This tool, whether a dedicated device or software application, computes ascent profiles for scuba dives, particularly those exceeding recreational depth limits. It uses mathematical algorithms based on gas absorption and elimination principles to determine safe ascent rates and required decompression stops, preventing decompression sickness. For example, a dive to 40 meters might require a stop at 6 meters for 5 minutes, followed by another at 3 meters for 8 minutes, before surfacing. These calculations consider factors such as dive depth, bottom time, breathing gas mixture, and even previous dives.
Accurate ascent planning is critical for diver safety, making this computational aid indispensable for technical and professional diving. It allows divers to explore deeper environments while mitigating the risks associated with dissolved gases in the body. Historically, divers relied on dive tables, which offer a limited number of pre-calculated scenarios. Modern tools provide personalized calculations, enhancing safety and flexibility in dive planning. This development represents a significant advancement in dive safety, reducing the incidence of decompression sickness.
