What is the recommended approach if a patient shows signs of oxygen toxicity?

The recommended approach if a patient shows signs of oxygen toxicity is to reduce the concentration of oxygen and assess symptoms. Oxygen toxicity can occur when a patient receives oxygen at higher concentrations for extended periods. This condition can lead to symptoms such as difficulty breathing, chest pain, and central nervous system effects, which may necessitate immediate attention.

By reducing the concentration of oxygen, you can help mitigate the risk of further toxicity. Lowering the oxygen levels decreases the partial pressure of oxygen that the patient's tissues are exposed to, thereby reducing the likelihood of cellular damage associated with excess oxygen. Following this adjustment, continuous assessment of the patient's symptoms is crucial to monitor their response and ensure they are stabilized.

Other approaches, such as switching to nebulizer therapy or increasing the flow rate, do not directly address the underlying issue of toxicity and could potentially exacerbate the patient's condition. Continuing with the current therapy without adjustments can further jeopardize the patient's safety, making it imperative to modify the oxygen levels in response to their symptoms.
