Flight Physiology and CAMTS

Question 1

Bariobariatrauma is what?

What is the treatment?

Answer 1

Mostly associated with obese pt
Fat holds nitrogen/nitrogen narcosis will ensure during ascent
Acts like decompression sickness

Treatment- high flow O2= diffuse nitrogen

Question 2

Barotitis Media

Answer 2

Head discomfort- Descent!!
Damage to ear from pressure change

Question 3

Barodontalgia

Answer 3

Associated with Ascent
Inflamed pulp/gum abscess/ filling

Question 4

Barosinusitis

Answer 4

Associated with Ascent
disease of sinonasal injury and inflammation due to rapid, uncompensated changes of pressure within the sinonasal anatomy.

Question 5

Bends (DCS)

Answer 5

Pain in and around joints
Can become worst during ascent

Question 6

Chokes (DCS)

Answer 6

pain in chest caused by blocking of smaller pulmonary blood vessels by innumerable small bubbles

Question 7

Paresthesia or creeps (DCS)

Answer 7

symptoms of tingling, itching, and cold & warm sensations

Question 8

Calculate FiO2 in new altitude

Answer 8

(%FiO2 x P1)/ P2

P1 is current barometric pressure
P2 is New barometric pressure at altitude

Question 9

Uniform should fit to allow (_____) of air space between the suit and undergarments

Answer 9

0.25in / 1/4 inch

Question 10

Hypoxic Hypoxia

Answer 10

Referred to as altitude hypoxia

exposure to low barometric pressure results in deficiency in alveolar oxygen exchange

Question 11

Histotoxic Hypoxia

Answer 11

Inability of cells to take up or utilize oxygen from the bloodstream, despite physiologically normal delivery of oxygen

result from tissue poisoning= alcohol, narcotics, cyanide

Question 12

Hypemic Hypoxia

Answer 12

Arterial oxygen pressure is normal, total oxygen content of the blood is reduced

Think Anemia or blood lost

Question 13

Stagnant Hypoxia

Answer 13

Reduced cardiac output, pooling of the blood within certain regions of the body, decreased blood flow to tissues or restriction of blood

Question 14

Airband Frequencies used for internationally designated distress signals

Answer 14

121.5 MHz and 243.0 MHz

Question 15

Altitude vs Average time of useful consciousness (non-pressurized aircraft)

Answer 15

18,000 and lower =30 mins
25,000= 2-5 mins
30,000= 90 secs
35,000= 30-60 sec
40,000 and higher= 15 secs or less

Question 16

Night vision loss occurs at what feet?

Answer 16

At 5,000 ft

Question 17

Contact times should not exceed per CAMTS

Answer 17

15 minutes while in flight (unless continuous tracking)
30 mins for ground units
45 minutes on ground operations

Question 18

Flicker Vertigo

Answer 18

lights that flicker at a rate of 4-20 cycles per second

can cause nausea, vomiting/ seizures and unconsciousness

Question 19

what is HELP?

(Think crash in water)

Answer 19

Heat escape-lessening posture

done by bringing the knees up to the chest and putting the arms across the chest

Question 20

Elements needed to prove malpractice

Answer 20

causation, injury, and damages

Question 21

Breach of Duty can occur in two ways

Answer 21

result of malfeasance (act of commission)
administering the wrong medication
result of nonfeasance (act of omission)
failure to follow a procedure

Question 22

VHF low-band FM (30-50MHz)

Answer 22

signal in this band follows curvature of the earth and has greatest range

Question 23

VHF high-band FM (148-174MHz)

Answer 23

Follows a straight line

Question 24

UHF (403-941 MHz)

Answer 24

limited range and are most often used between ground units and base stations. Used for air to ground and vis versa for short distance

Question 25

800 MHz

Answer 25

digital communication controlled by computers and allows multiple agencies to communicate with each other (less noise, higher frequency, and greater penetration outside of buildings

Question 26

ELT activate by from how many gs?

Answer 26

4Gs

Question 27

Radio Repeater

Answer 27

Radio receiver and radio transmitter

Question 28

Simple

radio type

Answer 28

Ability to transmit on one direction at a time using one single frequency

Question 29

Full duplex

radio type

Answer 29

ability to transmit and receive simultaneously by using two frequencies

normally UHF

Question 30

Half duplex
radio type

Answer 30

Ability to transmit or receive in one direction at a time by using two frequencies

Question 31

Multiplex

radio type

Answer 31

ability to transmit from two or more sources over the same frequency
