Aeromedical Factors

Question 1

Name and describe hypoxia in the lungs

Answer 1

Hypoxic hypoxia. any condition that interrupts the flow of oxygen into your lungs. this is a kind of hypoxia that you can encounter at high altitudes due to reduced partial pressure of oxygen

Question 2

Name and describe hypoxia in the blood

Answer 2

Hypemic hypoxia this is a condition that interferes with the with the blood’s ability to carry oxygen. anemia and carbon monoxide poisoning are 2 examples of keeping oxygen from attaching to the hemoglobin in the red blood cell.

Question 3

Name and describe the kind of hypoxia that deals with blood circulation

Answer 3

Stagnant hypoxia any condition that interferes with the regular circulation of blood going to the cells some examples are heart failure shock and g force in certain directions

Question 4

Name and Describe the type of hypoxia where the problem is in the cells

Answer 4

Histo toxic hypoxia this is any condition that interferes with the normal utilization of oxygen in the cell This is whenever the cells are not using the oxygen as they normally would for metabilism. some examples of things that can cause this are alcohol narcotics and cyanide

Question 5

What 4 systems in the body can have problems that cause hypoxia?

Answer 5

Lungs blood blood flow and cells

Question 6

What are the 4 kinds of hypoxia?

Answer 6

Hypoxic, Hypemic, stagnant, and hystotoxic

Question 7

What is the difference between signs of hypoxia and symptoms of hypoxia?

Answer 7

Signs can be Detected by an outside observer. symptoms Are noticeable by the person who is hypoxic.

Question 8

What are some signs of hypoxia

Answer 8

Rapid breathing cyanosis (bluing effect of the skin) poor coordination letharge executing poor judgment

Question 9

What are some symptoms of hypoxia

Answer 9

Air hunger fatigue nausea headache dizziness hot And cold flash Visual impairment tingling euphoria

Question 10

What are some indications that somebody you’re observing is hypoxic

Answer 10

Rapid breathing cyanosis (that’s a blueing effect of the skin, Cyan is blue) Poor coordination lethargy executing poor judgments

Question 11

What are some possible indications that you yourself are hypoxic

Answer 11

Air hunger, fatigue, nausea, Headache, dizziness, high and cold Flashes, tingling, visual impairment, Euphoria.

Question 12

What is TUC and EPT

Answer 12

Time of useful consciousness and effective performance time are 2 interchangeable and broad terms describing the time hypoxia limit

Question 13

What are some factors that would increase the substability to hypoxia

Answer 13

Faster rate of assent, physical activity, fatigue, poor nutrition, alcohol, over-the-counter medication.

Question 14

Why does poor nutrition increase your susceptibility to hypoxia?

Answer 14

The brain feeds from glucose exclusively (blood sugar) so if you have low glucose you will be more prone to hypoxia.

Question 15

How can over-the-counter medication increase one’s susceptibility to hypoxia?

Answer 15

Some drugs can reduce your cell’s ability to utilize oxygen properly making you less altitude resistant.

Question 16

What can be done to treat hypoxia?

Answer 16

Administer pure oxygen and slow your breathing rate so as not to cause hyperventilation.

Question 17

How fast is a normal breathing c ycle in a healthy adult ?

Answer 17

12 to 16 breaths every minute

Question 18

Define hyperventilation

Answer 18

Hyperventilation is the state you are in any time you’re breathing faster than normal.

Question 19

Which gas controls your breathing rate?

Answer 19

Carbon dioxide

Question 20

Name some signs and symptoms of hyperventilation

Answer 20

Dizziness, blurry vision, tingling, Twitching muscles, and tetany (Muscle spasm)

Question 21

What are some similarities of hypoxia and hyperventilation?

Answer 21

Dizziness , reduced vision , tingling , rapid breathing.

Question 22

Why does hyperventilation make your vision blurry

Answer 22

As you hyperventilate, Blood is slowly restricted to your brain, affecting your eyes

Question 23

Why does hyperventilation cause tingling?

Answer 23

The alkaline high blood That is present with hyperventilation reacts with the sensitive nerves of the extremities, causing the tingling sensation that is experienced

Question 24

Why does hyperventilation cause twitching muscles?

Answer 24

As The alkaline high blood (caused by hyperventilation) enters the muscle, the muscle will react by twitching. The face and forearm muscles are generally the most prone.

Question 25

How do you treat hyperventilation?

Answer 25

Slow the depths and rates of breathing this takes a conscious effort. If you are not certain whether it is hyperventilation or hypoxia, treat both of them. don the mask and slow down your breathing.
