EAN 37 Equivalent Air Depth at 12 meters
At 12 meters depth with EAN 37, the Equivalent Air Depth (EAD) is 7.5. This means breathing EAN 37 at 12m feels like diving at 7.5m on air, providing a nitrogen reduction of 4.5 meters.
What is Equivalent Air Depth?
The Equivalent Air Depth (EAD) is the depth at which breathing air would produce the same nitrogen partial pressure as your Nitrox mix at the actual depth. It allows you to use standard air decompression tables while diving with Nitrox.
