Chii chinonzi kuongorora ropa kwe CO2?

Kuongororwa kweropa kwe CO2 kunoyera huwandu hwekabhoni dhayokisaidhi (CO2) muropa serum, inova chikamu chemvura. Bvunzo ye CO2 inogona zvakare kunzi:

• kabhoni dhayokisaidhi bvunzo
• bvunzo ye TCO2
• yakazara CO2 bvunzo
• bicarbonate bvunzo
• bvunzo ye HCO3
• iyo CO2 bvunzo-seramu

Iwe unogona kugamuchira iyo CO2 bvunzo sechikamu chemetabhenakeri pani. Iyo metabolic pani iboka rebvunzo rinoyera maelectrolyte uye magasi eropa.

Mutumbi une maviri makuru mafomu eEC2:

• HCO3 (bicarbonate, chimiro chikuru che CO2 mumuviri)
• PCO2 (kabhoni dhayokisaidhi)

Chiremba wako anogona kushandisa bvunzo iyi kuti aone kana paine kusaenzana pakati peoxygen uye kabhoni dhayokisaidhi muropa rako kana kusaenzana kwepH muropa rako. Uku kusaenzana kunogona kuve zviratidzo zveitsvo, kufema, kana kusagadzikana kwemagetsi.

Nei kuongororwa kweropa kweCO2 kuchirairwa

Chiremba wako acharaira CO2 kuongororwa kweropa zvichienderana nezviratidzo zvako. Zviratidzo zvekusaenzana kweoksijeni uye kabhoni dhayokisaidhi kana kusaenzana kwepH zvinosanganisira:

• mweya wekufema
• kumwe kufema kunetseka
• kusvotwa
• kurutsa

Zviratidzo izvi zvinogona kunongedzera kukushomeka kwemapapu kunosanganisira kuchinjana pakati peoksijeni necarbon dioxide.

Iwe unozofanirwa kuve neyako ropa reoksijeni uye carbon dioxide mazinga anoyerwa kazhinji kana iwe uri pakurapwa kweoksijeni kana uine kumwe kuvhiyiwa.

Kutorwa kweropa

Zviratidzo zveropa zveCO2 kuongororwa kweropa zvinogona kutorwa kubva mutsinga kana tsinga.

Venipuncture ropa sampuro

Venipuncture ndiro izwi rinoshandiswa kutsanangura rakakosha ropa sampuro yakatorwa kubva mutsinga. Chiremba wako anozoraira yakapusa venipuncture ropa sampuro kana ivo vachingoda kuyera HCO3.

Kuti uwane muropa weropaini, murapi wehutano:

• inosuka saiti (kazhinji mukati megokora) nehutachiona hunouraya hutachiona
• inomonera bhanhire rakamonereka rakatenderedza ruoko rwako rwekumusoro kuti tsinga izate neropa
• zvinyoronyoro unopinza tsono mukati mutsinga uye unotora ropa muhubhu yakasungirirwa kusvika yazara
• inobvisa bhanhire rakasununguka uye tsono
• inovhara ronda rekubaya neiyo isina kuchena gauze kumisa chero kubuda ropa

Arterial ropa sampuro

Ropa gasi ongororo kazhinji chikamu cheiyo CO2 bvunzo. Kuongorora gasi reropa kunoda arterial ropa nekuti magasi uye pH mazinga mumateri akasiyana neropa venous (ropa kubva mutsinga).

Tsinga dzinotakura okisijeni mumuviri wese. Tsinga dzinotakura tsvina yemetabolism uye deoxygenated ropa kuenda kumapapu kuti ibudiswe sekabhoni dhayokisaidhi uye kune itsvo dzinopfuudzwa mumuti

Maitiro akaomesesa aya anoitwa nachiremba akadzidziswa kuwana arteri zvakachengeteka. Ropa reArterial rinowanzo kutorwa kubva mutsinga iri muchioko inonzi radial artery. Iyi ndiyo tsinga huru inowirirana nechigumwe, uko kwaunogona kunzwa kupomba kwako.

Kana, ropa rinogona kuunganidzwa kubva kune brachial arteri mugokora kana yevakadzi femari mune yekugomera. Kuti uwane arterial yeropa sampuro, murapi:

• inochenesa saiti iyi nehutachiona-hunouraya hutachiona
• zvinyoronyoro unopinza tsono mukati tsinga uye unokwevera ropa mutubhini yakasungirirwa kusvikira yazara
• inobvisa tsono
• anoshandisa kumanikidza kwakasimba pachironda kweinenge maminitsi mashanu kuti ropa ribude. (Tsinga dzinotakura ropa kumanikidziro epamusoro kupfuura mutsinga, saka zvinotora nguva yakawanda kuti ropa rigadzire kugwamba.)
• inoisa chakaputira chakakomberedza iyo punct saiti iyo inofanirwa kugara munzvimbo kwenguva inokwana awa

Maitiro ekugadzirira kuongororwa kwako kweropa

Chiremba wako anogona kukukumbira kuti utsanye, kana kurega kudya uye kunwa, usati wayedzwa ropa. Chiremba wako anogona zvakare kukukumbira kuti urege kutora mimwe mishonga usati waedzwa se corticosteroids kana antacids. Iyi mishonga inowedzera kusangana kwe bicarbonate mumuviri.

Njodzi dzekuongororwa kweropa kweCO2

Pane njodzi shomanene dzinosanganisirwa neese venipuncture uye arterial ropa bvunzo. Izvi zvinosanganisira:

• kubuda ropa zvakanyanya
• kufenda
• musoro wakareruka
• hematoma, rinova bundu reropa pasi peganda
• hutachiona panzvimbo yekubaya

Mushure mekudhonzwa kweropa, murapi wako achave nechokwadi chekuti uri kunzwa mushe uye achakuudza maitiro ekuchengeta nzvimbo yekubaya kuti uderedze mukana wehutachiona.

Mhedzisiro yebvunzo

Iyo yakajairwa renji ye CO2 ndeye 23 kusvika 29 mEq / L (milliequivalent units per litre reropa).

Iko kuongororwa kweropa kunowanzo kuyera ropa pH pamwe ne CO2 mazinga kuti uwedzere kuona chikonzero chechiratidzo chako. Ropa pH chiyero che acidity kana alkalinity. Alkalosis iri apo muviri wako mvura mvura zvakare alkaline. Acidosis, kune rumwe rutivi, ndipo apo mvura yemuviri wako yakanyanyisa.

Kazhinji, ropa rinonyanya kukosha ne pH kuyerwa kwepedyo ne7.4 mukuchengetwa nemuviri. Yakajairwa renji kubva 7.35 kusvika 7.45 inoonekwa seyakarerekera. Ropa pH kuyera risingasviki 7.35 inoonekwa seicidiki. Chinhu chinowedzera alkaline kana ropa pH yaro yakakura kudarika 7.45.

Yakadzika bicarbonate (HCO3)

Mhedzisiro yekuedzwa kwepasi bicarbonate uye yakaderera pH (isingasviki 7.35) mamiriro anonzi metabolic acidosis. Zvinowanzoitika ndeizvi:

• itsvo kutadza
• manyoka akakomba
• lactic acidosis
• pfari
• gomarara
• kushaikwa kwenguva refu kweoksijeni kubva kwakanyanya kupererwa neropa, kutadza kwemoyo, kana kuvhunduka
• chirwere cheshuga ketoacidosis (chirwere cheshuga acidosis)

Mhedzisiro yekuedzwa kwepasi bicarbonate uye yakakwira pH (inopfuura 7.45) chiitiko chinonzi kufema alkalosis. Zvinowanzoitika ndeizvi:

• hyperventilation
• kupindwa nechando
• kurwadziwa
• kushushikana

Yakakwirira bicarbonate (HCO3)

Mhedzisiro yekuedzwa kwepamusoro bicarbonate uye yakaderera pH (isingasviki 7.35) mamiriro anonzi kufema acidosis. Zvinowanzoitika ndeizvi:

• chirwere chemabayo
• chisingaperi obstructive pulmonary chirwere (COPD)
• asima
• pulmonary fibrosis
• kusvibiswa nemakemikari ane chepfu
• zvinodhaka zvinodzvinyirira kufema, kunyanya kana zvabatanidzwa nedoro
• tibhii
• kenza yemapapu
• pulmonary hypertension
• kufutisa kwakanyanya

Mhedzisiro yekuedzwa kwepamusoro bicarbonate uye yakakwira pH (inopfuura 7.45) chiitiko chinonzi metabolic alkalosis. Zvinowanzoitika ndeizvi:

• kurutsa kusingaperi
• yakaderera potasiamu mazinga
• hypoventilation, iyo inosanganisira kunonoka kufema uye kudzikira CO2 kubviswa

Maonero kwenguva refu

Kana chiremba wako awana kusaenzana kweEC2 kunoratidza acidosis kana alkalosis, ivo vachatarisa muchikonzero chekusaenzana uku ndokuchibata nenzira kwayo. Nekuti izvo zvinokonzeresa zvinosiyana, kurapwa kunogona kusanganisira musanganiswa wekuchinja mararamiro, mishonga, uye kuvhiyiwa.
