What is meant by oxygen saturation? Can we achieve 100% oxygen saturation of hemoglobin without a hyperbaric chamber?

Expert Solution

Oxygen saturation refers to the maximum amount of oxygen that can be transported by the 100 mL of blood. In normal condition of 20 mL of oxygen by 100 mL of blood.
The oxygen can be occurred either as diffusion or bind with plasma protein or bind with Hb. The binding with Hb is indicated by the oxygen saturation curve.
The saturation of blood depends on the partial pressure of the individual gases.
The saturation can reach 100% at a pressure above 17kPa or 128 mmHg that is with an increase in the partial pressure of the oxygen saturation also increases. No further increase in saturation can be obtained with increase partial pressure further.
Also, an increase in breathing at an area which is having a higher concentration of oxygen will increase the partial pressure of oxygen thus there will be an increase in oxygen saturation.
The hyperbaric chamber uses the principle of increasing the oxygen dissolving rate into plasma by increasing atmospheric pressure.
Thus higher atmospheric pressure required for increasing saturation. At a higher altitude with higher atmosphere pressure 100% saturation can be acquired.

Draw an oxygen saturation curve for hemoglobin (pressure of O2 versus saturation (y)) with physiological levels of CO2 and 2,3-BPG at biological pH. Now using arrows to indicate which direction it moves, draw the shift in this curve when: a) There is a decrease in CO2 b) There is an increase in 2,3-BPG c) There is an increase in pH d) Hemoglobin experiences a loss of quaternary structure (breaks up into monomers)

1. What is the approximate hemoglobin O2 saturation of a blood sample that contains 10 g Hb/100 ml blood and has an O2 content of 10 ml O2/100 ml blood (ignore physically dissolved O2)? Show work 2. About 40% of Ca2+ in the blood is bound to plasma proteins, such as albumin. The [Ca2+] in Bowman’s Capsule is ~ 3 mEq/l, whereas its concentration in the plasma is ~ 5 mEq/l. Why the difference in [Ca2+] between these two compartments?...

Adult hemoglobin (iron-containing protein) can carry up to four oxygen molecules per hemoglobin molecule, with the addition of oxygen proceeding in a step-wise fashion. For the third step, the value of the equilibrium constant is Keq=5.86 x 10^-4 although the reaction has a (delta Hº) value of -2.9 kj/mol (Remember that the system is not at room temperature). Heme-Fe^2+ -(O2)2 + O2 <----> Heme-Fe^2+ -(O2)3 Keq=5.86 x 10^-4 (a) calculate delta Gº for this process. (b)From the information provided, calculate...
