Dive Terms

The NAUI terms - different than what I learned in NASDS

Note for computer users record only:

  • SIT,
  • Depth,
  • Safety Stop
  • ADT

Acronyms:

  1. (A)MDT - (Adjusted) Maximum Dive Time
  2. ADT - Actual Dive Time
  3. D - Depth
  4. PD/PD+ - Precautionary Depth stop/+ means deep stop. I.e. rule of halves 1.5-3 minutes at half max depth.
  5. RNT - Residual Nitrogen Time.
  6. SAC - Surface Air Consumption
  7. SIT - Surface Interval Time
  8. TNT - Total Nitrogen Time
  9. DCS - Decompression sickness (Bends)

Nitrox Related Terms

  1. EAD - Equivalent Air Depth
  2. MOD - Maximum operating depth solves equation 1 below for Depth, Best Mix would give a depth and solve for .
  3. ATA - Atmospheres absolute (think French) 1 bar = .986923 atm OR 1 bar=1 atm, and 10 M = 1 ATM. ATA = Depth / 33 + 1.

  4. CNS - Central Nervous system oxygen toxicity. Plan , and never let

  5. PT - Pulmonary Toxicity is not a concern for recreational divers.
  6. ConVENTID - Convulsions, Visual, Ears, Nausea, Twitching, Tingling, Dizziness, Dyspenea

Formulas:

  2. Henry's Lay states: That is, the level of in-gassing you will incur is directly proportional to your depth.
