Question 13

what is another atmospheric pressure

Answer 13

is also know as barometric pressure

Question 14

what is 1 TORR

Answer 14

it equals 760 mmhg

Question 15

what is Dalton’s Law

Answer 15

the sum of all the partial pressures equal the total pressure.

Question 16

what is Boyle’s Law

Answer 16

when the pressure increases the volume decreases and when the pressure decreases the volume increases.

think of a balloon.

Question 17

what is Charles Law

Answer 17

As the temperature increases so does the volume. As the temperature decreases so does the volume.

think of a tire on a cold day.

Question 18

Gay Lussac’s Law

Answer 18

-As altitude increases, the temp will decrease and so does the volume.
-as altitude decreases, the temp will increase and so does the volume.

Question 19

what is Henry’s Law

Answer 19

Gas dissolved in to a liquid.

decompression sickness

Question 20

what are flight stressors

Answer 20

hypoxia, noise, vibration, fatigue, G-force, barometric pressure, thermal changes, decreased humidity

Question 21

What types of hypoxia are there

Answer 21

-hypoxic hypoxia
-hypemic hypoxia
-histotoxic hypoxia
-stagnant hypoxia

Question 22

what is hypoxic hypoxia

Answer 22

decrease in alveolar O2 exchange.

due to Boyles law, as the elevation increases so does the molecules size. bigger molecules means less molecules per breath.

Question 23

what is hypemic hypoxia

Answer 23

reduction in RBC’s in the blood so it doesn’t carry as much O2

Question 24

what is histotoxic hypoxia

Answer 24

caused by poisoning or metabolic disorder

Question 25

what is stagnant hypoxia

Answer 25

reduction of cardiac output or the pooling of blood

Answer 26

-indifferent stage -compensatory stage -disturbance stage -critical stage

Question 27

indifferent stage of hypoxia

Answer 27

-experienced between sea level and 10,00 ft. - O2 sat of 90-98%

Question 28

Compensatory stage of hypoxia

Answer 28

-experienced between 10,000 ft and 15,000 ft -O2 is at 80-89%

Question 29

Disturbance stage of hypoxia

Answer 29

-experienced between 15,000 ft and 20,000 ft. -O2 sat of 70-79% -cognition impairment most critical

Question 30

critical stage of hypoxia

Answer 30

-experienced above 20,000 ft - O2 sat of 60-69% -mental confusion followed by incapacitation, unconsciousness and death.
