Nitrox 32 is NOT used to a depth of 130FSW. This would put your PPO2 at 1.58 ATA, dangerously high. EAN 32 has a maximum opperating depth, or MOD of 111FSW according to recreational diving standards. This puts the PPO2 at 1.4 ATA, the maximum limit for recreational diving. The only time a diver would ever push this 1.4 ATA limit is during an emergency or the decompression phase of a dive where it is acceptable (according to technicial diving standards) to raise this limit to 1.6 ATA to aid in decompression. There are oxygen exposure limits that a diver has to be concerned with when diving nitrox just like you have nitrogen exposure limits (NDL`s) when diving air. These are time limits that become very short when approching the 1.6 ATA level. Over exposure to O2 can cause an Epileptic type seizure called CNS Oxygen Toxicity,not a good thing to have happen when underwater. If you have more questions please ask a professional so you get the correct answers. Dive safe, Scott
