Qhov Tseem Ceeb - Cyanosis vs Hypoxia
Cyanosis thiab hypoxia yog ob yam uas yuav tsum tau kho mob sai. Cyanosis yog tus cwj pwm los ntawm lub ntsej muag daj ntawm qhov muag lossis tus nplaig thaum cov ntsiab lus deoxygenated hemoglobin hauv cov ntshav nce ntau dua 5g ib 100 ml ntawm cov ntshav. Qhov txo qis ntawm cov pa oxygen rau cov ntaub so ntswg hauv lub cev yog hu ua hypoxia. Qhov sib txawv tseem ceeb ntawm cyanosis thiab hypoxia yog cov tsos ntawm cov xim xiav nyob rau hauv cov mucous daim nyias nyias, uas yog cov cim cim ntawm cyanosis.
Hypoxia yog dab tsi?
Qhov txo qis ntawm oxygen rau cov ntaub so ntswg hauv lub cev yog hu ua hypoxia.
Caus
- Extrinsic ua rau ua rau tsis muaj oxygenation ntawm cov ntshav
- Deficiency ntawm oxygen nyob rau hauv cov huab cua raws li nyob rau hauv high altitudes
- Hypoventilation vim neuromuscular mob
- kab mob ntsws
- Kev nce hauv txoj hlab pa tsis kam lossis txo qis hauv kev ua raws li pulmonary parenchyma uas ua rau hypoventilation
- Kab mob uas cuam tshuam qhov kev nthuav tawm ntawm cov pa oxygen los ntawm cov pa ua pa
- Kev txhim kho ntawm qhov chaw pulmonary tuag lossis lub cev nqaij daim tawv uas txo qis qhov cua perfusion piv
- Venous to Arterial Shunts
- Txhua yam mob hematological uas txo cov perfusion ntawm oxygen rau cov ntaub so ntswg peripheral
- Anemia
- YNtseeg hemoglobin
- Hypovolemic mob
- Txhua yam kev cuam tshuam hauv cov hlab ntsha uas cuam tshuam cov ntshav mus rau ib cheeb tsam
- Tissue edema
- tsis muaj peev xwm ntawm cov ntaub so ntswg kom haus oxygen
- Kev hloov pauv ntawm cov qauv ntawm oxidation enzymes
- Tsis muaj cov vitamins uas ua cov cofactors rau cov enzymes
Ib qho piv txwv classic ntawm qhov xwm txheej zoo li no yog kev lom lom cyanide. Cyanide ua raws li qhov tsis tuaj yeem thim rov qab inhibitor ntawm enzyme cytochrome oxidase. Yog li oxidative phosphorylation tsis tshwm sim. Hauv Beri Beri, qhov tsis muaj vitamin B cuam tshuam rau oxidative ua pa.
Kev cuam tshuam ntawm Hypoxia ntawm lub cev
- Kev tuag
- Kev nyuaj siab ntxhov plawv
- Coma
- Kev ua haujlwm tsis txaus ntawm cov leeg
- Nyob
Oxygen Therapy
Txawm li cas los xij, kev tswj hwm cov pa oxygen tuaj yeem ua haujlwm zoo hauv kev tswj cov hypoxia. Oxygen tuaj yeem tswj hwm peb txoj hauv kev
- Muab tus neeg mob lub taub hau tso rau hauv lub tsev pheeb suab uas muaj cua nrog cov pa tiv thaiv zoo
- Tso cai rau tus neeg mob ua pa ntshiab oxygen lossis cov pa oxygen siab los ntawm lub npog ntsej muag
- Kev tswj cov pa oxygen los ntawm lub raj tso pa tawm
Daim duab 01: Kev Kho Oxygen
Kev kho Oxygen yog qhov zoo heev hauv kev kho mob ntawm hypoxia uas yog tshwm sim los ntawm qhov tsis muaj oxygen hauv huab cua. Kev tswj hwm cov pa oxygen kuj tseem tuaj yeem pab tau rau kev tswj hwm ntawm hypoxia vim hypoventilation. Tab sis txij li thaum hypoventilation tshwm sim nyob rau hauv tsub zuj zuj ntawm carbon dioxide nyob rau hauv lub circulatory system, oxygen kho ib leeg yuav tsis txhim kho cov tsos mob.
Thaum qhov ua rau hypoxia yog ib qho mob cuam tshuam rau lub ntsws ua pa los ntawm qhov kev nthuav tawm ntawm cov pa tshwm sim, kev tswj hwm cov pa tawm sab nraud yuav ua rau muaj qhov siab ntawm cov pa oxygen hauv alveoli. Yog li ntawd, lub diffusion gradient kuj nce, expediting lub zog ntawm oxygen molecules rau hauv cov ntshav. Yog li kev kho cov pa oxygen yog hom kev kho mob zoo hauv kev tswj hwm ntawm hypoxia vim kev ua pa ntawm daim nyias nyias pathologies.
Thaum muaj hypoxia vim qhov txawv txav ntawm hematological, tsis muaj dab tsi tsis ncaj ncees lawm nrog lub tshuab uas alveoli tau txais oxygen. Yog li ntawd, kev kho cov pa oxygen tsis muaj qhov chaw hauv kev tswj hwm ntawm hypoxia vim yog vim li cas vim tias nws tsis yog cov pa oxygen uas tsis zoo, tab sis cov cab kuj uas yog lub luag haujlwm rau kev tso pa tawm ntawm lub ntsws mus rau cov ntaub so ntswg peripheral. Ib yam li ntawd, yog tias cov kab mob nyob hauv cov ntaub so ntswg, ua rau lawv tsis muaj peev xwm siv cov pa oxygen xa mus rau lawv los ntawm cov ntshav, kev kho cov pa oxygen yuav tsis muaj txiaj ntsig hauv kev kho tus neeg mob tus mob.
Cyanosis yog dab tsi?
Lub ntsej muag daj ntawm cov mucous daim nyias nyias vim qhov ntau ntawm deoxygenated hemoglobin hauv cov ntshav capillary hu ua cyanosis. Txhua qhov concentration ntawm deoxygenated hemoglobin uas ntau dua 5g ib 100 ml ntawm cov ntshav hlab ntsha yog tsim nyog los ua rau qhov kev kuaj mob no.
Qhov tseeb nthuav yog, cov neeg mob anemic yeej tsis ua hypoxic vim tias lawv cov hemoglobin concentration yog qis dua qhov xav tau deoxygenated hemoglobin concentration kom ua rau cyanosis. Ntawm qhov tod tes, cov neeg mob polycythemic muaj kev nyiam ntau dua los tsim cyanosis txawm tias nyob rau hauv cov xwm txheej ib txwm muaj vim tias cov ntshav hemoglobin ntau dhau.
Nyob ntawm qhov chaw ntawm cov xim daj, cyanosis tau muab faib ua pawg raws li
Central Cyanosis
Qhov ua rau lub hauv nruab nrab cyanosis yog qhov shunting ntawm cov ntshav venous mus rau hauv cov kab mob hauv lub cev xws li nyob rau hauv txoj cai-sab laug plawv shunts. Central cyanosis tshwm ntawm tus nplaig.
Peripheral Cyanosis
Peripheral cyanosis pom ntawm tes thiab ko taw. Nws yog tshwm sim los ntawm tej yam mob uas ua rau stasis ntawm cov ntshav nyob rau hauv peripheries. Vasoconstriction ntawm cov hlab ntsha hauv cheeb tsam, congestive cardiac tsis ua hauj lwm, Raynaud's kab mob thiab raug rau qhov kub thiab txias yog feem ntau ua rau peripheral cyanosis.
Dab tsi yog qhov zoo sib xws ntawm Cyanosis thiab Hypoxia?
Ob qho xwm txheej no yog qhov tshwm sim ntawm kev hloov pauv hauv qhov concentration ntawm cov pa roj ua pa
Qhov txawv ntawm Cyanosis thiab Hypoxia yog dab tsi?
Cyanosis vs Hypoxia |
|
| Cyanosis yog xim daj ntawm cov mucous daim nyias nyias vim muaj ntau dhau ntawm deoxygenated hemoglobin hauv cov ntshav capillary. | Hypoxia yog qhov tsis txaus ntawm cov pa oxygen nkag mus rau cov ntaub so ntswg. |
| Ib lub ntsej muag daj daj tshwm nyob rau hauv qhov chaw los yog hauv tus nplaig. | Tsis muaj qhov pom sab nraud hloov xim. |
Summary – Cyanosis vs Hypoxia
Hypoxia thiab cyanosis tuaj yeem suav tias yog ob qhov kev kho mob uas tshwm sim vim kev ua txhaum ntawm cov ntshav mus rau ntau thaj tsam ntawm lub cev. Hypoxia uas yog qhov txwv tsis pub muaj oxygen rau hauv cov ntaub so ntswg ntawm lub cev tag nrho blunts oxidative ua pa. Cyanosis yog vim qhov nce hauv cov concentration ntawm deoxygenated hemoglobin hauv cov ntshav. Qhov no yog qhov txawv ntawm cyanosis thiab hypoxia.
