Uplоаd аn imаge оf yоur graph. On the O2 binding curve shown in this image, draw a solid line indicating how the curve would look if the blood [CO2] increased. Draw a dashed line indicating how the curve would look if the pH increased. Draw a dotted line showing how the curve would look if the 2,3-BPG levels increased. Be sure that we can distinguish your dashed and dotted lines. Image Description Fractional saturation curve for the partial pressure of oxygen, with the Y-axis labeled as Y (fractional saturation) and the X-axis labeled as pO2 in millimeters of mercury.
