Magasi eropa
Magasi eropa chiyero chekuti yakawanda sei oxygen uye carbon dioxide iri muropa rako. Ivo zvakare vanoona acidity (pH) yeropa rako.
Kazhinji, ropa rinotorwa kubva mutsinga. Mune zvimwe zviitiko, ropa rinobva mutsinga rinogona kushandiswa (venous blood gas).
Kazhinji kazhinji, ropa rinogona kutorwa kubva kune imwe yetsinga dzinotevera:
- Radial arteri muchiuno
- Artery yemukadzi mune iyo groin
- Brachial arteri muruoko
Anopa hutano anogona kuyedza kutenderera kune ruoko asati atora muyenzaniso weropa kubva munzvimbo yechiuno.
Mupiki anoisa tsono kuburikidza neganda kupinda mutsinga. Muenzaniso wacho unokurumidza kutumirwa kurabhoritari kunoongororwa.
Iko hakuna kugadzirira kwakakosha. Kana iwe uri pakurapwa kweoksijeni, iko kukosheswa kweoksijeni kunofanirwa kuramba kuripo kwemaminetsi makumi maviri bvunzo usati waitwa.
Udza mupiki wako kana iwe uri kutora chero mishonga-yekuchera ropa mishonga (anticoagulants), kusanganisira aspirin.
Kana tsono ikaiswa kukweva ropa, vamwe vanhu vanonzwa kurwadziwa zvine mwero. Vamwe vanongonzwa kubaya kana kubaya. Mushure meizvozvo, panogona kuve nekurohwa kana kupwanya zvishoma. Izvi zvinokurumidza kuenda. Marwadzo uye kusagadzikana zvinowanzo kuve zvakanyanya kupfuura kutora ropa kubva mutsinga.
Muedzo unoshandiswa kuongorora zvirwere zvekufema uye mamiriro anokanganisa mapapu. Inobatsira kuona kugona kweoksijeni kurapa kana isiri-inoparadza mweya (BiPAP). Muedzo unopawo ruzivo nezve muviri weacid / base balance, iyo inogona kuburitsa pachena zvakakosha nezve mapapu neitsvo basa uye nemuviri wemuviri metabolic mamiriro.
Maitiro pagungwa.
- Kudzvinyirira kwakasarudzika kweoksijeni (PaO2): 75 kusvika 100 mamirimita emekiyuri (mm Hg), kana 10.5 kusvika 13.5 kilopascal (kPa)
- Kumanikidza kudzvanywa kwekabhoni dhayokisaidhi (PaCO2): 38 kusvika 42 mm Hg (5.1 kusvika 5.6 kPa)
- Ropa reropa pH: 7.38 kusvika 7.42
- Oxygen saturation (SaO2): 94% kusvika 100%
- Bicarbonate (HCO3): 22 kusvika 28 milliequivalents pa litre (mEq / L)
Pakukwirira kwemamirioni mazana matatu (900 metres) uye zvichikwira, kukosha kweoksijeni kwakadzikira.
Zvakajairika kukosha masenduru anogona kusiyana zvishoma pakati pemarabhoritari akasiyana. Mamwe marabhoritari anosanganisira zviyero zvakasiyana. Taura nachiremba wako nezve zvinorehwa nemimwe miedzo yako.
Zviitiko zvisina kujairika zvinogona kunge zvichikonzerwa nemapapu, itsvo, chirwere chemetabolism, kana mishonga. Kukuvara mumusoro kana mumutsipa kana kumwe kukuvara kunokanganisa kufema kunogona zvakare kutungamira kune zvisina kujairika mhedzisiro.
Pane njodzi shoma kana maitiro acho aitwa nemazvo. Tsinga uye tsinga zvinosiyana muhukuru kubva kumunhu kuenda kune mumwe uye kubva kune rimwe divi remuviri kuenda kune rimwe. Kutora ropa kubva kune vamwe vanhu kunogona kunge kwakaoma kupfuura kubva kune vamwe.
Dzimwe njodzi dzinosangana nekutorwa kweropa idiki, asi dzinogona kusanganisira:
- Kufenda kana kunzwa kushaya musoro
- Multiple punctures yekutsvaga mitsipa yeropa
- Hematoma (kuwanda kweropa pasi peganda)
- Kuwedzera kubuda ropa
- Utachiona (hushoma njodzi chero nguva ganda parinovhunika)
Kuongorora kweropa reropa; ABG; Hypoxia - ABG; Kukundikana kwekufema - ABG
- Ropa magasi bvunzo
