 Trimix (breathing gas)

Trimix is a breathing gas mixture used in scuba diving that consists of three main components: oxygen (O2), nitrogen (N2), and helium (He). It is specifically designed to reduce the risks associated with deep diving, particularly narcosis and oxygen toxicity. ### Composition: - **Oxygen (O2):** The percentage of oxygen in trimix is typically lower than what is found in regular air to mitigate the risk of oxygen toxicity at depth.
