Hyperbaric Tech Review Questions and Answers Graded A+
Boyle's Law (Think of water boiling, P&V inversely related) - Answers A law stating that the pressure of a
given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
P1V1=P2V2
Bubbles get bigger as you get closer to the surface
Pressure and volume are inversely proportional
Dalton's Law (Taking a p...*PP) - Law of Partial Pressures - Answers the statement that the total pressure
of a mixture of gases is equal to the sum of the partial pressures of the individual compo 1 nent gases.
Px+Py=P total
Gay-Lussac's Law (P&T directly related - PT going for a run) - Answers law is an ideal gas law which states
that at constant volume, the pressure of an ideal gas is directly proportional to its absolute temperature
(in Kelvin)
P1/T1=P2/T2
Henry's Law (Henry's drinking a beer -Absorption) - Answers Henry's Law has to do with the principles
involving dissolved gas and pressure. It states that the amount of gas dissolved under equilibrium in a
certain volume of liquid is in direct proportion to the pressure of the gas that makes contact with the
liquid's surface
Law of absorption, the body will absorb gases faster at depth. The deeper you go, the body will absorb
gases at a proportional rate.
mDissolved Gas = K * Pgas
, Charles' Law (Charles is watching TV - T&V directly related) - Answers A statement that the volume
occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure
remains constant.
V1/T1=V2/T2uu
Symptoms of CNS O2 toxicology - Answers Visual changes ( especially tunnel vision )
Ringing in the ears ( tinnitus )
Nausea
Twitching ( especially of the face )
Changes in behavior ( irritability, anxiety, confusion )
Dizziness
VENTID-C?
Or
CONVENTID
Stay 60 stay at depth until they are asymptomatic
Wait until symptoms subside - then decrease the depth
Or
Switch to air, wait until symptoms subside (VENTID, not C)
