Txo lub cev kub (hypothermia) ua rau a sab laug ua haujlwmhauv oxyhemoglobin dissociation nkhaus, piv txwv li ua kom hemoglobin affinity rau oxygen, thaum lub cev kub (hyperthermia) ua rau txoj cai hloov, i.e. txo hemoglobin affinity rau oxygen [8].
Dab tsi yog qhov oxyhemoglobin dissociation nkhaus qhia peb?
Cov oxyhemoglobin dissociation nkhaus (OHDC) qhia kev sib raug zoo ntawm oxygen saturation ntawm hemoglobin (Sao 2) thiab ib nrab siab ntawm arterial oxygen (Pao 2) … Nws tsis ncaj qha qhia txog cov hlab ntsha hemoglobin saturation, ntsuas raws li oxygen saturation los ntawm pulse oximetry (Spo2).
Puas PaO2 nce nrog hypothermia?
Qhov kev soj ntsuam qhov cuam tshuam ntawm cov teebmeem no yog qhov tseeb: Thaum twg peb ntsuas cov pa oxygen tension (PaO2) thiab tsis kho cov txiaj ntsig tam sim no (hypothermic) lub cev kub, muaj tseeb PaO2 tsis nce thaum lub sijhawm. txias, tab sis qhov pom qhov nce hauv kev ntsuas PaO2 tsuas yog vim qhov tseeb tias lub cev kub thiab qhov …
Dab tsi cuam tshuam rau oxyhemoglobin dissociation nkhaus?
Cov pa oxygen-hemoglobin dissociation nkhaus tuaj yeem hloov chaw xws li kev sib raug zoo rau cov pa oxygen hloov pauv. Cov yam ntxwv uas hloov qhov nkhaus suav nrog hloov pauv hauv cov pa roj carbon dioxide concentration, ntshav kub, ntshav pH, thiab cov concentration ntawm 2, 3-diphosphoglycerate (2, 3-DPG)
kub cuam tshuam li cas ntawm cov pa oxygen dissociation nkhaus?
Kub: Kev nce ntawm qhov kub thiab txias hloov qhov nkhaus mus rau sab xis, thaum qhov txo qis hauv qhov kub hloov qhov nkhaus mus rau sab laug. Ua kom qhov kub thiab txias denatures qhov kev sib raug zoo ntawm oxygen thiab hemoglobin, uas ua rau kom cov pa oxygen thiab hemoglobin thiab txo cov concentration ntawm oxyhaemoglobin.
