Dive computers work by monitoring the presences of so-called 'silent bubbles using ultrasound.

False - ANSWER-True or False. Divers can limit the adverse effects of long-term exposure to nitrogen by diving Nitrox less than 20 times a year. False - ANSWER-True or False. The most important step divers can take to help avoid oxygen toxicity is to never exceed a PO2 of 2.0. False - ANSWER-True or False. The two gases that a Nitrox diving computer takes into consideration when computing your allowable bottom time are nitrous oxide and carbon monoxide. False - ANSWER-True or False. You ask a Nitrox blender to fill your cylinders with EAN30, but they analyze at 32 percent. You should not be concerned, as this is within the acceptable range of accuracy for Nitrox fills. FO2 - ANSWER-What is the most important setting that must be made to your Nitrox computer before every dive? In which the Fraction of Oxygen (FO2) is 32 percent - ANSWER-The term EAN32 refers to a Nitrox mixture: Indicate you take responsibility for the Nitrox that has been delivered to you, and that you are satisfied that your cylinders have been filled properly. - ANSWER-The primary function of a Nitrox fill station log is to: It is safe to use down to the maximum recommended sport diving depth limit of 40m/ ft and it provides a good combination of safety and extended bottom time - ANSWER- EAN32 is a good choice for Nitrox diving because: Longer bottom times and shorter surface intervals - ANSWER-The primary benefits of using Nitrox include: Nitrogen and Oxygen - ANSWER-The air we normally breathe consists primarily of: Nitrogen, ascend - ANSWER-Decompression sickness usually occurs when you have an excess amount of __________ in your body and you ________ too quickly. No changes are needed, unless required by manufacturer's specifications or local laws/regulations. - ANSWER-What are the changes that must be made to a regulator to prepare it for use with Nitrox mixtures whose FO2 does not exceed 40 percent? Oxygen toxicity - ANSWER-The primary risk associated with Nitrox diving (as opposed to diving air) is: Pain in the joints, Numbness and paralysis, and Loss of balance - ANSWER-The most common symptoms of decompression sickness can include, but are not limited to:

True - ANSWER-True or False. The two most important pieces of information that will appear on a Nitrox fill tag or label are FO2 and MOD. You may discover that it has defaulted to 21 percent, you risk having the computer assume you are using a Nitrox mixture whose FO2 is different from what it actually is, and you may increase your risk of oxygen toxicity and/or decompression sickness. - ANSWER-If you do not set your dive computer's FO2 prior to every dive: You may not be able to make a direct ascent to the surface without substantially increasing your risk of decompression sickness and your dive computer may require you to make a series of decompression stops - ANSWER-What may happen if you go too deep or stay too long?
