In which lung expansion injury would emergency oxygen be administered?

In the case of a pneumothorax, emergency oxygen is administered primarily because this condition involves the presence of air in the pleural space, which can collapse the lung and significantly impair gas exchange. When the lung collapses, the individual may experience decreased oxygenation and respiratory distress, necessitating immediate intervention.

Administering oxygen can help to improve tissue oxygenation by increasing the amount of oxygen available in the bloodstream. In cases of tension pneumothorax, where the pressure builds up, providing supplemental oxygen can assist in stabilizing the patient until further medical intervention, such as needle decompression or chest tube insertion, can be performed.

In contrast, while asthma attacks, aspiration pneumonia, and frostbite might also require oxygen in certain cases, the urgency and mechanism behind the pneumothorax make it particularly critical to administer emergency oxygen promptly to manage the potential for rapid deterioration in the patient's condition.
