Pressure groups are used to classify a diver’s nitrogen absorption levels after a dive, helping to calculate how much time must pass before it’s safe to ascend or perform another dive.

These pressure groups are organized into different levels based on depth and time spent at that depth. The longer the dive time and the greater the depth, the higher the pressure group, which indicates a greater amount of absorbed nitrogen. The system provides divers with a simple way to track and manage these levels to ensure safe dive practices.

How Pressure Groups Work

Pressure groups are essentially categories that indicate the amount of nitrogen absorbed by a diver’s body during a dive. After each dive, the diver’s pressure group is identified and noted. This group then determines the necessary surface interval before the diver can safely go back into the water for another dive.

Dive Times and Limits

The relationship between dive depth, time, and pressure groups is governed by a set of established guidelines. By understanding these relationships, divers can calculate the maximum time they can safely stay at a given depth and the necessary decompression intervals required for multiple dives.

Pressure Group	Time at Depth	Surface Interval Required
A	Short time at shallow depths	Minimal surface time required
B	Moderate time at moderate depth	Medium surface time required
C	Long time at deeper depths	Long surface interval required

By accurately tracking pressure groups and understanding the corresponding dive times, divers can reduce the risk of nitrogen narcosis and decompression sickness. This knowledge plays a key role in safe dive planning and allows divers to make informed decisions based on their dive profile.
