One of the more frequently used treatment schedules is the US Navy Table 6, which provides hyperbaric oxygen therapy with a maximum pressure equivalent to 60 feet (18 m) of seawater (2.8 bar P O 2) for a total time under pressure of 288 minutes, of which 240 minutes are on oxygen and the balance are air breaks to minimise the possibility of ...
Exertion increases heat production by metabolic processes, but when breathing gas is cold and dense, heat loss due to the increased volume of gas breathed to support these metabolic processes can result in a net loss of heat, even if the heat loss through the skin is minimised.
This model allows a faster rate of decompression at the start of the ascent to utilise the inherent unsaturation due to metabolic use of oxygen, followed by a constant rate limited by oxygen partial pressure of the breathing gas. The period of constant decompression rate is also limited by the allowable maximum oxygen fraction, and when this ...
Gas is breathed at ambient pressure, and some of this gas dissolves into the blood and other fluids. Inert gas continues to be taken up until the gas dissolved in the tissues is in a state of equilibrium with the gas in the lungs (see saturation diving), or the ambient pressure is reduced until the inert gases dissolved in the tissues are at a higher concentration than the equilibrium state ...
As water conducts heat 20 times more than air, and has a much higher thermal capacity, heat transfer from a diver's body to water is faster than to air, and to avoid excessive heat loss leading to hypothermia, thermal insulation in the form of diving suits, or active heating is used.
These range from the toxic effects of oxygen at high partial pressure, [40] through buildup of carbon dioxide due to excessive work of breathing and increased dead space, [41] to the exacerbation of the toxic effects of contaminants in the breathing gas due to the increased concentration at high pressures, [42] and include effects on the ...
Sirumalai is a dense forest region with a moderate climate throughout the year. With an altitude of 1600 metres above sea level, it contains diversified flora and fauna. The hill has 18 hairpin bends. On the 18th bend are a church and a viewpoint of Dindigul city and the Dindigul Rock Fort. The hill contains a small waterfall as well.

Valparai Ghat Road – This road in Coimbatore district begins at Monkey Falls and has 40 hairpin bends. Dhimbam Ghat Road – A 14-kilometre (8.7 mi) road with 27 hairpin bends, located along the Western Ghats and close to the Eastern Ghats.
