Oxygen and Staying Alive

What does oxygen really mean to me?


Basically, in order to keep living and staying alive YOU, and I, need four fundamental things.

We needWater, Protein, Energy, and Carbohydrates. These 4 things are composed of:


Water   =                      OXYGEN + Hydrogen

Protein =                      OXYGEN + Carbon + Nitrogen + Hydrogen

Energy =                      OXYGEN + Carbohydrates

Carbohydrates =          OXYGEN + Hydrogen + Carbon


All of the living cells in our bodies require oxygen in order to function, and it is clear that oxygen is involved in all of our metabolic processes. Indeed it has been estimated that oxygen is responsible for approximately 80% of all our metabolic energy production.


In order to operate at a normal level, as adults, you and I need to maintain an oxygen level of 95%-100% of saturation in our blood. I must declare here that I have a vested and personal interest in the matter as I have been fitted with a heart pacemaker. I also have an Oxygen level, and pulse meter which I periodically clip onto my finger to monitor my blood system. If the blood oxygen saturation is too low then it will cause such things as:


  • Reduced brain function, poor decision making, depression, memory loss, reduction of consciousness
  • Fatigue, muscle aches and pain, general body weakness
  • Poor digestion, acidic stomach
  • Decrease in effectiveness of immune system and, reduced ability to fight infections
  • Reduction in illness repair and recovery systems

Specifically these effects alone affect my quality of life and yours.

Generally they contribute to an overstretched health and hospital system.

We need our brains functioning at their best to survive in this world

We need our full health defenses to fight off the increasing number of ailments and diseases




We must get all the oxygen only from the air we breathe. It should be plentiful & unpolluted.


      IS IT ???????          AND                FOR HOW LONG WILL IT STAY THAT WAY???


A reasonably fit person might be able to exist without:


  • Food for about -------------------------------------------------           40 days
  • Water, assuming a temperature of 80 degrees f / 26,7C ---                    9-10 days
  • Oxygen ---------------------------------------------------------                        a matter of minutes


  I NEED MY OXYGEN                                    YOU NEED YOUR OXYGEN


Where do I get my oxygen from?

                        We that, is you and I, get all our oxygen from the air we breathe.


Oxygen -What We MUST Know About It


Mass O2 is by mass, the third most abundant element in our universe. It readily forms compounds with almost all other elements. Initially there was no free oxygen in our atmosphere. Oxygen was, and is, locked into the earth’s:

crust where it makes up 49%  of its mass

oceans where it makes up 86% of its mass

In the crust it readily bonds with iron. In Western Australia a man flying his aircraft around noticed the redness of huge areas of the country. He was right it was iron ore. The man was arch-conservative Lang Hancock. His daughter Gina is currently the richest woman in the world.

It does pay to keep your eyes open and see what others are not seeing doesn’t it?

In the water at 250 C at 1 atmosphere of pressure 1 litre of:

Fresh water can absorb about 8.63mg of O

Sea water can absorb about 7mg


Free Oxygen  It is because of this propensity to bond that free oxygen only occurs in our atmosphere as the result of photosynthesis, by living organisms. The majority of free O2 is not actually produced by the trees and other land vegetation, as is generally thought. Land vegetation only contributes about 10% of the free O2, the majority, that is close to 90%, is now known to be produced in the sea, by phytoplankton, notably by the tiny but very beautiful diatoms.  The production of free oxygen first started about 2.5 - 3 billion years ago with stromatolites formed from blue-green algae.


Ozone In its form as O3 it is called ozone, which at high altitudes protects us from deadly ultraviolet radiation. However ozone at low altitudes is a pollutant which attacks the nasal and lung linings. It is often generated by electrical sparking in machines though much is the result of petrol driven machines and vehicles.


Composition The atmosphere is not of exactly the same composition everywhere, similarly to the oceans there are eddies, currents, zones, and pockets, which may differ from one to the other in their compositions.

Generally speaking, the composition of air at sea level is:

78.1% Nitrogen

20.9% Oxygen

0.93% Argon

0.034% Carbon dioxide

Our atmosphere is higher at the equator (13-16km) than at the poles (7-8km)
