Free Online O2 Table Generator for Freediving

Structure Your Static Apnea Training with Oxygen Tables

O2 tables are used in freediving to organize breath-hold exercises with defined apnea and recovery intervals.

Unlike traditional CO2 tables, O2 tables generally maintain fixed recovery periods while progressively increasing breath-hold durations. These exercises can create significant hypoxic stress and require conservative planning.

How to Use the O2 Table Timer

Choose breath-hold durations appropriate for your experience.
Configure the rounds and recovery intervals.
Use the timer to follow each stage of your dry training session.

Safety: O2 training carries a risk of loss of consciousness. Avoid maximum breath-holds and hyperventilation, and never train in water without qualified safety supervision.
