Nitrogen Narcosis
What is it?Nitrogen narcosis is an effect on the brain of gaseous nitrogen that occurs to divers who go below 100 FSW, due to the laws of partial pressures. Nitrogen…
Partial Pressure Physics in Diving
Partial-pressure effects: The partial pressure of a gas is determined by the concentration of the gas and the ambient pressure, eg, the concentration of O2 in air is about 21%,…
Oxygen Toxicity
The effects of oxygen are increased at depth so that the maximum PO2 in diving is 1.6 ATA, and this is achieved at 218 fsw breathing air, 132 fsw breathing…
