Learn - Medical Factors
A condition where there is insufficient oxygen available to the entire body, leading to reduced oxygen supply to tissues. Occurs when the blood cannot carry enough oxygen to the cells, often due to blood loss or carbon monoxide poisoning.
Hypoxic Hypoxia
insufficient oxygen available to the body as a whole
Key Terms
Hypoxic Hypoxia
insufficient oxygen available to the body as a whole
Hypemic Hypoxia
blood is not able to take up and transport a sufficient amount of oxygen to the cells. (blood loss, CO poisoning)
Histotoxic Hypoxia
inability of cells to effectively use oxygen. (drugs or alcohol)
Stagnant Hypoxia
oxygen rich blood isn’t flowing to cells (G forces, shock, limb going to sleep)
Hyperventilation
excessive rate and depth of respiration leading to abnormal loss of carbon dioxide from the blood (fix by slowing breathing, or breathing into bag)...
Dehydration effects
headache, fatigue, cramps, sleepiness, dizziness
