Lisebelisoa tsa Valve ea APL
Ho hlahloba Botšepehi ba Mochini oa Anesthesia
Tšebeliso e 'ngoe ea bohlokoa ea valve ea APL ke ho netefatsa botšepehi ba mochine oa anesthesia.Mekhoa e fapaneng e ka sebelisoa, ho latela tataiso ea moetsi.Ka mohlala, ka mor'a ho hokahanya mochine oa anesthesia ho potoloho ea phefumoloho, motho a ka koala valve ea APL, a koala sehokelo sa Y sa potoloho ea phefumoloho, 'me a lokise phallo ea oksijene le valve ea ho phalla ka potlako ho finyella khatello ea moea ea 30 cmH2O.Haeba pointer e lula e tsitsitse bonyane metsotsoana ea 10, e bolela botšepehi bo botle ba mochine.Ka ho tšoanang, motho a ka leka mochine ka ho beha valve ea APL ho 70 cmH2O, ho koala phallo ea oksijene, le ho kenya letsoho ho phalla ka potlako.Haeba khatello e sala ho 70 cmH2O, e bontša mokhoa o tiisitsoeng hantle.

Nakong ea ho phefumoloha ha mokuli ka tšohanyetso, belofo ea APL e lokela ho fetoloa hore e be “0” kapa “Spont.”Litlhophiso tsena li bula valve ea APL ka botlalo, ho netefatsa hore khatello e ka har'a potoloho ea phefumoloho e lula e le haufi le zero.Tlhophiso ena e fokotsa bakuli ba eketsehileng ba khanyetso ba neng ba tla kopana le bona nakong ea ho hema ka tšohanyetso.
Ho kenngoa ha Moea o Laoloang
Bakeng sa moea o kenang ka letsoho, valve ea APL e lokisoa sebakeng se loketseng, hangata pakeng tsa 20-30 cmH2O.Sena se bohlokoa kaha khatello e phahameng ea moea hangata e lokela ho bolokoa ka tlase ho 35 cmH₂O.Ha u fana ka moea o motle oa khatello ka ho penya mokotla oa ho phefumoloha, haeba khatello nakong ea pululelo e feta boleng ba valve ea APL e behiloeng, valve ea APL ea bula, e lumellang khase e feteletseng ho baleha.Sena se tiisa hore khatello e laoloa, ho thibela kotsi ho mokuli.
