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) ~Barodontalagia (air under tooth) ~Barosinusitis (sinus) ~Barobariatrauma (like the bends) Barotitis Media - type of problem & Tx A descent problem Tx: Easiest way to fix, go back to altitude Valsava maneuver Neosyneprhine or Afrin to vasoconstrict Treat pain symptomatically Barodontalagia- type of problem & Tx An ascent problem Seen with newer dental work Tx: analgesics, slower descent, Boyle's Law Barosinusitis- type of problem & Tx An ascent (more so) but can be decent problem Seen with sinusitis Tx: analgesics, Afrin and slower ascent. Barobariatrauma- type of problem & Tx An ascent problem Seen with morbidly obese patients (more lipid tissue=more nitrogen) Gases in adipose tissue released into plasma causing nitrogen narcosis "
