Hello, I'm an expert in respiratory physiology and toxicology. Let's dive into the question of whether too much oxygen can cause confusion.

Oxygen is essential for life, but like many things, it can be toxic in excessive amounts. A condition known as oxygen toxicity can occur when the body is exposed to high concentrations of oxygen for a prolonged period. This can lead to a variety of symptoms, including confusion.

The mechanism behind oxygen toxicity involves the formation of reactive oxygen species (ROS), which are molecules that can damage cells and tissues. High levels of oxygen can cause an overproduction of these ROS, leading to oxidative stress. This can affect the central nervous system, potentially causing cognitive impairments such as confusion.

However, it's important to note that oxygen toxicity is more likely to occur in situations where oxygen levels are significantly higher than what we breathe at sea level, such as in scuba diving or hyperbaric oxygen therapy. At normal atmospheric pressure, the risk of experiencing oxygen toxicity is very low.

In summary, while too much oxygen can theoretically lead to confusion due to oxygen toxicity, it is not a common occurrence under normal conditions.

It is important to wear your oxygen as your provider ordered it. If you start to experience headaches, confusion or increased sleepiness after you start using supplemental oxygen, you might be getting too much. Oxygen settings of 4 liters per minute or above can cause dryness and bleeding of the lining of the nose.read more >>
