2. WOB (WORK OF BREATHING)
Similar to the END Alarm, air diving is used as the scale and method of measuring equivalency. The
addition of helium in trimix gas makes it less dense than air. Therefore it takes less work to inhale and
exhale trimix compared to air at the same depth. The WOB alarm allows the diver to select a depth
that breathing air would be comfortable for them. Then the DSX takes the selected air depth and will
trigger a WOB Alarm when the gas in use reaches the equivalent gas density.
NOTE: The Work Of Breathing stands for the limit set and not the current (actual) depth.
Instead it measures the equivalent depth of diving with air in terms of work of breathing.

1. END (EQUIVALENT NARCOTIC DEPTH)
Air diving is used as the scale and method of measuring equivalency. The diver chooses a narcotic
threshold depth for an air dive. Using this measure, the diver applies this narcotic threshold to any
other breathing gas resulting in a different depth but with equal narcotic levels as their limits.
NOTE: Equivalent Narcotic Depth stands for the limit set and not the current (actual) depth.
Instead it measures the equivalent depth of diving with air in terms of narcosis levels.
