Oxygen equivalent compares the relative amount of oxygen available for respiration at a variable pressure to that available at SATP. As external respiration depends on the exchange of gases due to partial pressures across a semipermeable membrane and normally occurs at SATP, an oxygen equivalent may aid in recognizing and managing variable oxygen availability during procedures such as hyperbaric oxygen therapy or . It does so by expressing oxygen concentration as a ratio of the partial pressure of oxygen at a given altitude or pressure to Standard Atmospheric Pressure; rather than as a ratio of the PO2 at a given pressure to the total pressure of the gas mixture. The latter would generally be 0.2095, the atmospheric concentration by volume of O2, although FO2 and Patm vary for extraterrestrials. Calculations occur as follows: Let O2E be oxygen equivalent, FO2 be the fractional concentration of oxygen, Patm (generally 760 mmHg, barring intergalactic travel), Pb be the barometric pressure, and dP be the change in pressure at a given altitude. Then, O2E = FO2(Pb + dP)/ Patm It is worthwhile to note that pressures may often be expressed in units of distance such as feet when diving. For this, note that descending 33 ft in salt water or 33.9 ft in fresh water results in a change of 1 atm, so distance and pressure are used interchangeably in this context. (Wikipedia).

Learn the basics about the properties of oxygen. Oxygen is a gas, it has no smell, colour, or taste; but without it, we as humans would not be able to inhabit planet Earth. When cooled to a very low temperature, it will form a liquid and a solid which are both pale blue. Oxygen makes up

This is different from the redox we knew from general chemistry. It's not so much about highlighting electron transfer as it is about the number of bonds to oxygen that an atom possesses. An oxidation increases a carbon's bonds to oxygen, a reduction reduces a carbon's bonds to oxygen. Mak
