Diffusion.
If you held your breath, the concentration of oxygen in your lungs would decrease. The concentration of carbon dioxide would increase in your lungs.
The concentration of oxygen in waters decreases.
The oxygen concentration in the atmosphere today (which is at about 21%) has been at its current level for the past 400 million years.
Oxygen consternation is the most important for patient. Oxygen concentrate provides oxygen to the patients who require more oxygen than normal air
For resuscitation use 100 % - the kids hypoxic or you wouldn't be doing a resuscitation.
The concentration of oxygen inhaled depends upon the prescribed flow rate and the ventilatory minute volume (MV).

There are two main concerns when using oxygen on new born babies. One is oxygen toxicity, the other is meeting the babies oxygen requirements. On one hand, oxygen can actually be toxic, especially to pre-term babies from 32 weeks gestation and lower. High FiO2's(fraction of inspired oxygen) may even cause blindness (ROP), and Intracerebral bleeds (ICH). Secondly, the baby must have sufficient O2 to meets its bodies demands. I told you this so you know there is a difference in term newborn, and pre-term, oxygenation requirements. So, the simple answer to a complicated scenario is, apply the minimum FiO2 that will address the babies requirements. This is called oxygen titration.
Soil air has a higher concentration of Carbon Dioxide; plants feed on this and convert it into Oxygen during Osmosis, which is why there is a higher concentration of Oxygen in the atmosphere.
The concentration of oxygen in water is 88,88 %.
The concentration of oxygen decrease.
The concentration of oxygen decrease.
Diffusion.
If oxygen decreased, ozone will decrease. It is because ozone is made from oxygen.
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
Increased concentration of oxygen
