yes
the oxygen level decreases
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
The oxygen level remains about the same, but the density of the air is reduced.
Hypoxia
yes
Different doctors consider different levels as low. Though 84 to 92 is an acceptable level according to many and others say lower then 92 is not good.
If you are talking about a Human Being, it is the level of Oxygen in that persons Blood. That person had a Oxygen Saturation Level in their Red Blood Cells of 92% Depending on Age and overall Health the Optimal Range is from 94% to 98%. Please note that this is a average guide only, if you want further detailed info, or if you are worried, please contact your doctor.
It means that you blood is not carrying enough oxygen for your whole body and brain to work well. A level of above 95 is satisfactory. Brain uses most oxygen in the whole body
If it is your oxygen level how old are you? and IRS ok its not perfect but you should be fine if it doesn't go back up to 100 go see your doctor.
If you refer to the blood oxygen level in humans, yes, that is a good level. In that context it is given as a percentage and in the human blood where it goes from 90 to 98 normally in a healthy person
very low, the person requires ventilatory support. Blood SpO2 level should be above 90%, and should be aimed to 92%~98%
That is reasonably low on air, it needs to be investigated.
The oxygen sensors are located in the exhaust pipes.
yes if it will fit in the trunk i think that the trunk is bigger in the 92 so it should be ok
the oxygen level decreases
no it is not send him to the hosipital immediatly or he could be facing death
