How can you build in protection and conservatism into your dive? By using Gradient Factors.

Dr Neal W Pollock

Renowned diving physiologist Dr Neal W Pollock filmed a EUROTEK TEKTalk where he discussed the foundations of decompression physiology, M Values and what Gradient Factors are.

Pollock is the Research Director at Divers Alert Network (DAN) and a Research Associate at the Center for Hyperbaric Medicine and Environmental Physiology, Duke University Medical Center. Both positions are based in Durham, North Carolina.

"Decompression safety is based on a safe amount of supersaturation. It is clear today that you can have both bubbles and decompression sickness at supersaturations below the M Value." Neal W Pollock

Gradient Factors are described as a two-number pairing, with a low number first, followed by a high number. Neal Pollock explains what each number means and how you go about choosing your own personal Gradient Factor settings.
