As the first cylinder reaches near pure oxygen (there are small amounts of argon, CO 2, water vapour, radon, and other minor atmospheric components) in the first half-cycle, a valve opens and the oxygen-enriched gas flows to the pressure-equalizing reservoir, which connects to the patient's oxygen hose. At the end of the first half of the cycle ...
A humidifier is a household appliance or device designed to increase the moisture level in the air within a room or an enclosed space. It achieves this by emitting ...
Low-volume humidifiers such as cigar humidors can use distilled water to avoid mineral deposits. [5] Certain biological applications require controlled impurities, especially in experiments. For example, distilling water to be added to an aquarium would remove known and unknown non-volatile contaminants. Living things require specific minerals ...
Many people only require slight increases in inhaled oxygen, rather than pure or near-pure oxygen. [67] These requirements can be met through a number of devices dependent on situation, flow requirements, and personal preference. A nasal cannula (NC) is a thin tube with two small nozzles inserted into a person's nostrils. It can provide oxygen ...

To calculate the total enrichment in a countercurrent centrifuge of height H, one has to add a factor of H/(R√2) in the exponent. According to Glaser, [ 3 ] early centrifuges had rotor diameters of 7.4 to 15 cm and lengths of 0.3 to 3.2 m, and the peripheral speed was 350 to 500 m/s.
