inside the early 20th century, a quantitative model for nitrogen loading and dive tables had been
developed through - ANSJohn Scott Haldane
we say that nitrogen is an inert gas. This means - ANSour bodies do no longer use the nitrogen
we breathe

blessings of diving with nitrox are - ANSlonger dive instances and shorter surface periods
what does the "x" stand for inside the time period EANx? - ANSthe percent of oxygen in the mix
in 1878, Paul Bert set up that_____, liberated as bubbles following surprising decompression
turned into the purpose of decompression sickeness - ANSnitrogen

as a fuel is heated in a rigid closed container its stress will - ANSincrease
"if one amount of fuel will dissolve at one ecosystem of strain, then three portions of gasoline
will dissolve at three atmospheres." this announcement refers to which law? - ANSHenry's Law
atmospheric strain may be measured in lots of methods. What's one ecosystem in millimeters of
mercury? - ANS760 mmHg
the ____ of a specific fuel in a mixture is the part of the full stress exerted by means of that fuel -
ANSpartial strain
what is the absolute strain at 17 msw (fifty six fsw)? - ANS2.7 ata
what's the oxygen partial strain in EAN35 at a intensity of 26 msw (eighty five fsw)? -
ANS1.Three ata
, if the oxygen partial strain for your blend is 1.3 ata at a depth of 37 msw (122 fsw), what's the
fraction of oxygen inside the blend? - ANS0.28
what is the partial stress of oxygen in air at a intensity of 21 msw (69 fsw)? - ANS0.65 ata
the signs of nitrogen narcosis parallel those regularly seen in - ANSalcohol intoxication
____ regulation states: "at a constant temperature, the volume of a gas varies inversely with
absolute strain, while the density of a gasoline varies immediately with absolute stress." -
ANSBoyle's
every 10 meters (33 ft) which you descend within the ocean provides any other surroundings of
pressure to the one surroundings of floor stress - ANStrue
a diver laid low with nitrogen narcosis will always be aware that he is impaired - ANSfalse
the mechanisms of nitrogen narcosis are notion to be just like - ANSanesthesia
the managed launch of strain throughout ascent from a scuba dive is - ANSdecompression
which gas in air is crucial to sustain lifestyles? - ANSoxygen
the number one waste product from the metabolism of oxygen is - ANScarbon dioxide
for most people, signs of hypoxia begin to appear while the PO2 - ANSfalls under about 0.16
ata
pulmonary oxygen toxicity outcomes from - ANSprolonged publicity to increased oxygen partial
pressures
one of the elements that may growth susceptibility to CNS oxygen toxicity is - ANSheavy
exercise and carbon dioxide buildup
the acronym used to don't forget signs and symptoms and signs of oxygen toxicity is -
ANSConVENTID
the encouraged maximum PO2 for enriched air nitrox diving is - ANS1.Four ata
the primary precursor symptom of CNS oxygen toxicity is - ANSprecursor signs and symptoms
are exceptionally variable
a stuporous situation characterized with the aid of impaired intellectual and physical
performance and changes in temper and conduct is referred to as - ANSnitrogen narcosis
