CFRN: Flight Physiology (2023/2024) Already Passed What is Boyle's Law? Boyle's Balloon Balloon expands as rises 2/2 less pressure against it. Think of things ABOVE sea-level Closer to sea-level, more barometric pressure. Gas volumes expands as barometric pressure ↓ Temperature is the same What are the common medical problems associated with Boyle's law? ~Arterial gas embolism (needs to be in a pressurized aircraft) ~pneumocephalus 2/2 depressed skull Fx ~Barotitis Media (middle ear) ~Bar...

Barotitis media correct answer: -typically occurs in decent -pain in the middle ear Barobariatrauma correct answer: -caused by large/sudden release of nitrogen from tissues. -pre-oxygenate prior to flight to blow off excess N2 Barosinusitis correct answer: -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 correct answer: -inad...
