10.2.3. Altitude diving
The atmospheric pressure is lower at high altitudes than at sea level. After traveling
to a higher altitude, you will have additional nitrogen in your body, compared to the
equilibrium situation at the original altitude. This "additional" nitrogen is released
gradually over time and equilibrium is restored. It is recommended that you acclimatize
to a new altitude by waiting at least three hours before making a dive.
