A diagnosis must be made on circumstantial evidence of atypical behavior, taking into consideration the depth of the dive and the rate of compression. Nitrogen narcosis may be differentiated from toxicity of oxygen, carbon monoxide, or.
Industrial deep-sea divers must breathe a mixture of helium and oxygen to prevent a disorienting condition known as nitrogen narcosis. If a diver's tank is filled with a helium-oxygen mixture to a pressure of 170 atmospheres and the partial pressure of helium is 110 atmospheres, the partial pressure of the oxygen is ? - is the question The answer is 60. Total pressure minus the partial pressure= 170-110= 60.
Scuba diver's diseases include decompression sickness, pulmonary embolus or emboli, oxygen toxicity, nitrogen narcosis, and other afflictions associated with scuba diving, working under different pressures, at sea, or underwater.
there are several reasons. One is the effects of nitrogen narcosis, which is when you go below 100 feet in the water, you get the effects of laughing gas. the other is caused by oxygen toxicity, which is when you are breathing pure oxygen deeper than 130 feet. These are all caused by Boyle's law, I think.
The simple answer is the partial pressure of nitrogen being breathed. The deeper a diver goes, the greater the partial pressure of nitrogen in the air being breathed due to the increased pressure from being deeper. There is also a debate as to whether oxygen contributes to narcosis. But for a more indepth answer ... I don't think anyone really knows why it happens and last I knew there were different theories out there. Perhaps some medical people can jump in here some.
The concentration of helium is increased in some gas mixtures to reduce the partial pressure of oxygen because helium is a low-density gas that is less soluble in the blood than nitrogen. By replacing nitrogen with helium, the overall density of the gas mixture is reduced, which helps to decrease the work of breathing. This is particularly beneficial in diving situations, where high pressures can increase the risk of nitrogen narcosis and oxygen toxicity.
Pulmonary Oxygen Toxicity (PO) and Central Nervous System Toxicity (CNS)
Because nitrogen will block oxygen and prevent combustion.
As breathing gas for diving: A mixture of oxygen and helium (some times containing nitrogen or a small percentage of oxygen) is used to avoid the phenomenon of narcosis when only pure oxygen is used; also helium make the effort for breathing easier.
Abnormally slow breathing is a symptom of oxygen toxicity
It varies. Divers use different breathing gases depending upon their needs.For standard air, it is 21% oxygen and 79% nitrogen.For nitrox, it can be any higher mix of oxygen, but typically either 32% or 36% oxygen, and the balance nitrogen.For trimix, you can have almost any combination of oxygen, nitrogen and helium to suit your depth, and manage your risk to oxygen toxicity and nitrogen narcosis.
Carbon dioxide narcosis happens when people have too much oxygen. It builds up in the body and becomes toxic
