Fluoroscopy- Chapter 25 question with 100% correct answers rated A+ 2023Minification Gain - correct answer the degree to which the image is minified ( made small) from input phosphor to output phosphor Flux Gain - correct answer involves using an image intensifier to create a brighter image by taking a few x-ray photons and converting that energy into many light photons Flux gain is expressed as the ratio of the number of ____ - correct answer light photons at the output phosphor to the...

dalton's law -:- Pair = Po2 + Pn2 + Pco2 + Par henry's law -:- C = alphaP the concentration/amount of a dissolved gas is a function of the gas's Pp and solubility coefficient partial pressure calculation -:- Pgas = Fgas * Patm inspired partial pressure -:- Pi,o2 = Fo2 * (Patm - Ph2o) air conditioning during inhalation: adds warmth and moisture to the gas --> water gets evaporated in the mucosa, generating a water pressure which decreases the atmospheric pressure at 37C,...
