,Boyle's Law (Balloon=Barotrauma - ANS The pressure a gas is inversely proportional to
the volume of a gas at a constant temperature.
IV drip rates increase, affects ETT cuffs
A
Dalton's Law
"Dalton's Gang" - ANS Law of partial Pressures.
R
Responsible for soft tissue swelling at altitude
Charles' Law
U
"Charging Charles" - ANS At a constant pressure, the volume of gas is directly proportional
to the absolute temperature of a gas.
As you charge O2 tank, the tank gets hot
LA
Gay Lussac's Law - ANS Direct relationship between temperature and pressure.
ex: car tires in cold weather.
Graham's Law
Grey Matter - ANS Law of Gaseous Diffusion
C
Gas exchange at cellular level
Henry's Law
O
Heineken - ANS Solubility of a gas in a liquid
the BENDS
D
Bends Ground transport is preferred - ANS Type 1 Nitrogen related, painful joints mottled
skin, pruritus; "ants are crawling on their Skin"
Cutis Marmorata- Mottled Skin, can look like a sunburn
Type 2 Neurologic s/s hypovolemic Shock
Arterial Gas Embolism - ANS Boyle's Law
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 - ANS POP; Boyle's law
greatest pressure difference <4 ft
inexperienced divers can cause pneumo or mediastinal emphysema
atmosphere - ANS Sea Level = 1 ATM = 760 Torr
33ft = 2 ATM
66ft = 3 ATA
Physiologic Zone - ANS sea level to 10,000 feet
A
Night Vision is decreases at 5000ft MSL
R
Physiologic Deficient Zone
TUC=Time of useful Consciousness - ANS 10K to 50K ft MSL
O2 pressurization is required
Sign of compression loss is cooler temperature and window fogging.
U
Normally 90 Sec TUC at 30000ft
If a rapid decompression occurs TUC is @45 Sec
LA
Pressure Values - ANS Sea level = 760 Torr = 1 ATM
10K = 523 Torr
18K = 380 Torr = 1/2 ATM
Hypemic Hypoxia - ANS -Reduction in oxygen carrying capacity of the blood.
-Anemia, blood loss
C
histotoxic hypoxia - ANS Limits available 02 due to poisoning of the cytochrome oxidase
system
Cyanide, Alcohol, Carbon Monoxide, Nitroglycerin, Sodium Nitroprusside
O
Hypoxic - ANS Decrease partial pressure of oxygen at altitude
Deficiency in Alveolar 02 exchange
D
Cardiovascular/Pnuemo pts are more susceptible
Stagnant Hypoxia - ANS Reduction in blood flow; e.g. positive G maneuvers
Cardiogenic Shock
Stages of Hypoxia (ICDC) - ANS Indifferent: Full reasoning, some loss of night vision
Compensatory: Increased HR Ventilations, Slowed Judgement
