Questions and Answers

What are the four types of hypoxia?

Hypoxic, Anemic, Stagnant, Histotoxic

What is Hypoxic hypoxia?

  • The blood flow is reduced or unevenly distributed.
  • The tissue cells are poisoned and unable to use oxygen.
  • The amount of functional hemoglobin is too small.
  • The oxygen pressure in the blood going to the tissues is too low. (correct)
  • What is Anemic hypoxia?

  • The blood flow is reduced or unevenly distributed.
  • The oxygen pressure in the blood is too low.
  • The tissue cells are poisoned.
  • The amount of functional hemoglobin is too small. (correct)

    Study Notes

    Types of Hypoxia

    • Four main types of hypoxia: Hypoxemic, Anemic, Stagnant, Histotoxic.

    Hypoxemic Hypoxia

    • Characterized by low oxygen pressure in the blood, leading to insufficient saturation of hemoglobin.
    • Results in inadequate oxygen delivery to tissues.

    Anemic Hypoxia

    • Occurs when there is an insufficient amount of functional hemoglobin in the blood.
    • The decreased hemoglobin capacity limits the blood's ability to transport oxygen effectively.

    Stagnant Hypoxia

    • The blood may be normal in composition, but there is reduced or uneven blood flow to tissues.
    • This form can be caused by various factors that affect circulation, leading to localized oxygen deficiency.

    Histotoxic Hypoxia

    • Involves poisoning of tissue cells, which impairs their ability to utilize oxygen.
    • Can be a result of various diseases affecting blood, heart, circulation, and lungs, leading to cellular dysfunction.
