In the case of a female patient with cystic fibrosis who presents with low SpO2, what should be your initial intervention?

Administering oxygen is a crucial first step for a patient presenting with low SpO2, particularly in cases such as cystic fibrosis, where airway obstruction and respiratory distress are common issues. Low oxygen saturation indicates that the patient's body is not receiving adequate oxygen, which can lead to hypoxia and further complications. Administering supplemental oxygen can quickly improve her oxygenation status, alleviating immediate respiratory distress and providing essential support while further interventions are assessed.

Oxygen therapy is typically one of the first interventions used in respiratory emergencies because it is non-invasive, easily administered, and can rapidly enhance the patient’s hypoxemia. Once oxygenation has been addressed, additional measures such as the use of bronchodilators or suctioning can be considered based on a comprehensive assessment of her condition.
