What must be monitored during oxygen therapy to prevent oxygen toxicity?

Monitoring oxygen concentration and the duration of therapy is essential to prevent oxygen toxicity because excessive levels of oxygen can lead to cellular damage, particularly in the lungs and central nervous system. Oxygen toxicity occurs when there is a high concentration of oxygen for a prolonged period, leading to oxidative stress and potential injury to tissues. For example, concentrations above 60% can be harmful if used for extended durations.

It is crucial to adjust the dosage according to the patient’s specific needs and to monitor how long the patient is receiving high concentrations of oxygen. This helps ensure that therapeutic benefits are achieved while minimizing the risk of adverse effects associated with prolonged exposure to elevated oxygen levels. Regular assessment ensures that patients receive the appropriate amount of oxygen without exceeding safe limits, thereby protecting them from the potential harmful effects of oxygen toxicity.
