Question 1

Inital intervention for managing a patient presenting with bariobariatrauma is

Answer 1

Administer high flow O2 by NRB 15 min prior to lift off

Question 2

What is bariobariatrauma

Answer 2

Overweight perosns are more susceptible to evolved gas decompression sickness as fatty tissue contains more nitrogen

Question 3

What is the Bends

Answer 3

Pain in and around the joints and can become progressively worse during ascent

Question 4

What is The Chokes

Answer 4

Pain in the chest caused by blocking of smaller pulmonary blood vessels by innumerable small bubbles. In severe casaes there is a sensation of suffocation

Question 5

Which gas law is described by inversely proportional relationship between the absolute pressure and volume of a gas if the temp is constant within a closed system ex, air in a ETT cuff expands upon ascent and contracts during descent

Answer 5

Boyles law

Question 6

Which gas law is described by the rates of movement of gasses at the same temp and pressure are inversely proportional to the square root of its molecular mass

Answer 6

Grahms Law

Question 7

Which gas law is described by the total pressure of a gas mixture is the sum of the individual or partial pressure of all the gases in the mixture

Answer 7

Daltons Law

Question 8

Which gas law is described by the law of volumes states that for an ideal gas at constant pressure, the volume is proportional to the absolute temp, which describes how gases tend to expand when heated

Answer 8

Charles Law

Question 9

Which gas law is described by A sample of a gass at a constant volume is directly proportional to its temp, ex if a gas temp decreses, then so does its pressure

Answer 9

Gay-lussac Law

Answer 10

.25 inch

Question 11

Define Sterile cockpit

Answer 11

Prohibits nonessential communications between crew and pilot during critical phases of flight

Question 12

What should be the only thing taken from the aircraft after a crash

Answer 12

survial kit

Question 13

A patient recieving O2 at 2 lpm becomes hypoxic during flight what do you do any why

Answer 13

Turn up O2,
The patient sufferred hypoxic Hypoxia due to the high altitude and low barometric pressure. There is a fdeficiency in the alveolar oxygen exchange which interfers with gas exhange in ventilation and diffusion.

Answer 19

30,000 90sec
35,000 30-60sec
>40,000 <15 sec
