What are the symptoms of oxygen overdose?

As a medical professional with expertise in respiratory health, I can provide you with information on the symptoms of oxygen overdose. Oxygen toxicity, also known as oxygen intoxication, occurs when the body is exposed to high levels of oxygen for an extended period. The central nervous system is particularly sensitive to oxygen toxicity, and the symptoms can vary depending on the level of exposure and the individual's health. The most common symptoms of oxygen overdose include: 1. Visual Changes: This can manifest as a narrowing of the visual field, often referred to as tunnel vision. 2. Tinnitus: A high-pitched ringing or buzzing in the ears is a common symptom. 3. Nausea: Feeling sick to the stomach can occur as the body reacts to the excess oxygen. 4. Twitching: Involuntary muscle movements, particularly around the face, may be observed. 5. Behavioural Changes: These can include increased irritability, anxiety, and confusion. 6. Dizziness: A feeling of lightheadedness or unsteadiness can be a sign of oxygen toxicity. It's important to note that these symptoms can progress to more severe conditions such as seizures, loss of consciousness, and in extreme cases, can lead to respiratory arrest and death. If you suspect oxygen toxicity, it's crucial to seek medical attention immediately.

Central nervous system oxygen toxicity manifests as symptoms such as visual changes (especially tunnel vision), ringing in the ears (tinnitus), nausea, twitching (especially of the face), behavioural changes (irritability, anxiety, confusion), and dizziness.
