Aeromedical Factors Flashcards
4 types of Hypoxia
-Hypoxic Hypoxia
-Stagnant Hypoxia
-Hypemic Hypoxia
-Hisotoxic Hypoxia
What is Hypoxic Hypoxia
-Not enough oxygen to the body
-Most common type
What is Stagnant Hypoxia
-The body can’t move blood/oxygen through the body
-Commonly caused by G forces
What is Hypemic Hypoxia
-Blood does not accept oxygen
-Commonly caused by Carbon Monoxide poisoning
What are some symptoms of Hypoxia
-Blue lips/nails
-Dizziness
-Euohpria
-Light headed
What should you do if you suspect someone has hypoxia
-Open window
-Descend
-Give oxygen if possible
What is Carbon Monoxide
-Colorless, Odorless gas
-Byproduct of engine exhaust
What can cause Carbon Monoxide
-Cabin heat
-Faulty exhaust
What should you do if there is Carbon Monoxide detected
-Turn cabin heat off
-Open windows
-Descend
What is hyperventilation
-When you breathe too rapidly (not enough CO2 in body)
How to detect hyperventilation
-Dizziness
-Weakness
-Fainting
How to recover from hyperventilation
-Slow breathing to a steady rate
-Breathe into a bag if necessary
What is Decompression Sickness
Sickness caused by too much nitrogen in the body
Whose most at risk for Decompression Sickness
-Scuba Divers
How long until you can take Scuba Divers flying
Upto 8,000ft MSL
-12hr after on land
-24hr after is decompression stops were made
Symptoms of Decompression Sickness
-Joint pain (the bends)
-Seizures
How does ear pressure work?
Inner ear pressure must be able to balance the outside pressure through the eustachian tube
What do you do if inner ear pressure cannot be balanced?
-Ascend to a higher altitude
-On the way back continuously yawn or use val sava maneuver
When should you do methods to prevent ear pressure issues?
Before discomfort is felt
When should you not fly?
Cold or if sinuses are blocked
