Feeling Uncomfortable or Unwell

There may be various causes for this feeling. You should STOP, BREATHE, THINK, and ACT.

• Signal, if you are able, that something is wrong to your buddy or dive professional, and SLOWLY begin ascent procedures.
• Check the depth and gas supply (submersible pressure gauge, or SPG) while ascending.
• Ensure that you concentrate on buoyancy control during ascent.
• When reaching the surface, concentrate on establishing positive buoyancy.
• Signal to the surface support for assistance.
