Test 1 CRNA:Nursing Anesthesia - Gas Laws from Valley

QuestionAnswer
A principle for calculating cardiac output from oxygen uptake or carbon dioxide elimination Ficks law of diffusion
The law that states gas pressure is inversely proportional to gas volume at a constant temperature Boyle's Law
The law that states the total pressure of a mixture of gases is equal to the sum of the partial pressures Dalton's Law
6.02 x 10^23 is the Avogadro's law
According to Boyle's law, if the volume of a gas is halved, the pressure is _____. Doubled
Which law explains why a large volume of gas is released from a pressurized cylinder? Ideal gas law
This application describes what Gas law:Squeezing the Ambu bag cause an increase in pressure and decrease in the volume Ideal gas law
This application describes what Gas law:During inspiration when breathing spontanously,intrapulmonary pressure falls and volume increases. Ideal gas law
This application describes what Gas law:During normal expiration, intrapulmonary pressure and volume decreases. Ideal gas law
This application describes what Gas law:Measurement of functional residual capacity (FRC) by body plethysmography Ideal gas law
1 atm = ___ psi 14.7
1 mmHg= ___ cm H20 1.63
1 psi = ___ mmHg 54
According to Law of LaPlace, ___ may be defined as the internal force generated by a structure. tension
According to the Law of LaPlace that formula for cylindrically shaped structures T = PrT = Wall Tension P = Pressure of liquid w/in the cyclinderr = radius
According to the Law of LaPlace, as radius expands, the tension in the wall structure will ___. Increase
According to the Law of LaPlace, as tension in the wall is proportional to the ___. radius
Which law explains: The larger the radius, the higher the wall tensions and the more likely the vessel will rupture. Law of LaPlace
Give 4 places where the law of LaPlace applies a blood vessel, an aortic aneurysm, and the ability of capillary vs. vein to withstand pressure, and the left ventricle.
Which law states that the greater the tension in the ventricular wall at end-diastole, the greater the stroke volume? Frank-Starling law
The law of LaPlace related to ARDS (with no normal surfactant) the smaller alveoli radii will have ______ pressure. higher
The law of LaPlace related to ARDS (with no normal surfactant) the smaller alveoli radii will empty into larger alveoli, causing ___. Atelectasis
What law explains why normal small alveoli do not empty into large alveoli. Law of LaPlace
