There are five key elements that can be found in the air: nitrogen consists of 78.08 percent, up 21 percent oxygen is 0.04 per cent carbon dioxide, water vapor is composed of 1 percent argon and consists of 0.93 to 94, while the other trace minerals complete components in the air. Of all the components of air, oxygen is necessary for people to survive.

Usually take oxygen for granted. We still believe that when we breathe, there is a sufficient amount of oxygen we have left to breathe. But because of global warming, some studies have shown a result of reduced oxygen level from 21 to 19 percent.

A reduced level of oxygen is bad and dangerous to our health. It can lead to serious chronic medical conditions. As they use oxygen to help eliminate toxins and human waste without it may die within minutes. Global warming is a phenomenon that has been shown to reduce the level of oxygen in the air we breathe.

Oxygen deficiencies are all related to the components in the air. Some are single because of the bad habits of an individual. People who have lived a sedentary lifestyle, drinking fluoridated water and eating processed foods?cooked or suffer from lack of oxygen. Symptoms such as dizziness, circulatory problems, infections, anxiety, weakness, fatigue and low immunity may be present in this state.

People should be aware of your health and oxygen levels. One of the recommendations as a caregiver is usually dictates the use of monitoring tools to control the level of oxygen blood oxygenation.

People typically use an oximeter, which is simple, compact and easy to use. Oximeter is a noninvasive procedure that not only used to control the level of blood oxygenation, but is also used to check the pulse and intensity.

Each component of the air has its own features and applications. But for human life, the most important of all oxygen.
