwa odwala omwe ali ndi matenda opuma komanso amtima. Thandizo la okosijeni limatanthawuza chithandizo cha kutulutsa mpweya kuti muwonjezere kuchuluka kwa okosijeni m'magazi ndipo ndi yoyenera kwa odwala onse omwe ali ndi hypoxic. Pakati pawo, matenda a dongosolo kupuma ndi dongosolo mtima ndi matenda aakulu, makamaka pa matenda aakulu obstructive m`mapapo mwanga matenda (COPD), okosijeni mankhwala wakhala akugwiritsidwa ntchito ngati yofunika adjuvant mankhwala m`banja ndi malo ena.

Kaya ndi chithandizo cha ARDS kapena chithandizo cha COPD, ma ventilator ndi ma concentrators okosijeni amafunikira. Kuti mudziwe ngati kuli kofunikira kugwiritsa ntchito mpweya wabwino wakunja kuti muthandizire kupuma kwa wodwalayo, ndikofunikira kuyang'anira kuchuluka kwa okosijeni m'magazi a wodwalayo panthawi yonse ya chithandizo kuti mudziwe zotsatira za "oxygen therapy".

Ngakhale kupuma kwa okosijeni kumapindulitsa thupi, kuvulaza kwa kawopsedwe ka okosijeni sikunganyalanyazidwe. Kawopsedwe wa okosijeni amatanthauza matenda omwe amawonetseredwa ndi kusintha kwa ma pathological mu magwiridwe antchito ndi kapangidwe kazinthu zina kapena ziwalo zina thupi litakoka mpweya pamwamba pa kukakamiza kwina kwa nthawi inayake. Choncho, nthawi yopuma mpweya wa okosijeni ndi mpweya wa okosijeni wa wodwalayo ukhoza kuwongoleredwa poyang'anira kuchuluka kwa okosijeni m'magazi mu nthawi yeniyeni.
