Suunto VYTEC DS manual PO2, Rgbm, Surf Time

Page 80

O2%	Oxygen percentage or oxygen fraction in
	the breathing gas. Standard air has 21%
	oxygen.
Oxygen partial pressure	Limits the maximum depth to which the
	used Nitrox mixture can safely be used. The
	maximum partial pressure limit for enriched
	air diving is 1.4 bar. The contingency partial
	pressure limit is 1.6 bar. Dives beyond this
	limit have the risk for immediate oxygen
	toxicity.
PO2	Abbreviation for oxygen partial pressure.
RGBM	Abbreviation for Reduced Gradient Bubble
	Model.

Reduced Gradient Bubble Model

Modern algorithm for tracking both dissolved and free gas in divers.

Repetitive dive	Any dive whose decompression time limits
	are affected by residual nitrogen absorbed
	during previous dives.
Residual nitrogen	The amount of excess nitrogen remaining in
	a diver after one or more dives.
SURF TIME	Abbreviation for surface interval time.
Surface interval time	Elapsed time between surfacing from a dive
	and beginning a descent for the subsequent
	repetitive dive.
