Room Air O2 Concentration

Two oxygen concentrators have been tested.

Room air o2 concentration.

Indicator for the room air quality is the concentration of specific gases in air. Fio 2 the fraction of inspired oxygen is defined as the percentage or concentration of oxygen that a person inhales. They are able to produce both high oxygen concentrations 95 oxygen at 2 l min and high flow rates 10 l min with 40 oxygen which remained stable for one week. The minimum oxygen concentration in the air required for human breathing is 19 5 percent.

Air is a mixture of several gases where the two most dominant components in dry air are 21 vol oxygen and 78 vol nitrogen. The atmospheric air that we inhale on a day to day basis is made up of 21 oxygen 78 nitrogen and 1 trace elements such as argon carbon dioxide neon helium and methane. Since both of these elements are diatomic in air o 2 and n 2. Carbon dioxide co 2 carbon monoxide co oxygen o 2 ozone o 3.

In offices can easily cause tiredness poor powers of concentration and even diseases to people. The concentration of water vapor a greenhouse gas varies significantly from around 10 ppm by volume in the coldest portions of the atmosphere to as much as 5 by volume in hot humid air masses and concentrations of other atmospheric gases are. An unsatisfactory room air quality of indoor rooms e g. The three major constituents of earth s atmosphere are nitrogen oxygen and argon water vapor accounts for roughly 0 25 of the atmosphere by mass.

Each cell uses and requires oxygen to thrive. After 24 hours of continuous use neither machine concentrated toxic gases from room air in a city. Most of the time the air in the atmosphere contains the proper amount.
