FP-C – 2026 – Study Guide and Certification Review
Material
Bar otitis media - ANS✔✔ -typically occurs in decent
-pain in the middle ear
Barobariatrauma - ANS✔✔ -caused by large/sudden release of nitrogen from tissues.
-pre-oxygenate prior to flight to blow off excess N2
Baro sinusitis - ANS✔✔ -trapped air in the sinuses
-occurs during ascent
falling atmospheric pressure cannot keep the air in the sinuses compressed, causing the air to
expand and place pressure on the sinus walls
hypoxic hypoxia - ANS✔✔ -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 - ANS✔✔ -the inability of cells to take up or utilize oxygen from the
bloodstream.
stagnant hypoxia - ANS✔✔ -ischemic hypoxia
-reduced brain oxygen is caused by inadequate blood flow to the brain (stroke, shock, heart
attacks, cerebral edema, hydrocephalus)
, hypemic hypoxia - ANS✔✔ reduced brain function caused by inadequate oxygen in the blood
boyles law - ANS✔✔ when a volume of gas increases, pressure decreases; when a volume of gas
decreases, pressure increases.
charles' law - ANS✔✔ as air heats up, volume increases, allowing molecules to spread out
making air less dense.
daltons law - ANS✔✔ 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 - ANS✔✔ rate of diffusion is affected by
-atmospheric pressures, surface area of the membrane, thickness of the membrane.
henrys law - ANS✔✔ as pressure of a gas over a liquid decreases, amount of gas dissolved in
liquid will also decrease.
gas molecules can be dissolved in a liquid and remain in it as long as there is pressure.
gay-lussacs - ANS✔✔ correlation exists between pressure and temperature when volume is
constant. as temperature increases, pressure increases
grahams law - ANS✔✔ the rate at which gas moves through a small hole avoiding interaction
with other particles.
Kehr's sign - ANS✔✔ referred shoulder pain which can indicate splenic injury or ectopic
pregnancy.
