Kukosha kwe "kufema" uye "okisijeni"
1. Simba rinobuda: "injini" inotyaira muviri
Iri ndiro basa guru reokisijeni. Miviri yedu inoda simba kuti iite mabasa ese, kubva pakurova kwemoyo, kufunga kusvika pakufamba nekumhanya.
2. Kuchengetedza mabasa ekutanga emuviri: chinangwa chikuru chekurarama
Muviri une mabasa akawanda akakosha anoitwa nguva dzese uye anoenderana zvachose nekuwanikwa kwesimba nguva dzose, izvo zvisingagone kuitwa pasina okisijeni.
- Basa rehuropi: Uropi ndihwo hukuru hwemuviri. Kunyangwe huchingori 2% chete yehuremu hwemuviri, hunodya 20%-25% yeoxygen yemuviri. Mushure memaminitsi mashoma ekushaikwa kweoxygen, masero europi anotanga kukuvara, zvichikonzera dzungu, kuvhiringidzika, uye kunyange kukuvara zvachose.
- Kurova kwemoyo: Mwoyo itsandanyama inoshanda nguva dzose, ichipomba ropa rine oxygen mumuviri wese. Tsandanyama yemoyo pachayo inoda oxygen yakawanda kuti irambe ichisunga. Kushaikwa kwe oxygen kunogona kukonzera matambudziko emwoyo, angina, uye kunyange myocardial infarction (chirwere chemwoyo).
- Kugadzira muviri: Maitiro ese emakemikari mumuviri anotsigira hupenyu, akadai sekugaya chikafu, kugadzirisa matishu, uye kubvisa tsvina, anoda simba kuti afambe uye nekudaro anovimba neokisijeni zvisina kunanga.
3. Kuchengetedza kugadzikana kwemukati memuviri: "nyanzvi yekuenzanisa" yemuviri
Okisijeni inokosha pakuchengetedza nharaunda yemakemikari yakagadzikana mumuviri.
- Kuenzana kweasidhi-base: Kugayiwa kwemasero kunogadzira zvinhu zvine acidic (senge carbonic acid). Okisijeni inobatsira kuchengetedza pH yeropa nemvura yemuviri mukati mechikamu chakamanikana, chakagadzikana, izvo zvinodiwa kuti ma enzymes nemasero ashande zvakanaka.
- Kudzivirira immune system: Sisitimu yemuviri yemunhu, kunyanya mamwe masero emuviri (akadai semacrophages), inogadzira huwandu hwakawanda hwe "reactive oxygen species" dzinoita kuti muviri uve neoksijeni yakawanda sezvombo painomedza nekuparadza mabhakitiriya, mavhairasi, nezvimwe zvirwere. Kushanda zvakanaka kwemaitiro aya kwakabatana zvakanyanya nehuwandu hweokisijeni.
Kune avo vanoda rubatsiro rwekuwedzera rweokisijeni, matangi eokisijeni echinyakare akakura, anoda kutsiviwa, uye ane njodzi dzekuchengetedza. Saka, pane mhinduro iri nyore uye inogara kwenguva refu here?
Ehe, ichocho chinhu chinochengetedza okisijeni - chishandiso chakangwara chinoburitsa okisijeni mumhepo yakatipoteredza. "Funga nezvechinhu chinochengetedza okisijeni sesefa yemhepo yakangwara kwazvo. Chinotora mhepo yenguva dzose, chinosefa magasi asingadiwe, uye chinokusiya uine okisijeni yepamusoro yekurapa kuti ufeme."
"Nhengo" yemuchina we oxygen concentrator
1. Sefa yemhepo: "Nzira yekutanga yekudzivirira," ine basa rekubvisa guruva, zvinhu zvinokonzera allergy nezvimwe zvinhu kubva mumhepo.
2.Compressor: "Moyo wemuchina", une basa rekumanikidza mweya unofemerwa.
3. Sefa yemamorekuru: "Chikamu chemashiripiti," chakazadzwa nezvidimbu zvakakosha zvinonzi zeolites zvinonwisa nitrogen zvakanaka kwazvo.
4. Tangi rekuchengetera gasi/tangi rebuffer: rinoshandiswa kuchengetedza okisijeni yakacheneswa kuti mhepo ibude zvakanaka.
5. Chiyero chemuchina wekuyerera kwemhepo nekanzuru yeoxygen yemhino: Chishandiso chekutonga kwemushandisi chinoshandiswa kugadzirisa kuyerera kweoxygen kunodiwa uye kuendesa oksijeni kumushandisi.
Mashiripiti ekuti "mhepo inoshanduka kuita okisijeni"
1. Kufema uye kusefa
Muchina uyu unodhonza mhepo iri mukamuri (inenge 78% nitrogen, 21% oxygen). Sekunge tinofema zvakadzika.
2.Kudzvanya
Compressor inodzvanya mweya unosvutwa, Gadzirira nzira inotevera yekuparadzanisa.
3. Kuparadzana
Mhepo yakamanikidzwa inoiswa muchikamu chesefa chemolecular, Zvidimbu zve zeolite zvinoshanda se "nitrogen magnet" ine simba, ichikwezva mamorekuru enitrogen mumhepo uku ichibvumira mamorekuru madiki eoxygen kuti apfuure nepakati. Chinobuda kubva kune rimwe divi resefa yemolecular ioxygen ine huwandu hunosvika 90%-95%.
4.Kubuda uye loop
(Okisijeni inobuda): Okisijeni yakachena kwazvo inoiswa mutangi regesi yozoendeswa kumushandisi kuburikidza nemuchina wekuyeresa flow meter uye nasal oxygen cannula.
(Chinoburitsa Nitrogen): Panguva imwe chete, imwe shongwe yekusefa yemamorekuru inodzosera nitrogen yakanyungudutswa (iyo isingakuvadzi) mumhepo nekuderedza kumanikidzwa. Mashongwe maviri aya anotenderera kuburikidza netekinoroji ye pressure swing adsorption, zvichiita kuti okisijeni irambe ichibuda.
Zvakafanana nevashandi vaviri vari kuita majana vachishanda, mumwe achisefa mhepo ukuwo mumwe achichenesa "marara" (nitrogen), nokudaro vachiwana okisijeni yakakwana maawa makumi maviri nemana pazuva, mazuva manomwe pasvondo.
Kuyerera kwePulse vs. Kuyerera Kunoramba Kuchienderera
1.Kuyerera Kunoramba Kuchienderera: Inoramba ichipa okisijeni serukova rusingaperi. Yakanakira vanhu vakarara kana vashandisi vanoda okisijeni nguva dzose.
2.Kuyerera kwePulse: Nzira yekuchenjera. Kuputika kweokisijeni kunounzwa chete kana mushandisi afema. Izvi zvinoshandisa simba shoma uye zvinowedzera hupenyu hwebhatiri remuchina unotakurika weokisijeni.
Mazano akakosha ekuchengetedza
1. Zvigadziriso zveokisijeni zvinopa okisijeni yakawandisa, kwete okisijeni chaiyo. Izvi zvakachengeteka uye zvinosangana nezvinodiwa zvehutano.
2. Gara uchibvunza chiremba wako usati washandisa chero chinhu chinosimbisa oxygen. Chiremba wako achakuudza kana uchida oxygen yekuwedzera, pamwe nerequired flow rate (LPM) uye oxygen saturation target.
3. Chengetedza mhepo yakakwana yakatenderedza mudziyo uye chenesa kana kutsiva mafirita nguva nenguva kuti uve nechokwadi chekuti unoshanda zvakanaka.
