| Time Display Mode (post-dive) After making a dive, the Time Display Mode shows additional information (figure 5): a. Nitrogen Bar Graph. The Nitrogen bar graph is a series of nine segments that graphically represent your body's residual nitrogen. During the surface interval, the Nitrogen Bar Graph starts to recede, indicating that you are off-gassing nitrogen. b. Oxygen Bar Graph. The Oxygen Bar Graph is a series of eight segments that graphically represent your CNS clock. It tracks your exposure to higher partial pressures of oxygen when diving Figure 5. with enriched air nitrox. , V... , (post dive) C. Desaturation Time: Desaturation time is the amount of time it takes to release all the residual nitrogen left in your body from previous dives. Any dive made while there is still desaturation time remaining is considered a repetitive dive. |
