Aeromedical exam Questions and answers
Define Hypoxia (PHAK 17-3) - ✅✅anytime tissues in the body are deprived of oxygen, particularly the
brain
What are the 4 types of Hypoxia? (PHAK 17-3) - ✅✅Hypoxic Hypoxia
Hypemic Hypoxia
Stagnant Hypoxia
Histotoxic Hypoxia
Define Hypoxic Hypoxia (PHAK 17-3) - ✅✅Insufficient oxygen to the whole body. Typically
environmental.
Define Hypemic Hypoxia (PHAK 17-3) - ✅✅A person's blood is unable to carry sufficient oxygen.
Usually due to disease, but can be environmental like Carbon Monoxide (CO) poisoning
Define Stagnant Hypoxia (PHAK 17-3) - ✅✅Oxygen rich blood isn't moving around the body. Inflight, it
is usually from G-Forces, but can also be from heart failure or a limb "going to sleep"
Symptoms of Hypoxia (PHAK 17-4) - ✅✅Any all or none:
Cyanosis
Headache
Decreased response to stimuli
Impaired judgement
Euphoria
Visual Impairment
Drowsiness
Lightheadedness
Tingling fingers and toes
Numbeness
, Treatment of Hypoxia Inflight (PHAK 17-4) - ✅✅Reduce altitude or land
Supplemental (tank) oxygen if available
Define Hyperventilation (PHAK 17-4) - ✅✅Excessive rate of depth of respiration leading to abnormal
carbon dioxide loss
Symptoms of Hyperventilation (PHAK 17-4) - ✅✅Some all or none:
Visual Impairment
Unconsciousness
Lightheaded or dizzy sensation
Hot and Cold Sensations
Muscle spasms
How can you tell the difference between Hyperventilation and Hypoxia? (PHAK 17-4) - ✅✅You might
not be able to tell the difference
How do you treat Hyperventilation? (PHAK 17-55) - ✅✅Slow breathing rate
Breath into a pag
If you are unsure to treat for Hyperventilation or Hypoxia, which should you try to treat first? -
✅✅Hypoxia can cause death, so you should treat it first. If the person's symptoms don't change or
worsen, you can switch to treating for Hyperventilation.
Define Histotoxic Hypoxia (PHAK 17-4) - ✅✅Inability of cells to use oxygen or transfer to and from the
blood. Usually caused by chemicals like drugs or poisons. On rare occasions can be cause by disease.
Alcohol causes ________________ hypoxia. (PHAK 17-4) - ✅✅Histotoxic
Altitude causes ______________ hypoxia. (PHAK 17-4) - ✅✅Hypoxic
