Calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 58 mm Hg. Assume hemoglobin is 50% sat
svetlana [45]

Answer:

0.8988

Explanation:

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

YO_2=\frac{(pO_2)^n}{(p50)^n+(pO_2)^n}

now putting the values

YO_2= \frac{58^3}{28^3+58^3}

= \frac{195112}{21952+195112}

=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
