Barotrauma

Question 1

Barotrauma

(concerned with boyle’s law- volumen/pressure relationship of gas)

Answer 1

injury caused by pressure

when ambient pressure is lower than pressure in body pockets/cavities, the body triest to exhaust the pressure to the atmosphere

if it can’t, it can create pain, tissue damage, bleeding..

Question 2

Gastro-intestinal

Answer 2

trapped gasses in the stomach/intestine

causes pressure pain and farts

Question 3

otic barotrauma

Answer 3

when the air in the middle ear is at lower pressure than the cabin - this closes /blocks the eustachian tube

blocked eustachian tube could rupture ear drim

need to pop ear, swallow, do valsalva manoever (esp on descent)

caues pressure pain and reduction in hearing

Question 4

sinus barotrauma

Answer 4

sinuses can be bocked by infection and mucus so can cause pain, headache, bleeding

no protection except to not fly if you have a cold, soar throat, etc..

Question 5

danger of sinus barotrauma

Answer 5

it’s dangerous to climb if you have it.

stop the climb and descend and land.

if you feel it in descend instead…then climb up a bit, then descend slowly and return to previous altitude.

maxillary sinuses will hurt on descend and eyes may water

Question 6

Aerodontalgia

Answer 6

air trapped in cavities of the teeth

you cannot suffer from it during descend because ambient pressure increases and equalizes with the pressure inside the teeth.

sympotoms happen on ascends

Question 7

eustachia tube equalises pressure between

Answer 7

middle east and outer ear (outside environment)

Question 8

what happens to eustachian tube when flying with a cold/flu -** Pressure Vertigo**

Answer 8

especially if one eustachian tube is block and the other isn’t, it can create pressure vertigo and affect the vesitublar canals. Basically there is a lack of pressure balance between the 2 ears

cause diziness and affect balance
