In the Periodic Table the element below oxygen is Sulphur.
An oxygen deficient atmosphere is one that lacks a sufficient amount of oxygen to support human or animal life. It can occur in environments where oxygen is depleted, such as in confined spaces or areas with high levels of carbon dioxide, gases, or chemicals that displace oxygen. Breathing in an oxygen deficient atmosphere can lead to suffocation or loss of consciousness.
Magnesium and oxygen, as shown below: 2Mg + O2 ------> 2MgO
Aldosterone
In group 6A, oxygen is at the top and sulfur is below oxygen. Ionization energy decreases going down a group. groups run vertically
Hypoxia: Hypo = below, ox = presence of oxygen "Below oxygen" or "below normal oxygen levels" Hypoxia means low tissue oxygen level. Or oxygen levels below normal in the tissues.
Any levels of the building below ground level are normally considered basement. In larger buildings they are sometimes referred to as sub-levels.
Unsafe oxygen level is below 90% oxygen saturation.
Hypoxemia means having below normal oxygen levels in the blood.
A 'storey' is a level so yes. Think multi-storey car parks that have levels below ground.
The basement is the level in your house below ground level. To say it another way, you would be below the ground if you were in a basement.
One or more floor of a building that are completely below the ground floor is basement. A floor of a building that is half below ground, rather than entirely such as a basement is semi basement.
If oxygen levels fall below 19.5% during a permit-required confined space entry, all entrants must stop work immediately and leave the confined space. No one may reenter that space until testing shows that adequate oxygen levels have been restored.
There is 13-16% oxygen in expired air but it depends on your size. See the link below.

Basement/cellar.
A basement of a house is the room or space that is below ground level. A basement appliance that can heat your house is a furnace.
