What is a primary concern when using high-flow oxygen therapy?

When administering high-flow oxygen therapy, a primary concern is the risk of oxygen toxicity. This condition can occur when an individual receives high concentrations of oxygen for an extended period, which can lead to damage in the lungs and central nervous system. The primary physiological mechanism behind oxygen toxicity is the generation of free radicals due to excessive oxygen levels, which can lead to lung damage, pulmonary inflammation, and impaired gas exchange.

Understanding the potential adverse effects of high-flow oxygen is crucial for healthcare providers, as it allows for monitoring and managing patients to avoid complications that can arise from prolonged exposure to high oxygen levels.
