What are the five common oxygen systems?

The correct answer outlines five common oxygen systems utilized in aerospace physiology and aviation. Understanding these systems is crucial for effective operation at high altitudes where the availability of oxygen decreases significantly.

Low Pressure oxygen systems are often used in environments where cabin pressurization is not possible, allowing pilots and crew to conduct operations safely at high altitudes. High Pressure systems, on the other hand, involve compressed gas stored under high pressure which is then used to supply oxygen as needed during flight.

Liquid Oxygen systems are efficient for storing large amounts of oxygen in a compact form. They work by converting oxygen into a liquid state, allowing for a greater volume of oxygen to be stored and used compared to traditional gas tanks. Solid State systems, which use chemically generated oxygen, provide a reliable source of oxygen that activates on demand.

OBOGS, or On-Board Oxygen Generating Systems, are increasingly common in modern aircraft, allowing for the generation of oxygen from the ambient air; this eliminates the need to carry large oxygen tanks.

The other choices contain components or types of oxygen systems that are not commonly recognized or do not accurately represent widely accepted categories in aerospace physiology. For example, terms like Venturi or Green Gas do not refer to standard oxygen delivery systems. Understanding these accepted terminology
