WebThe bicarbonate shift well counterbalanced to the Cl- shift. As the hematocrit was decreased, the amount of CO2 released per mol of hemoglobin increased, while the change in intracellular bound CO2 concentration decreased. That is, the intracellular bound CO2 became higher in the lower hematocrit blood than in the higher hematocrit one. Web20 de nov. de 2024 · Regular pulse oximetry cannot be used to detect COHb. Multiwavelength pulse oximetry may be a good screening tool for carbon monoxide poisoning in a large number of patients if the carbon monoxide hemoglobin saturation (SpCO) reading is less than 15%.
