december 1987 question
can someone help me with this q
NORMAL Hb conc is about 15gm./dl bllod n normal arterial oxygen content is about 20ml.oxygen/dl blood.An anemic indiviual breathing room air with a Hb conc of 10gm/dl blood is expected to have
1 normal arterial oxygen tension n normal arterial oxygen content
2 reduced art oxygen tension n normal arterial oxygen content
3 normal art oxygen tension n reduced arterial oxygen content
4 reduced art oxygen tension n reduced arterial oxygen content

2 reduced art oxygen tension n normal arterial oxygen content
3 normal art oxygen tension n reduced arterial oxygen content
4 reduced art oxygen tension n reduced arterial oxygen content

The answer is c
Since the Hb conc is less hence the arterial oxygen content is reduced and their is no effect on the saturation hence its normal art oxygen tension..

dont confuse oxygen tension with the amount of oxygen.
