What should divers do before venturing on a dive using Nitrox?

Before embarking on a dive using Nitrox, analyzing the cylinder contents is crucial for several reasons. Nitrox blends generally have higher concentrations of oxygen compared to air, and knowing the exact mixture is vital for safe diving. Each cylinder must be analyzed to ensure that the mix is appropriate for the planned dive depth and duration, as exceeding the maximum operating depth for a specific Nitrox blend can lead to oxygen toxicity, which can have serious consequences such as convulsions underwater.

It's important to have the precise information regarding the oxygen percentage in the cylinder to accurately plan the dive and manage decompression schedules effectively. Additionally, divers need to familiarize themselves with the associated no-decompression limits based on the specific Nitrox blend they intend to use for the dive. By analyzing the cylinder before diving, divers can help ensure their safety and enhance their overall diving experience.
