Deep Diving - Dealing With Depth

Dealing With Depth

• Divers carry larger volumes of breathing gas to compensate for the increased gas consumption and decompression stops.
• Rebreathers manage gas much more efficiently than open circuit scuba, but are inherently more complex than open circuit scuba.
• Use of helium-based breathing gases such as trimix reduces nitrogen narcosis and stays below the limits of oxygen toxicity.
• A diving shot, a decompression trapeze or a decompression buoy can help divers return to their surface safety cover at the end of a dive.
