calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 44 mm hg . assume hemoglobin is 50 % saturated with oxygen at a partial pressure of 26 mm hg and that the hill coefficient is 3.



Answer :

The fractional saturation for hemoglobin is 0.8290 when the partial pressure of oxygen is 44 mm hg.

The fractional saturation for hemoglobin can be described as the ratio of the total hemoglobin which is oxygenated.

The fractional saturation for hemoglobin can be calculated by using the following formula;

FS = (partial pressure of oxygen)^n ÷ (partial pressure of oxygen at which hemoglobin is 50% saturated)^n + (partial pressure of oxygen)^n

Here n represents the hill coefficient

Substituting the values in this formula to determine the fractional saturation;

Fractional saturation = (44)³ / (26)³ + (44)³

Fractional saturation = 85,184 / 17,576 + 85,184

Fractional saturation = 85,184 / 102,760

Fractional saturation = 0.8290

Therefore, the fractional saturation for hemoglobin is calculated to be 0.8290 when the partial pressure of oxygen is 44 mm hg.
