In "EANx", the "x" was originally the x of nitrox, [11] but has come to indicate the percentage of oxygen in the mix and is replaced by a number when the percentage is known; for example, a 40% oxygen mix is called EAN40. The two most popular blends are EAN32 and EAN36, developed by NOAA for scientific diving, and also named Nitrox I and Nitrox ...
Wesco was founded in 1952 by Bud Westgate. In the 1980s and 1990s, the company expanded by acquiring Rengo Oil (15 stores) and Weaver Oil (19 stores). Wesco now owns and operates a bulk fuel and propane business under the name Wesco Energy, along with six Subway locations and six Wesco Deli locations. [2]
Most humans can function at rest with an oxygen level of 15% at one atmosphere pressure; [1] a fuel such as methane is combustable down to 12% oxygen in nitrogen. A small room of 10 meter 3 has 2.08 meter 3 (2080 liters) or 2.99 kg of oxygen which would occupy 2.62 liters if it was liquid. [2]
Michigan: 87 89 93 85 and 86 octane may be sold if labeled as subregular [6] Minnesota: 87 89 91 110 octane fuel may be available at certain locations in southern parts of the state. Mississippi: 87 89 93 Missouri: 87 89 91/93 Some Phillips 66, Break Time, and Conoco stations sell 91 octane premium.
Tidal volume increases by 30–40%, from 0.5 to 0.7 litres, [9] and minute ventilation by 30–40% [9] [10] giving an increase in pulmonary ventilation. This is necessary to meet the increased oxygen requirement of the body, which reaches 50 ml/min, 20 ml of which goes to reproductive tissues. Overall, the net change in maximum breathing ...
Natural air includes 21% oxygen, which is equivalent to F I O 2 of 0.21. Oxygen-enriched air has a higher F I O 2 than 0.21; up to 1.00 which means 100% oxygen. F I O 2 is typically maintained below 0.5 even with mechanical ventilation, to avoid oxygen toxicity, [2] but there are applications when up to 100% is routinely used.
The oxygenation index is a calculation used in intensive care medicine to measure the fraction of inspired oxygen (FiO2) and its usage within the body. A lower oxygenation index is better - this can be inferred by the equation itself. As the oxygenation of a person improves, they will be able to achieve a higher PaO2 at a lower FiO2.
D LCO or T LCO (diffusing capacity or transfer factor of the lung for carbon monoxide (CO), [1]) is the extent to which oxygen passes from the air sacs of the lungs into the blood. Commonly, it refers to the test used to determine this parameter. It was introduced in 1909. [2]
