Estimating air consumption is a fundamental aspect of planning a decompression dive. This involves calculating how much air you will need throughout the dive based on factors such as the dive depth, duration, individual breathing rates, and the number of divers in the water. Proper air management is crucial as it ensures that divers have adequate breathing gas for both the descent and ascent stages, including the necessary decompression stops.

Effective planning requires anticipating air needs to prevent running low on air before the dive is completed safely. This consideration not only enhances diver safety by reducing the risk of hypoxia (lack of oxygen) but also allows for more effective descent and ascent management. Planning should also take into account contingencies for potential emergencies that could require additional air.

Other choices present risks or are contrary to safe diving practices. It's vital for divers to use current and accurate charts for depth and no-decompression limits, perform thorough equipment checks before dives to ensure functionality, and adhere to predetermined dive profiles to avoid unnecessary risks associated with improvisation. These practices are established to promote safety and reduce the likelihood of accidents and incidents during dives.
