For a patient with a history of COPD presenting with low SpO2, what is the FIRST intervention?

In managing a patient with COPD who presents with low SpO2, the priority is to address the hypoxemia, or low oxygen saturation. Providing oxygen is essential as it directly targets the low level of oxygen in the blood, which is critical for sustaining organ function and preventing further respiratory distress.

Oxygen therapy can improve SpO2 levels rapidly, allowing for better oxygen delivery to the tissues, which is especially important in patients with respiratory conditions like COPD that can lead to increased work of breathing and exacerbations. While bronchodilators play a significant role in relieving bronchospasm and improving airflow, they are typically not the immediate response to low SpO2 levels.

Suctioning and chest physiotherapy are modalities that may be indicated in specific situations where secretions are causing obstruction but are not the immediate priority when the first concern is hypoxia. Addressing oxygenation first provides a foundation to then consider further interventions, such as administering bronchodilators, if bronchospasm is suspected after initial oxygen delivery.
