Munyika yemichina yeanesthesia, kune chikamu chakazvininipisa asi chakakosha chinozivikanwa se APL (Adjustable Pressure Limiting) valve.Ichi chishandiso chisingatarisirwi, chinowanzo shandiswa nevanotindivadza panguva yekurapwa, chinoita basa rakakosha mukuona kuchengetedzwa uye kushanda kwemhepo yemurwere.
Kushanda Nheyo yeAPL Valve
Iyo APL valve inoshanda pane iri nyore asi yakakosha musimboti.Inosanganisira chitubu-yakatakura dhisiki, uye basa rayo rinosanganisira kugadzirisa kudzvanywa mukati memhepo yekufema.Nekutenderedza knob, kushushikana kwechitubu uye nokudaro kumanikidza kunoshandiswa kune diski kunogona kuchinjwa.Ivhavha inoramba yakavharwa kusvikira kudzvinyirirwa mumhepo yekufema, inomiririrwa nemuseve wakasvibirira, inopfuura simba rinoshandiswa nechitubu, chinoratidzwa nemuseve wepinki.Ipapo ndipo panovhurwa vharuvhu, ichibvumira gasi rakawandisa kana kumanikidza kutiza.Iyo gasi inoburitswa neiyo APL valve inowanzotungamirwa kune yekutsvaira system, kuve nechokwadi kubviswa kwakachengeteka kwemagasi akawandisa kubva mukamuri yekushandisa.
Zvikumbiro zveAPL Valve
Kutarisa Anesthesia Machine Kutendeseka
Kumwe kwakakosha kushandiswa kwevharuvhu yeAPL kuri mukuona kuvimbika kwemuchina weanesthesia.Nzira dzakasiyana-siyana, zvichienderana nemirairo yemugadziri, inogona kushandiswa.Semuenzaniso, mushure mekubatanidza muchina weanesthesia kudunhu rekufema, munhu anogona kuvhara APL valve, occlude Y-connector yemhepo yekufema, uye kugadzirisa kuyerera kweokisijeni uye kukurumidza kuyerera kwevhavha kuti iwane mhepo yekumanikidza kuverenga kwe30 cmH2O.Kana iyo pointer ikaramba yakagadzikana kweinenge gumi masekonzi, inoratidza yakanaka yemuchina kutendeseka.Saizvozvo, munhu anogona kuyedza muchina nekuisa iyo APL valve pa 70 cmH2O, kuvhara kuyerera kweokisijeni, nekuita iyo inokurumidza kuputika.Kana dzvinyiriro ikaramba iri pa70 cmH2O, inoratidza hurongwa hwakavharwa.
Murwere-Spontaneous Breathing State
Panguva yekufema kwemurwere zvega, vharuvhu yeAPL inofanirwa kugadziriswa kuita “0” kana “Spont.”Aya marongero anovhura zvizere APL valve, kuve nechokwadi kuti kudzvanywa mukati memhepo yekufema kunoramba kuri pedyo ne zero.Kugadziriswa uku kunoderedza kuwedzera kwevarwere vangazosangana nazvo panguva yekufema kwega.
Induction of Controlled Ventilation
Nekufemesa kwemaoko, iyo APL valve inogadziriswa kune yakakodzera kugadzika, kazhinji pakati pe20-30 cmH2O.Izvi zvakakosha sezvo peak airway pressure inofanirwa kuchengetwa iri pasi pe35 cmH₂O.Paunenge uchipa kudzvanywa kwemhepo nekudzvanya bhegi rekufema, kana kumanikidza panguva yekufemerwa kunopfuura iyo yakatarwa APL valve kukosha, iyo APL valve inovhura, ichibvumira yakawandisa gasi kutiza.Izvi zvinovimbisa kuti kudzvinyirira kunodzorwa, kudzivirira kukuvadza kumurwere.
Kugadziriswa kweMechanical Ventilation panguva yekuvhiya
Munguva yekufefetedza kwemechani, iyo APL vharafu inonyanya kunzvenga, uye kuiswa kwayo hakuna zvakunoita.Nekudaro, sekuchenjerera, itsika kugadzirisa iyo APL vharafu kuita “0” panguva yemuchina wekudzora mhepo.Izvi zvinofambisa kushanduka kwekutonga kwemaoko pakupera kwekuvhiyiwa uye inobvumira kutarisa kwekufema kwega.
Kuwedzerwa kwemapapu pasi peAnesthesia
Kana inflation yemapapu ichidiwa panguva yekuvhiyiwa, valve yeAPL inogadzirirwa kune imwe nzvimbo inokosha, kazhinji pakati pe20-30 cmH₂O, zvichienderana nepamusoro-soro inodiwa yekufuridzira.Ukoshi uhwu hunoita kuti inflation idzorwe uye inodzivirira kudzvinyirira kwakanyanya pamapapu emurwere.
Mukupedzisa, nepo APL vharafu ingaita seisingaoneki munyika yeaneshesia michina, basa rayo rakakosha zvisingarambiki.Inobatsira kuchengetedzwa kwemurwere, kufefetedza kunoshanda, uye kubudirira kwese kwemaitiro ekurapa.Kunzwisisa nuances yeAPL valve uye maitiro ayo akasiyana-siyana zvakakosha kune anesthetist uye vashandi vehutano hwehutano kuti vave nechokwadi chekugara kwevarwere vari kutarisira.
