O2 Gas and its Sensor

Intro to Oxygen Gas

Oxygen gas is a chemical compound with the formula O2. It can be very difficult to detect when O2 levels are outside of regular concentrations, as it is colorless, odorless, and flavorless. Oxygen is an excellent oxidizing agent, and can either cause or intensify fires when combined with many different compounds in the atmosphere. Oxygen is non-combustible itself, but is a key part of the fire triangle that leads  to combustion of other compounds or materials. The biggest threat oxygen poses is when there is not enough of it; oxygen deficiencies create incredibly dangerous circumstances. This makes it imperative to frequently test confined spaces for oxygen levels, so that workers are not put into vulnerable positions. Oxygen enrichment is another risk factor due to the increased chance of combustion and explosions.

Oxygen exists in several forms, including molecular oxygen (O2), which is the most common oxygen forms in Earth's atmosphere, and liquid oxygen, which is used in various industrial applications. Pure oxygen forms is rarely found in nature but can be produced through various methods. Free oxygen, which is not bound to other elements, plays a crucial role in many biological and chemical processes. In the human body, oxygen is essential for cellular respiration and maintaining proper blood flow. The body's red blood cells transport oxygen to tissues and organs, while simultaneously removing carbon dioxide, a waste product of metabolism. Oxygen produced by plants through photosynthesis has been crucial in the evolution of life on Earth, allowing organisms to evolve free oxygen utilization mechanisms.

The human body relies on oxygen for survival, with our respiratory system extracting this vital element from earth's atmosphere. Oxygen produced by plants and algae maintains the breathable air we depend on. Once inhaled, produced oxygen dissolves into our bloodstream, facilitating crucial blood flow throughout our bodies. While we typically breathe gaseous oxygen at atmospheric pressure, oxygen can also exist in other forms. For instance, liquid air, when separated, yields liquid oxygen. The composition of our atmosphere, primarily nitrogen and oxygen, along with trace amounts of other gases like nitrogen oxides, creates a specific partial pressure of oxygen that our bodies have evolved to utilize efficiently.

Reactive oxygen species, which are forms of oxygen that are highly reactive, can be both beneficial and harmful to living organisms. In some cases, they play a role in the body's immune response, while in others, they can damage organic compounds and contribute to oxidative stress. In industrial settings, inert gases are often used to displace free oxygen in certain processes or environments where the presence of oxygen could be dangerous. However, it's crucial to maintain proper ventilation and monitoring systems to ensure that workers are not exposed to oxygen-deficient atmospheres, which can rapidly lead to loss of consciousness and death.
