Fungidzira kuti mumwe munhu ari pedyo newe, pamwe mwana mudiki ane asthma kana munhu mukuru, anongoerekana asisakwanise kufema, obatwa nepfari, uye otanga kudzipwa. Tingatya sei panguva yakadaro? Saka, nhasi tiri kutaura nezvekurapa kwakakosha kunogona kushandiswa navanachiremba muzvipatara kana paine dambudziko rakadaro. Izvi zvinonzi Heliox. Pane dzimwe nguva apo uku kunogona kuva kurapwa kunoponesa hupenyu.
Zvichitaurwa zviri nyore, chii chinonzi Heliox?
Heliox musanganiswa wemagasi maviri, helium neokisijeni. Inoshandiswa nevashandi vehutano, kureva vanachiremba, kurapa varwere vane matambudziko ekufema zvakanyanya, kunyanya mumamiriro ezvinhu enjodzi. Basa rayo guru nderekuderedza simba rinodiwa nemuviri kuti ufeme.
Zvino tarisai, mweya watinofema une oxygen inosvika 21% uye nitrogen inosvika 78%. Kunyangwe muchipatara, oxygen inopihwa seoxygen chaiyo kana kuti inosanganiswa nenitrogen. Asi pano, helium gasi ine hunyanzvi hwakakosha. Helium igesi rakareruka kupfuura nitrogen.
Kuti tinzwisise izvi, ngatitorei muenzaniso mudiki. Fungidzira kuti nzira yako yekufema (nzira yekufema) yakamanikana nekuda kwechikosoro, asthma, kana chimwe chikonzero. Zvakafanana nepaipi yemvura yakavharika. Zvino, kana ukaedza kusunda mvura yakakora, sehuchi, kuburikidza nepaipi iyi yakavharika, zvingave zvakaoma sei? Unofanira kuisa simba rakawanda. Gasi reNitrogen rinorema zvishoma. Asi kana ukaedza kusunda mvura yakapfava semvura kuburikidza nepaipi iyoyo? Inoyerera zviri nyore. Gasi reHelium rakareruka semvura. Naizvozvo, helium inobatsira kutakura okisijeni zviri nyore kuburikidza nenzira dzakavharika uye dzakamanikana kuenda kumapapu.
Helium, kufanana nenitrogen, i "gasi risina simba". Izvi zvinoreva kuti haishande nezvimwe zvinhu mumuviri. Muviri unongotora okisijeni kubva mumusanganiswa uyu wobva wafema helium zvakare. Izvi zvinoreva kuti helium ingori "mota" inotakura okisijeni kuenda kumapapu.
Heliox inoshandiswa rini?
Chinhu chakakosha ndechekuti Heliox haisi mushonga wechirwere. Asi, itsigiro inopiwa kuti murwere agare akasimba kusvika mamwe marapirwo (semuenzaniso, mishonga yeasthma) ashanda uye mamiriro emurwere avandudzika. Zvakafanana nekupa munhu mvura inoyerera kana achinyura. Zvinobatsira kuponesa hupenyu hwake, achimirira kuti timu yekuponesa isvike. Tafura iri pazasi inoratidza mamwe emamiriro makuru ayo Heliox inoshandiswa.
| Mamiriro | Tsananguro iri nyore |
|---|---|
| Kurwiswa kwakanyanya kweasthma (Status Asthmaticus) | Kana nzira dzekufema dzikanyanya kutetepa kana munhu aine chirwere cheasthma chakakomba chisingadzorwi nemishonga yakajairika uye chinogona kuisa upenyu panjodzi. |
| Kuvharirwa kweNzira Dzemhepo | Kana nzira yekufema yavharwa nebundu kana chimwe chinhu (semuenzaniso chidimbu chechikafu) chakamira. |
| Kuwedzera kweCOPD (chirwere chemapapu chisingaperi) | Kana varwere veCOPD vachiomerwa zvakanyanya nekufema nekuda kwechimwe chikonzero chakadai sehutachiona. |
| ARDS (Acute Respiratory Distress Syndrome) | Chirwere chekuti mapapu anokuvara nekuda kwehutachiona hwakaipisisa kana tsaona uye anozadzwa nemvura kusvika padanho rekuti kufema hakuchakwanisike. |
| Stridor mushure mekubuda kwemvura | Kana chubhu yekufema ikabviswa, semushure mekuvhiyiwa, uye paine ruzha rwekufemera pakufema nekuda kwekuzvimba pahuro. |
| Kurwara Kwekudzikamisa Kunzwa Kwepfungwa ("The Bends") | Kana vanhu vanonyura mumvura yakadzika vachibuda pachena nekukurumidza, gasi renitrogen rinoungana muropa ravo rinoshanduka kuita maburi. |
Kurapwa uku kunopiwa sei?
Kune nzira dzakasiyana-siyana dzekurapa Heliox. Chiremba ndiye achasarudza zvichienderana nemamiriro emurwere.
- Kuburikidza neVentilator: Nzira iyi inoshandiswa kana murwere asina chaanoziva uye kufema kunopihwa nemuchina kana asingakwanise kufema ega.
- Kuburikidza neMask yeChiso:Inopihwa kuburikidza nemasiki yakakosha inokwana pamhino nemuromo zvemurwere.
- Kuburikidza nekanzuru yemhino: Inopihwa kuburikidza nechubhu diki inoiswa pasi pemhino.
Chiremba kana nyanzvi yezvekufema inochinja huwandu hwehelium neokisijeni zvichienderana nezvinodiwa nemurwere. Misanganiswa inowanzo shandiswa ndeye 70% helium/30% oxygen kana 60% helium/40% oxygen.
Ndezvipi zvakanakira nezvakaipa zveizvi?
Zvakanakira
Chinhu chikuru chakanakira izvi ndechekuti, sezvandambotaura, chinoderedza simba rinodiwa nemuviri kuti ufeme. Patinoomerwa nekufema, tsandanyama dzechipfuva nedzemudumbu dzinoshanda nesimba. Izvi zvinoderedza simba iroro uye zvinopa muviri zororo. Zvinoderedzawo kuvharika kwemhepo inoyerera nemhepo yakamanikana.
Zvakashata
Dambudziko guru nderekuti kurapwa uku kunoda michina yakakosha nevashandi vakadzidziswa kuti vape. Kuyerwa uye mamiriro emichina inowanzo shandiswa kupa okisijeni zvinogona kuchinja pakupa heliox. Saka, vanachiremba nevashandi vanofanirwa kuziva zvizere nezvekuchinja uku.
Asi semurwere, hauna chikonzero chekutya izvi. Vanachiremba vanoziva izvi, uye chero bedzi kurapwa uku kuchiitwa pasi pehutungamiriri hwavo, njodzi kumurwere ishoma kwazvo.
Kurapwa uku kunoitwa kusvika murwere akwanisa kufema zvakanaka ari ega kana kuti anogona kuendeswa ku oxygen therapy yenguva dzose. Kuti kupora kunoitika nekukurumidza sei zvinoenderana nekuti chirwere chiripo (semuenzaniso, asthma) chinodzorwa nekukurumidza sei.
Mharidzo Yekuenda Nayo Kumba
- Heliox musanganiswa wehelium nemweya weokisijeni. Inoshandiswa muzvipatara kune vanhu vane matambudziko ekufema zvakanyanya.
- Izvi zvinoshanda nekubatsira kutakura okisijeni zviri nyore kuburikidza nenzira dzakamanikana dzemhepo kuenda kumapapu, sezvo gasi rehelium rakareruka pane nitrogen.
- Uku hakusi mushonga wechirwere, asi mushonga wenguva pfupi unobatsira murwere panguva yekukurumidzira, senge asthma yakanyanya kana kuvharika kwemhepo.
- Izvi zvinoitwa pasi pekutarisirwa kwachiremba, nevashandi vakadzidziswa vachishandisa michina yakakosha.
- Kana iwe kana mumwe munhu waunoziva ari kusangana nematambudziko makuru ekufema, chinhu chakanakisa chekuita nekukasika ndechekuenda naye kuEmergency Treatment Unit (ETU) yechipatara chiri pedyo, uko vanachiremba vachakupa kurapwa kwakakodzera.
