Abstract
Disclosed is a method of providing oxygen rich gas. Oxygen is separated from ambient air with an oxygen separator in discrete pulses, one pulse at a time. The start of the pulse is synchronized with the beginning of an inhalation of a person. The oxygen rich gas in each pulse is separated from the ambient air in real time during a nitrogen adsorption step concurrent with each inhalation.
