Hemoglobin zvigadzirwa

Hemoglobin zvigadzirwa zvinoshandurwa mafomu ehemoglobin. Hemoglobin ipuroteni mumasero matsvuku eropa ayo anotamisa okisijeni uye kabhoni dhayokisaidhi pakati pemapapu nematumbu emuviri.

Chinyorwa ichi chinokurukura nezve muyedzo unoshandiswa kuona uye kuyera huwandu hwezvinobva muhemoglobin muropa rako.

Muedzo unoitwa uchishandisa tsono diki kutora sampuro yeropa kubva mutsinga kana tsinga. Muenzaniso unogona kutorwa kubva mutsinga kana arteri muchiuno, kugomera, kana ruoko.

Ropa risati radhonzwa, mupi wezvehutano anogona kuyedza kutenderera kune ruoko (kana chiuno chiri saiti). Mushure mekudhonzwa kweropa, kumanikidzwa kunoiswa panzvimbo yekubaya kwemaminitsi mashoma kunomisa kubuda kweropa.

Hapana gadziriro inokosha inodiwa.

Kune vana, zvinogona kubatsira kutsanangura kuti bvunzo ichanzwa sei uye nei ichiitwa. Izvi zvinogona kuita kuti mwana anzwe kusatya.

Unogona kunzwa kurwadziwa kushoma kana kurumwa kana tsono yaiswa. Iwe unogona zvakare kunzwa kumwe kurovera panzvimbo iyi mushure mekudhonzwa kweropa.

Iyo carboxyhemoglobin bvunzo inoshandiswa kuongorora carbon monoxide chepfu. Inoshandiswa zvakare kuona shanduko muhemoglobin inogona kukonzeresa kubva kune mimwe mishonga. Mamwe makemikari kana madhiragi anogona kuchinja hemoglobin saka haichashande nemazvo.

Maitiro asina kujairika ehemoglobin anosanganisira:

• Carboxyhemoglobin: Iyo isina kujairika fomu yehemoglobin iyo yakanamatira kune kabhoni monoxide pane oxygen kana kabhoni dhayokisaidhi. Huwandu hwerudzi urwu hwehemoglobin isina kujairika inodzivirira kufamba kwakajairwa kweoksijeni neropa.
• Sulfhemoglobin: Maitiro asina kujairika ehemoglobin asingakwanise kutakura oxygen. Zvinogona kukonzerwa nemimwe mishonga yakadai sedapsone, metoclopramide, nitrate kana sulfonamides.
• Methemoglobin: Dambudziko rinoitika kana simbi inova chikamu chehemoglobin yashandurwa kuti isatakure oxygen zvakanaka. Mimwe mishonga uye mamwe macomputer akadai senitriti akaunzwa muropa anogona kukonzera dambudziko iri.

Aya anotevera maitiro anomiririra chikamu chehemoglobin zvigadzirwa zvichibva pane yakazara hemoglobin:

• Carboxyhemoglobin - isingasviki 1.5% (asi inogona kunge yakakwira se9% mune vanoputa)
• Methemoglobin - isingasviki 2%
• Sulfhemoglobin - isingaonekwe

Zvakajairika kukosha masenduru anogona kusiyana zvishoma pakati pemarabhoritari akasiyana. Taura nemupi wako nezve zvinorehwa nemimwe miedzo yako.

Iyi mienzaniso iripamusoro inoratidza zviyero zvakajairika zvemhedzisiro yeiyi bvunzo. Mamwe marabhoritari anoshandisa zviyero zvakasiyana kana anogona kuyedza mienzaniso dzakasiyana.

Huwandu hwehuwandu hwehemoglobin zvigadzirwa zvinogona kutungamira kumatambudziko makuru ehutano. Mafomu akachinjika ehemoglobin haabvumidze okisijeni kufambiswa nemazvo nemuviri. Izvi zvinogona kutungamira kurufu rwekufa.

Aya anotevera maitiro, kunze kwesulfhemoglobin, anomiririra huwandu hwehemoglobin zvigadzirwa zvichibva pane yakazara hemoglobin.

Carboxyhemoglobin:

• 10% kusvika 20% - zviratidzo zve carbon monoxide chepfu zvinotanga kuoneka
• 30% - yakaoma carbon monoxide chepfu iripo
• 50% kusvika 80% - mhedzisiro inouraya carbon monoxide chepfu

Methemoglobin:

• 10% kusvika 25% - mhedzisiro yebhuruu ganda ganda (cyanosis)
• 35% kusvika 40% - zvinoguma nekufema kwekufema uye nemusoro
• Kupfuura 60% - kunoguma kunetesa uye kurara
• Kupfuura 70% - zvinogona kukonzera kufa

Sulfhemoglobin:

• Maitiro e10 gramu pa deciliter (g / dL) kana 6.2 millimoles pa litre (mmol / L) inokonzeresa ruvara rweganda bhuruu nekuda kwekushayikwa kwe oxygen (cyanosis), asi usakonzere zvinokuvadza nguva zhinji.
