Does nitrox reduce decompression sickness?
Diving with Nitrox reduces the risk of decompression sickness.
Why do scuba divers have to come up for air slowly?
When divers need to fill their air tanks, they must do so slowly. This is because as the tank fills, all of the air molecules are being jam packed into a rigid area. Those molecules will start bumping into one another as the pressure builds- creating heat.
Why do deep water divers need to dive with special compressed air?
These divers needed to breathe special gas mixtures because they were exposed to very high ambient pressure (more than 50 times atmospheric pressure). These suits are capable of withstanding the pressure at great depth permitting the diver to remain at normal atmospheric pressure.
Why do divers need nitrox?
Divers who use nitrox absorb less nitrogen, making them stay underwater for longer. They’re also less likely to get decompression sickness. It’s worth noting that older divers and those who’ve experienced decompression sickness or physical injuries can reduce no-decompression limits with the gas.
Why do divers use nitrox?
Underwater diving Enriched Air Nitrox, nitrox with an oxygen content above 21\%, is mainly used in scuba diving to reduce the proportion of nitrogen in the breathing gas mixture. The main benefit is reduced decompression risk.
Why do scuba divers need to exhale air when they ascend to the surface of the water?
As the diver ascends, the pressure decreases. According to Boyle’s Law, this causes an increase in the volume of the lungs. The diver needs to exhale to adjust for the change in volume caused by the change in pressure.
Why do divers use pressurized air?
Diving with a cold or allergy flare that swells the tubes and prevents clearing is ill-advised. Controlled by the regulator, compressed air fills the lungs according to ambient pressure, allowing more oxygen in a breath as the lungs compress. It’s vital to release compressed air while ascending to prevent lung damage.
Should I dive Nitrox or air?
Breathing air which is enriched with more oxygen reduces the amount of nitrogen and therefore reduces the risk. A dive on Nitrox will be much safer than the same dive profile on air. Deep for Longer: Other than health & safety benefits, Nitrox scuba dives enable you to stay at depth for longer than air does.
What is the advantage of Nitrox?
Recreational Nitrox which may contain anything between 21 and 40 percent of oxygen, has a lower percentage of nitrogen than air. This allows divers to extend their no-decompression limits/ dive time by reducing the amount of nitrogen that is absorbed.
