How can oxygen toxicity be identified?

Oxygen toxicity can be identified through a range of symptoms, including confusion, seizures, and difficulties in breathing. When a person is exposed to high levels of oxygen, particularly at elevated pressures, it can lead to the generation of reactive oxygen species that may damage cellular structures. This disruption in normal brain function can manifest as confusion or altered mental status. Additionally, seizures can occur due to the central nervous system's sensitivity to excess oxygen. Respiratory difficulties arise as the lungs react negatively to high concentrations of oxygen over prolonged periods. These symptoms serve as critical indicators of oxygen toxicity, making them essential for healthcare providers to monitor in patients receiving high-flow oxygen therapy or hyperbaric oxygen treatment. Identifying these symptoms early can help prevent further complications related to oxygen exposure.
