Shifting of the oxygen dissociation curve to the right indicate
A rise in temperature or a fall in pH shifts the curve to the right.When the curve is shifted in this direction, a higher PO2 is required for hemoglobin to bind a given amount of O2.By decreasing o2 affinity more O2 is released to the tissue.
