What is the best method to track your oxygen and nitrogen exposure while diving?

Using a nitrox-programmable dive computer is the best method to track your oxygen and nitrogen exposure while diving because these devices are designed specifically to manage the complexities of diving with enriched air nitrox. A dive computer calculates real-time exposure to both oxygen and nitrogen based on depth, time, and the specific gas mixtures being used. It continuously monitors your ascent rates and can provide alerts when you approach the limits of your no-decompression time and oxygen exposure, ensuring a high degree of safety.

This technology also takes into account factors such as repetitive dives, allowing for accurate tracking that is crucial for preventing oxygen toxicity and nitrogen narcosis. Manual methods, while useful for record-keeping, do not have the same level of dynamic monitoring capability as modern dive computers.
