Last time we talked about what is decompression sickness (DCS) and how it can affect you or in the worst-case scenario, kill you. This week lets see how we can prevent you from getting DCS.
As a general rule of thumb, don’t take one last dive the same day before leaving for home in a plane with a cabin altitude that is probably around 8000 feet, which is typical with normal airliner. Your bone and muscle will feel the same effect as you were flying outside of the aircraft if you do so.
The recommended time between your dive and flight is at least 12 hours if your dive does not require a controlled ascent stop dive (typical sightseeing dive) and at least 24 hours if your dive requires one.
The reason for waiting is to make sure all the tiny nitrogen bubble trapped in your bone and muscles have enough time to leave your body.
If you feel any bone or muscle pain during a flight after diving the previous day, alert a flight attendant immediately because you might be actually suffering from DCS and you will need medical attention immediately.
So remember the rule of thumb, 12 hours between dive and flight then you should be safe. Have fun and enjoy your dive!
