Cyanosis does not occur in severe anemia because -
Ans. (c) Critical concentration of Hb required to produce Cyanosis is reduced(Ref: Ganongy 25th ed/p.646)Cyanosis is not seen in anemic hypoxia because critical concentration of Hb required to produce cyanosis is reduced
Hypoxia stimulates erythropoietin production
Oxygen carrying capacity of available Hb is increased
Critical concentration of Hb required to produce Cyanosis is reduced
Oxygen hemoglobin curve shift to the right
