During ascent does gas expand or contact? - ANS Expand - Boyles Law During descent does gas contract or expand? - ANS Contact - Boyles Law Climb 100m will cause temperature to? - ANS Drop 1-degree Celsius - Charles' law For every 1,000 ft temperature will drop? - ANS 2 degrees Celsius - Charles's law how to calculate celsius to fahrenheit - ANS (°C x 1.8) + 32 = °F How to convert Fahrenheit to Celsius - ANS (°F - 32) / 1.8 = °C the temperature outside is 18 °C. What would that equal in Fahrenheit - ANS (18 * 1.8) + 32 (32.4) + 32= 64.4 °F You're feeling ill and your body temperature is 101.3 °F. What is the temperature in Celsius? - ANS (101.3 - 32) / 1.8 (69.3) / 1.8= 38.5 °C When you charge an oxygen tank, and the tank gets hot; that is an example of what gas law - ANS Charles' Law Does gas volume expand or shrink as temperature increases? - ANS expands Will a volume of a gas shrink or expand when temperature decreases? - ANS Shrink An oxygen cylinder left outside overnight will have a lower pressure reading in the morning due temperature drop. That is an example of what gas law? - ANS Gay-Lussac's Law All carbonated beverages are example of which gas law? - ANS Henry's Law Which gas law can cause the bends or decompression sickness? - ANS Henry's Law Gases diffuse from a higher concentration to an area of lower concentration is which gas law? - ANS Graham's Law This gas law is an example of the ongoing process of the diffusion of oxygen and carbon dioxide in the blood and the transfer of oxygen from blood into the cells. Which gas law is this? - ANS Graham's Law gas bubbles coming out of exposed grey matter when at altitude is an example of which gas law? - ANS Graham's Law Which gas explains why you get hypoxic when you increase in altitude? - ANS Dalton's Law Dalton's Law can be remembered by the phrase "Daltons Gang" because? - ANS Oxygen molecules that were "ganged up" at lower altitudes spread apart at higher altitudes, making less oxygen available for breathing. Ballon, barotrauma, equipment issues, air filled medical device expansion, AGE, and pneumocephalus = which gas law? - ANS Boyle's Soft tissues swelling at altitude "________ Gang" which gas law? - ANS Dalton's Charging Charles - ANS Charles' law Grey Matter = Which gas law? - ANS Graham's Heineken decompression sickness, the bends = which gas law? - ANS Henry's Barotitis media - ANS ear pain or ear block results from failure of the middle ear space to ventilate when going from low to high atmospheric pressure (descent.) Treat with Valsalva maneuver or with Oxymetazoline (Afin) Barodontalgia - ANS Acute toothache caused by air being trapped in a tooth. Commonly occurs during ascent, with decent bringing relief. "baro" means pressure, and "odontalgia" means tooth pain Barosinusitis, or sinus barotrauma - ANS Sinus block sinus block is an acute or chronic inflammation of one or more of the paranasal sinuses produced by the development of a pressure differences, usually negative (ascent) but can occur on BOTH ascent and descent, between the air in the sinus cavity and that of the surrounding atmosphere. Formula for calculating the partial pressure of O2 - ANS Gas concentration X FiO2= PP Dalton's law demonstrates that the concentration of O2 at 43,000 feet MSL is 21%. If the barometric pressure at 43,000 feet MSL is 162 torr, what would the partial pressure of oxygen be at this altitude? A) 45 torr B) 22 torr C) 34 torr D) 14 torr - ANS C) 34 torr Dalton's law states that as we ascend in altitude, the concentration of oxygen remains the same. However, because of the decreased barometric pressure, the partial pressure of oxygen decreases as altitude increases.
