Calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 58 mm hg. assume hemoglobin is 50% saturated with oxygen at a partial pressure of 28 mm hg and that the hill coefficient is 3. express your answer to two significant figures.

0.8988

Explanation:

To calculate the fractional saturation of hemoglobin , the formula used is

YO_2=

now putting the values

YO_2=

=

=0.8988

Therefore, fractional saturation of hemoglobin= 0.8988

where

YO_2= fractional saturation of hemoglobin

pO_2= partial pressure of oxygen

p50= is the pO_2 at which hemoglobin is 50% saturated
