Question
Chapter 48.4, Problem 1R
Summary Introduction
To review:
The significance of fully saturation of hemoglobin with oxygen at 100 mmHg partial pressure of oxygen (PO2) and return to heart in the venous blood at 40 mmHg PO2, reflecting 75% of saturation.
Introduction:
The partial pressure of the gas is defined as the part of the volume occupied by that particular gas in the mixture of the gases. In the atmosphere, the oxygen occupies 21% of the total gases present in the atmosphere. The PO2 at the sea level is nearly 159 mmHg. The hemoglobin is a protein that functions as the carrier of the oxygen in the body.

- A patient carrying a mutant form of hemoglobin (KD = 48 torr) is planning to take part in a hiking trip that involves strenuous physical activity at ~10,000 feet above sea level. The mutant hemoglobin has reduced oxygen binding cooperativity (n = 2.2) and displays no major structural abnormalities. a. Calculate the percent saturation of hemoglobin in the lungs (pO2 = 70 torr at this elevation) for this patient and for an individual carrying a normal version of hemoglobin b. Calculate the percent saturation of hemoglobin in active skeletal muscle tissue (pO2 = 15 torr) for this patient and for an individual carrying a normal version of hemoglobin c. Will this patient transport oxygen from the lungs to active muscle tissues more or less efficientlythan an individual with a normal version of hemoglobin on this trip?
