Air Methods Critical Care Review | Flight
Physiology
A affected person has been receiving IV Nitroprusside for several days. This medication can
purpose buildup of _____________ and purpose what sort of hypoxia after prolonged use? -
ANS-Cyanide, histotoxic hypoxia
An oxygen tank that changed into saved out of doors in very bloodless weather has been
moved interior to a much warmer ambient temperature. One should count on to see:
Decrease in indicated pressure
Increase in indicated strain
Frozen tank valve
The tank eliminated from carrier - ANS-Increase in indicated stress
Gay-Lussac's Law explains the effect of absolute temperature adjustments on fuel in a hard
and fast field with strain increasing with rising temperature, and reducing with falling
temperature. In this case, one may want to assume to see an boom in pressure. This might
no longer purpose freezing of the tank valve, nor might this be some thing that might require
removing the tank from provider.
Anemia and carbon monoxide poisining will reason what form of hypoxia? - ANS-Hypemic
hypoxia
During affected person transports, most pressure-associated modifications will occur: -
ANS-Below five,000 ft
Between zero - 5000 toes
During the morning shift brief, the pilot said that the modern blended team weight and
increased density altitutde due to hight temperatures, the most patient weight from the
helipad is best a hundred and fifty pounds.
This is known to be steady with what law?
Charles'
Dalton's
Boyle's
Graham's - ANS-Charles' Law
Charles' Law explains that as air temperature increases, the air mass will increase in volume
due to the fact the molecules are spaced farter apart, developing an environment in which
wings, rotors, and propellers have much less molecules to work with, making them less
efficient. Dalton's regulation explains gasoline combos. Boyle's Law explains atmospheric
strain. Graham's regulation explains effect or molecular weight diffusion and effusion
For each one thousand-foot growth in altitude, temperature generally decreases with the aid
of what number of degrees? - ANS-2 tiers celsius
Histotoxic hypoxia is the end result of all besides:
Cyanide poisoning
, Prolonged nitroprusside use
Oxygen displacement from toxic fuel
ETOH - ANS-Oxygen displacement from toxic gas
Cyanide poisoning, alcohol intoxication, and prolonged nitroprusside infusions that convert
cyanide block oxygen at tissue degree. Oxygen displacement from toxic gas outcomes in
reduced O2 availability within the environment, which results in hypoxic hypoxia, not
histotoxic hypoxia
Hypoxic hypoxia is the end result of:
Decreased O2 availability
Overuse of O2
Low hbg counts
damaged hbg - ANS-Decreased O2 availability
Hypoxic hypoxia is the end result of decreased oxygen availability due to a decr4ease in
environmental oxygen or boundaries at the pulmonary level. Low hbg outcomes in hypemic
hypoxia. Overuse of oxygen has no have an effect on on availability. Damaged hemoglobin
results in hypemic hypoxia
Night vision starts to lower at how many feet? - ANS-5,000 toes
Stagnant hypoxia takes place with:
Increased blood glide
Third-spacing
decreased blood drift
reduced oxygen availability - ANS-Decreased blood go with the flow
The formula (FiO2 x P1)/P2 is used to calculate FiO2 changes when converting altitudes.
This is a demonstration of which gas law?
Boyle's
Charles'
Dalton's
Henry's - ANS-Dalton's Law
Dalton's Law states that the whole strain exerted is equal to the sum of the partial strain of
the character gasses. Boyl'es regulation explains atmospheric strain. Charles' Law explains
the relationship among quantity and absolute temperature at a consistent stress. Henry's
Law explains gasoline dissolving right into a liquid below strain
This technique is used to mitigate reduced night imaginative and prescient at altitude -
ANS-Off-center viewing
Yoou are transporting a patient diagnosed with ischemic bowel with trapped peritoneal
gasoline. Upon accomplishing cruise altitude, the patient starts offevolved experiencing
excruciating belly pain due to fuel enlargement. This phenomenon can be excellent defined
via what law? - ANS-Boyle's Law
Boyle's regulation explains the effect of changing atmospheric stress on fuel within a flexible
container. Charles' regulation explains the connection among quantity and absolute
temperature at consistent stress. Henry's Law explains the relationship between fuel
dissolving into liquids and the pressure above the liquid. Graham's regulation explains
impact of molecular weight diffusion and effusion
