Hypoxia Defenition
Lack of oxygen within our blood
4 types of Hypoxia & their definition
- Hypmeic- Lack of oxygen in the blood because of carbon monoxide
- Hypoxic- Lack of oxygen molecules in the pressure
- Histotoxic- Drugs and Alcohol prevent oxygen from getting into the bloodstream
- Stagnant-Lack of blood circulation (Gs)
Symptoms & Solution of Hypoxia
-Cyanosis, Imparniess, Drowsy
Solution: Descend or use supplemental oxygen
Hyperventilation (Definition)
Lack of Carbon Dioxide in the Body (rapidly breathing)
Symptoms & Solution of Hyperventilation
-Muscle spams
-Headaches
-Dizziness
-Tingilnig
Solution:
-Get them talking
-Breathe into a bag
What is ICEFLAGS
ICEFLAGS
Inversion- when a pilot quickly transitions from a climb to straight-and-level, fluid can cause you to still believe you are climbing
Coriolis- Fluid in the ear settles from turning too long, if you abruptly move your head you become disoriented
Elevator- Your aircraft gets a quick boost, and your inner ear tells your brain that you’re in a climb. However, you’re not climbing – your altitude hasn’t changed.
False Horizon- Your brain spots something, a cloud bank, a line of lights, or a pattern of stars, and decides, “That’s the horizon!”
Leans- Entered a turn too slowly, fluid in the ear does not react so when you correct it you think you are turning in the wrong direction
Autokinesis- If you fix your gaze on a light for more than a few seconds, it can start to move (brain thinks its moving).
Graveyard Spiral- If you stay in a turn long enough, the fluid in your ears stops moving. As you return to level flight, you feel like you’ve turned in the opposite direction, and you return back to the original turn. the airplane starts descending. Because you think you’re in a wings-level descent, you pull back on the yoke. But what really happens is you tighten the spiraling turn and lose even more altitude.
Somatogravic- The rapid acceleration pushes you back in your seat, giving a sensation similar to pitching up. Your brain, ever so deceptive, interprets this feeling as a climb. You might inadvertently push the nose down to counter this, causing a dangerous descent.
