What does the term "inert gases" refer to in medical use?

The term "inert gases" in a medical context refers to gases that do not react chemically under normal conditions, such as nitrogen. These gases are characterized by their stability and lack of reactivity, meaning they do not readily engage in chemical reactions with other substances in their environment. This property makes inert gases safe for various medical applications, as they will not interfere with chemical processes or cause unwanted reactions in the body.

In medical settings, inert gases such as nitrogen are often used to provide a protective atmosphere for certain procedures or to displace oxygen in environments where it needs to be controlled. Their non-reactive nature also makes them suitable for use in laboratory environments, where chemical interference can skew results or create hazards. The stability and safety of inert gases are essential in ensuring they can be used effectively without posing risks to health or safety.
