What is a key complication of high-flow oxygen therapy?

High-flow oxygen therapy, while essential for correcting hypoxemia and improving patient outcomes in various respiratory conditions, can lead to a significant complication known as oxygen toxicity. This occurs when the body is exposed to high concentrations of oxygen for extended periods.

Oxygen toxicity primarily affects the lungs and the central nervous system. In the lungs, excessive oxygen can produce reactive oxygen species that result in inflammation and damage to the alveoli, potentially leading to acute respiratory distress syndrome (ARDS). For the central nervous system, prolonged exposure can cause symptoms ranging from visual and auditory disturbances to seizures and even loss of consciousness.

Recognizing the potential for oxygen toxicity is important, especially in settings where high-flow therapy is utilized. This awareness ensures that healthcare providers monitor patients closely and adjust oxygen delivery as necessary to prevent harmful effects while still achieving therapeutic goals.
