Normal hemoglobin concentration is about 15 gm./dl. blood and normal arterial oxygen content is about 20 ml. 02/dl. blood. An anemic individual breathing room air with a hemoglobin concentration of 10 gm./dl. blood is expected to have
A) reduced arterial oxygen tension and normal arterial oxygen content.
B) reduced arterial oxygen tension and reduced arterial oxygen content.
C) normal arterial oxygen tension and normal arterial oxygen content.
D) normal arterial oxygen tension and reduced arterial oxygen content.
D)
Oxygen tension means oxygen partial pressure
- when you increase O2 pp, you decrease CO2 pp and vice versa
- partial pressure of O2 will stay the same in anemia, but O2 content will decrease because less Hemoglobin
