KFP-C QUESTIONS WITH COMPLETE
SOLUTION
Barotitis media - -typically occurs in decent
-pain in the middle ear
Barobariatrauma - -caused by large/sudden release of nitrogen from tissues.
-pre-oxygenate prior to flight to blow off excess N2
Barosinusitis - -trapped air in the sinuses
-occurs during ascent
falling atmoshperic pressure canot keep the air in the sinuses compressed, causing the air to expand and
place pressure on the sinus walls
hypoxic hypoxia - -inadequate ventilation or reduction in PO2
-the lack of oxygen entering the blood
-reduced atmospheric pressure reduces alveolar PaO2
-symptoms begin above 5000'
histoxic hypoxia - -the inability of cells to take up or utilize oxygen from the bloodstream.
stagnant hypoxia - -ischemic hypoxia
-reduced brain oxygen is caused by inadequate blood flow to the brain (stroke, shock, heart attacks,
cerebral edema, hydrocephalus)
hypemic hypoxia - reduced brain function caused by inadequate oxygen in the blood
boyles law - when a volume of gas increases, pressure decreases; when a volume of gas decreases,
pressure increases.
charles' law - as air heats up, volume increases, allowing molecules to spread out making air less dense.
daltons law - gas molecules are unaffected by each others motion because of the space between the
molecules.
-increasing altitude results in proportional decrease of partial pressures of gases found in atmosphere
ficks law - rate of diffusion is affected by
-atmospheric pressures, surface area of the membrane, thickness of the membrane.
