What is the P/F ratio? Pb = 700 FIO2 @ 85% SpO2 = 90%   ABG pH 7.48 CO2 55 HCO3 35 O2 52   SV = 44 BP = 135/97 Hb = 18

What is the A-a gradient? Pb = 700 FIO2 @ 85% SpO2 = 90%   ABG pH 7.48 CO2 55 HCO3 35 O2 52   SV = 44 BP = 135/97 Hb = 18

If the patient above has an arterial PO2 of 90 mm Hg, what is the A–a gradient? 

As the hydrolysis of CO2 continues, HCO3 − ions begin to accumulate in the erythrocyte. To maintain a consistent concentration across the cell membrane, some of these anions diffuse outward into the plasma. Because the erythrocyte is not freely permeable by cations, electrolytic equilibrium must be maintained by way of an inward movement of anions. This migration is achieved by _______________ from the plasma into the erythrocyte?
