Arterial Gas Embolism Boyle's Law

, Flight Paramedic Questions And Answers
breathe holding during ascent on a dive. causes pnuemo. air can be forced into blood stream

creating air bubble blocks.




Hyperbaric Chamber! fly in aircraft under 10k Mean Sea Level




Pulmonary Overpressurization POP; Boyle's law


greatest pressure difference <4 ft

inexperienced divers can cause pneumo or mediastinal emphysema




atmosphere Sea Level = 1 ATM = 760 Torr


33ft = 2 ATM

66ft = 3 ATA




Physiologic Zone sea level to 10,000 feet




Night Vision is decreases at 5000ft MSL




Physiologic Deficient Zone

, Flight Paramedic Questions And Answers
TUC=Time of useful Consciousness 10K to 50K ft MSL


O2 pressurization is required

Sign of compression loss is cooler temperature and window fogging.

Normally 90 Sec TUC at 30000ft

If a rapid decompression occurs TUC is @45 Sec




Pressure Values Sea level = 760 Torr = 1 ATM


10K = 523 Torr

18K = 380 Torr = 1/2 ATM




Hypemic Hypoxia -Reduction in oxygen carrying capacity of the blood.


-Anemia, blood loss




histotoxic hypoxia Limits available 02 due to poisoning of the cytochrome oxidase system


Cyanide, Alcohol, Carbon Monoxide, Nitroglycerin, Sodium Nitroprusside
