What is the composition of oxygen?

Under normal conditions of temperature and pressure, theoxygen is in the form of an odorless and colorless gas, dioxygen, with the chemical formula O2. Within this molecule, the two atoms ofoxygen are chemically bonded to each other in a triplet state.

Why O2?

choose O2? O2 is a creator of oxygen bubbles in the daily life of the whole family! Human, dynamic, expert, O2 is a breath of fresh air that restores free time, time for oneself, which frees up time-consuming tasks, and allows you to live your life to the full by taking care of what matters( nt).

What is the main constituent of air?

How do I know if my oxygen level is correct?

Most healthy people have an SpO2 reading of 95% with a PR of 70-80 beats. Here are the ranges of oxygen saturation that determine if your oxygen level is correct: Below 90%: it is insufficient.

Why do an oxygen saturation analysis?

This analysis of oxygen saturation is particularly used in people with a respiratory pathology. Blood supplies oxygen to all tissues and carries carbon dioxide to the lungs for elimination from the body. A small amount of oxygen is carried by the plasma.

How to measure the degree of oxygen in the blood?

In respiratory dysfunction, the blood contains less oxygen and more carbon dioxide. The degree of oxygenation can be measured with two means: oxygen saturation (SaO2, measured in arterial blood, SpO2 measured by a pulse oximeter or saturometer) and partial oxygen pressure (PaO2).

How to measure the degree of oxygenation?

The degree of oxygenation can be measured with two means: oxygen saturation (SaO2, measured in arterial blood, SpO2 measured by a pulse oximeter or saturometer) and partial oxygen pressure (PaO2).
