CALCULATIONS WITH THE RULE TO DETERMINE THE LIMITS OF O2 TOXICITY
The REGOLO for this kind of calculation has “standard” references of enriched mixture
of oxygen (Nitrox 32% - 36% - 40% and 50%) and these references are recognizable by their
YELLOW color that highlights them from the black or RED color background on a white background. The premise is that the use of this rule is advisable as a possible purpose to check or review the planning already verified in the calculations. Due to the size of the ruler, reduced to include it in the clock, reading errors may occur. This is why it is suggested to use the slide rule only as a secondary control or back-up tool. The numerical values must be considered as absolute pressure values and therefore in BAR as indicated in the outer ring next to the number “60”. These values will have to be converted into meters by subtracting 1 atmosphere. If the resulting number is 35, it means that the value to be read will be 3.5 BAR absolute pressure and from here remove 1 BAR as
earth pressure = 2.5 BAR equivalent to 25 meters
