Hyperbaric Tech Review,Questions And
Answers.
Boyle's Law (Think of water boiling, P&V inversely related) - answer:-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 - answer:-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) - answer:-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) - answer:-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) - answer:-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 - answer:-Visual changes ( especially tunnel vision )
Ringing in the ears ( tinnitus )
Nausea
, Hyperbaric Tech Review,Questions And
Answers.
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)
What is the ppO2 of Nitrox 40 at 70 fsw? - answer:-
What is the best oxygen percentage to use if your chamber only goes to 90 fsw and you
want to maintain a 3.0 ppO2? I have - answer:-
At what depth would your patient be exposed to 2.0 ppO2 while breathing 75%
Oxygen? - answer:-
What are some symptoms of Nitrogen Narcosis? - answer:-Poor judgement, short-term
memory issues, difficulty concentrating, sense of euphoria, disorientation,
hallucinations, hyper focusing on specific object/area, reduced nerve/muscle function.
What gas laws have to do with absorption of inert gas into the tissues of a diver? -
answer:-The amount of gas absorbed by a diver at depth is directly proportional to the
partial pressure of the gases breathed. As the depth increases, more inert nitrogen is
absorbed into the body and longer decompression is required to release the diffused
nitrogen from the body tissues.
What are the symptoms of DCS type 1? - answer:-Pain (simple pain)
Marbling
Swelling
What are 5 different kinds of type 2 DCI? - answer:-Neurological, Pulmonary,
Unexpressed Bilateral Pain, Cardiac, Inner Ear**
OR
