Precautions for use

Emergency response


■Ascent rate and decompression sickness

To quickly remove carbon dioxide from carbonated drinks, open the tap and expose the carbonated drink to atmospheric pressure.
The same method is used to effectively discharge the nitrogen that has dissolved in the human body. That means the nitrogen that has dissolved in the human body is effectively discharged by ascending to the water surface at the fastest possible ascent rate.
By the way, in carbonated drinks, there is no problem if carbon dioxide gas bubbles, but if nitrogen bubbles in the human body, it will cause decompression sickness.
Therefore, it is effective for discharging nitrogen to ascend at the maximum ascending speed that does not cause decompression sickness.
Currently, most dive computers and STARS dive tables have a maximum ascent speed of 10m per minute.

Carbonated beverages do not have a problem if carbon dioxide gas bubbles

If nitrogen bubbles in the human body, you will have decompression sickness!
