Which measure is important to take if a patient is experiencing angioedema?

Administering 100% oxygen is crucial when a patient is experiencing angioedema, especially if there are concerns about airway compromise due to swelling. Angioedema can cause significant swelling in the face, throat, and airways, leading to potential breathing difficulties. Providing high-flow oxygen helps ensure that the patient receives adequate respiratory support during this critical time.

In cases of angioedema, the airway can be at risk of becoming obstructed, necessitating immediate intervention to maintain oxygenation. Supplemental oxygen can also help alleviate hypoxia, improving the overall condition of the patient until further medical assistance can be rendered, such as administering antihistamines or corticosteroids that will address the underlying cause of the swelling.

It is vital to recognize that other measures, while they may seem beneficial in other contexts, do not address the critical issue of impending airway obstruction as effectively as providing supplemental oxygen does.
