Running out of air is the most common trigger for diving accidents. It seems like a no-brainer, but several factors can affect consumption rate. Be air aware: Monitor your air supply.
- Incorporate gas supply into your dive planning. You can only stay under as long as you have enough gas remaining for a safe ascent. Don’t forget to save some gas for flotation. Good rules of thumb for turnaround limits are when you have used:
- Check your gauge regularly.
- Be aware that exertion, like when swimming in strong currents and depth will affect your air consumption.
- Anxiety or stress can also affect air consumption. Try to maintain normal breathing, but if you do feel anxious, keep a closer eye on your gas supplies; it may dwindle more rapidly than usual.
- Running out of air is an easily avoidable mistake that carries serious repercussions.
