Inherent stressors (8)
Thermal changes decreased humidity gravitational forces fatigue decreased partial pressure of oxygen barometric pressure change noise vibration
Gx direction of force
Anterior/Posterior
Best tolerated G force
Gx
Gx force example
accelerating in car
Gz direction of force
Vertical
Gz example
falling from a roof, landing on feet
Gy direction of force
lateral
least tolerated G force
Gy
Gy example
t-boned
G forces can be
positive (+) or negative (-) (dragster taking off vs. deploying parachute)
G forces cause BP to
drop
People most affected by high G forces
BP medications (especially B blockers) dehydrated
A cold, dry, high altitude environment has the greatest negative outcome to your patient. Every 1,000 ft increase in elevation causes temps to drop
2 degrees C
Temperature is inversely proportional to
altitude
except for thermal inversion
Barondontalgia affects the
teeth
barondontalgia occurs on
ascent
In barondontalgia, air trapped in fillings expands due to
Boyle’s law
Barondontalgia is also referred to as
Aerodontalgia
Barotitis affects the
ears
Barotitis occurs on
descent
In Barotitis, air trapped in the middle ear can’t vent through the blocked
Eustachian tube
Barotitis is also referred to as
Ear Block
Barosinusitis affects the
sinuses
Barosinusitis occurs on
both ascent and descent
Barosinusitis can also cause
maxillary teeth pain (not same as barodontalgia - which is ascent only)
Barosinusitis is also referred to as
sinus block
