Why?The equation describing the linear relationship between hemoglobin concentration and absorbance at 520 nm is y=0.0523x+0.011. If the absorbance value is 0.6, calculate the % hemoglobin in whole blood.A 50-year-old man came to the emergency department after returning from foreign travel. His symptoms included persistent diarrhea (over the past 3 days) and rapid respiration (tachypnea). Blood gases were drawn with the following results: pH 7.21 pco2 19 mm Hg po2 96 mm Hg HCO3 − 7 mmol/L SO2 96% (calculated) (reference range, >95%) Why is the HCO3 − level so low? Why does the patient have rapid respiration?
