Hyperoxia is a condition where there is an excess of oxygen in the body tissues. This can occur when a person breathes in oxygen at higher than normal atmospheric levels, often through medical treatments or in specific environments like underwater diving. While oxygen is essential for life, too much can lead to toxicity and various health issues. Symptoms of hyperoxia may include visual disturbances, respiratory problems, and even seizures in severe cases. It is important to monitor oxygen levels, especially in clinical settings, to prevent complications associated with excessive oxygen exposure. Understanding the balance of oxygen is crucial for maintaining health and safety in situations involving high oxygen concentrations.
