Conc'n of O2 is 20 %
For nirogen it is 79%
Other gases us 1% , this included water vapour, carbon dioxide, the noble(inert) gases.
The partial pressure of oxygen p(O2) = 20/100 = 1/5 = 0.2
Oxygen diffuses from air into blood through the process of simple diffusion. This occurs in the lungs where oxygen moves from areas of high concentration in the alveoli to areas of lower concentration in the blood capillaries. The concentration gradient allows oxygen to pass through the alveolar walls and enter the blood.
No, wind does not take away oxygen. Wind is the movement of air in the atmosphere and does not affect the overall concentration of oxygen in the air. Oxygen is one of the primary components of air and is not removed by wind.
40% If a self-inflating bag is connected to a 100% oxygen source, oxygen enters the bag through tubing connected between an O source and the O inlet port on the bag. However, each time you squeeze it, air (O concentration 21%) is drawn into the bag through the air inlet. The air is dilutes the concentration of O in the bag. -NRP Textbook AHA and AAP, 6th Edition. pg. 118-119
No, the ideal ratio of oxygen to nitrogen in the air is already balanced to support human life. Increasing the oxygen concentration can be harmful as it may lead to oxygen toxicity, while decreasing the nitrogen concentration can lead to nitrogen narcosis.
A patient breathing room air should be receiving approximately 21% oxygen. This is the normal oxygen concentration present in the air we breathe.
Concentration of oxygen in dry air is 20,946 %.
21 percent.
Exhaled air contains 16% oxygen and 21% when inhaled.

It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
