What symptom is commonly associated with pulmonary oxygen toxicity?

The burning sensation on inspiration is a well-documented symptom of pulmonary oxygen toxicity, particularly when an individual is exposed to elevated levels of oxygen for prolonged periods. This condition arises due to the reactive oxygen species formed at high oxygen pressures, which can irritate and damage the lung tissues. The inflammation from this irritation manifests as a burning feeling during inhalation, making it a critical sign for divers and others exposed to hyperoxic environments to recognize.

While the other symptoms like dry throat, persistent cough without phlegm, and fatigue can occur with various respiratory conditions or can be related to high levels of oxygen exposure, they are not as directly linked to the immediate and acute effects of pulmonary oxygen toxicity as the burning sensation during respiration. Understanding this symptom helps divers and dive supervisors monitor and manage the risks associated with hyperbaric oxygen therapy or deep-sea diving operations effectively.
