Menene gwajin jini na CO2?

Gwajin jini na CO2 yana auna adadin carbon dioxide (CO2) a cikin jinin, wanda shine sashin ruwa na jini. Hakanan ana iya kiran gwajin CO2:

• gwajin carbon dioxide
• gwajin TCO2
• duka gwajin CO2
• gwajin bicarbonate
• gwajin HCO3
• a CO2 gwajin-magani

Kuna iya karɓar gwajin CO2 a matsayin ɓangare na rukunin rayuwa. Metungiyar rayuwa ita ce ƙungiyar gwajin da ke auna lantarki da iskar gas.

Jiki yana ƙunshe da manyan siffofin CO2 guda biyu:

• HCO3 (bicarbonate, babban nau'in CO2 a jiki)
• PCO2 (carbon dioxide)

Likitanku na iya amfani da wannan gwajin don tantancewa idan akwai rashin daidaituwa tsakanin oxygen da carbon dioxide a cikin jininku ko rashin daidaiton pH a cikin jininku. Wadannan rashin daidaituwa na iya zama alamun koda, na numfashi, ko rashin lafiyar rayuwa.

Me yasa aka umarci gwajin jini na CO2

Likitanku zai ba da umarnin gwajin jini na CO2 dangane da alamunku. Alamomin rashin daidaiton oxygen da carbon dioxide ko rashin daidaiton pH sun hada da:

• karancin numfashi
• sauran matsalolin numfashi
• tashin zuciya
• amai

Wadannan alamun na iya nunawa ga cutar huhu wanda ya shafi musayar tsakanin oxygen da carbon dioxide.

Kuna buƙatar auna matakan oxygen da jinin carbon dioxide akai-akai idan kuna kan maganin oxygen ko kuma samun wasu tiyata.

Yadda ake daukar samfurin jini

Ana iya ɗaukar samfurin jini don gwajin jini na CO2 daga wata jijiya ko jijiya.

Venipuncture samfurin jini

Venipuncture kalma ce da ake amfani da ita don bayyana samfurin jini na asali wanda aka ɗauka daga jijiya. Likitan ku zai yi odar samfurin jini mai sauki idan suna son auna HCO3 kawai.

Don samun samfurin jini, mai ba da lafiya:

• tsabtace wurin (sau da yawa a cikin gwiwar hannu) tare da maganin kashe ƙwayoyin cuta
• yana nade bandir na roba a hannunka na sama don yasa jijiya ta kumbura da jini
• a hankali saka allura a cikin jijiyar kuma tara jini a cikin bututun da aka haɗe har sai ya cika
• yana cire bandin roba da allura
• yana rufe raunin huda da fatar bakararre don tsayar da duk wani jini

Samfurin jinin jini

Binciken gas na jini galibi wani ɓangare ne na gwajin CO2. Nazarin iskar gas yana buƙatar jinin jini saboda gas da matakan pH a cikin jijiyoyin sun bambanta da na jini (jini daga jijiya).

Arteries suna ɗaukar oxygen a cikin jiki duka. Jijiyoyi suna ɗauke da sharar rayuwa da kuma deoxygenated jini zuwa huhu don fitar da su kamar carbon dioxide da zuwa kodan da za a barsu cikin fitsari.

Wannan hanyar da ta fi rikitarwa ana aiwatar da ita ne ta hanyar kwararren likita da aka horar don samun damar isa ga jijiyoyi. Jinin jijiya yawanci ana ɗauke shi daga jijiya a cikin wuyan hannu wanda ake kira radial artery. Wannan shine babbar jijiya a layi tare da babban yatsa, inda zaku ji bugun ku.

Ko kuma, ana iya tara jini daga jijiyar zuciya a gwiwar hannu ko jijiyoyin mata a cikin duri. Don samun samfurin jini na jini, mai yin aikin:

• tsabtace shafin tare da maganin kashe kwayoyin cuta
• a hankali saka allura a cikin jijiyar kuma zana jini a cikin bututun da ke haɗe har sai ya cika
• cire allura
• Ana matsa lamba sosai ga rauni na aƙalla aƙalla minti biyar don tabbatar da zubar jini. (Arteries yana ɗaukar jini a matsi mafi girma fiye da jijiyoyi, don haka yana ɗaukar ƙarin lokaci kafin jini ya zama gudan jini.)
• yana sanya matsatststen kunu a kusa da wurin hujin da zai buƙaci zama aƙalla aƙalla sa'a guda

Yadda ake shirya wa gwajin jininka

Likitanka na iya tambayarka ka yi azumi, ko ka daina ci da sha, kafin gwajin jini. Hakanan likitan ku na iya tambayar ku ku daina shan wasu magunguna kafin gwajin kamar su corticosteroids ko maganin kashe kuɗaɗe. Wadannan kwayoyi suna kara yawan bicarbonate cikin jiki.

Rashin haɗarin gwajin jini na CO2

Akwai ƙananan haɗari waɗanda ke haɗuwa da duka venipuncture da gwajin jini na jijiyoyin jini. Wadannan sun hada da:

• yawan zubar jini
• suma
• rashin haske
• hematoma, wanda shine dunkulen jini a ƙarƙashin fata
• kamuwa da cuta a wurin huda

Bayan zub da jini, maikitanka zai tabbatar da cewa kana jin daɗi kuma zai gaya maka yadda zaka kula da wurin huda don rage damar kamuwa da cutar.

Sakamakon gwaji

Matsakaicin yanayi na CO2 shine 23 zuwa 29 mEq / L (raka'a masu haɗuwa a kowace lita ta jini).

Gwajin jini yakan auna pH na jini tare da matakan CO2 don ƙarin ƙayyade dalilin alamunku. PH na jini shine ma'aunin acidity ko alkalinity. Alkalosis shine lokacinda ruwan jikinku yayi yawa. Acidosis, a gefe guda, shine lokacin da ruwan jikinki yayi yawa.

Yawanci, jini yana da ɗan asali tare da ma'aunin pH na kusa da 7.4 wanda jiki ke kiyaye shi. Matsakaicin al'ada daga 7.35 zuwa 7.45 ana ɗaukar tsaka tsaki. Gwajin pH na jini ƙasa da 7.35 ana ɗaukarsa acidic. Wani abu yafi alkaline lokacin da jinin pH ya fi girma fiye da 7.45.

Baramin ma'aunin bicarbonate (HCO3)

Sakamakon gwaji na low bicarbonate da low pH (kasa da 7.35) yanayi ne da ake kira metabolism acidosis. Abubuwan da ke faruwa sune:

• gazawar koda
• zawo mai tsanani
• lactic acidosis
• kamuwa
• ciwon daji
• rashin isashshen oxygen daga tsananin karancin jini, gazawar zuciya, ko gigicewa
• mai ciwon sukari ketoacidosis (ciwon sukari acidosis)

Sakamakon gwaji na ƙananan bicarbonate da babban pH (fiye da 7.45) yanayin ne da ake kira alkalosis na numfashi. Abubuwan da ke faruwa sune:

• hauhawar jini
• zazzaɓi
• zafi
• damuwa

Babban bicarbonate (HCO3)

Sakamakon gwaji na babban bicarbonate da low pH (ƙasa da 7.35) yanayi ne da ake kira acidosis na numfashi. Abubuwan da ke faruwa sune:

• namoniya
• cututtukan huhu na huɗawa (COPD)
• asma
• huhu na huhu
• bayyanar da sinadarai masu guba
• magungunan da ke danne numfashi, musamman idan aka haɗasu da barasa
• tarin fuka
• ciwon huhu na huhu
• hauhawar jini
• tsananin kiba

Sakamakon gwaji na babban bicarbonate da babban pH (sama da 7.45) yanayi ne da ake kira metabolism alkalosis. Abubuwan da ke faruwa sune:

• amai na kullum
• ƙananan matakan potassium
• hypoventilation, wanda ya shafi jinkirin numfashi da rage kawar da CO2

Hangen nesa

Idan likitanka ya sami rashin daidaituwa na CO2 yana nuna acidosis ko alkalosis, za su bincika cikin dalilin wannan rashin daidaito kuma su bi da shi yadda ya dace. Saboda dalilan sun bambanta, magani na iya haɗawa da haɗuwa da canje-canje na rayuwa, magunguna, da tiyata.
