A 44-year-old female with atrial fibrillation shows palpitations and shortness of breath. What should you do?

In this scenario, the patient is experiencing palpitations and shortness of breath due to atrial fibrillation. Administering oxygen by nasal cannula is appropriate because the patient is likely experiencing some degree of hypoxia given her symptoms. Nasal cannula provides a more comfortable and less invasive means of delivering supplemental oxygen, which can help alleviate her shortness of breath and improve her oxygen saturation levels.

Oxygen is an essential part of managing any patient who exhibits respiratory distress or cardiovascular compromise. The nasal cannula allows for moderate levels of supplemental oxygen, which may be sufficient for this patient, especially if she is alert and responsive. Keeping the airway open and ensuring adequate oxygenation is crucial in managing her symptoms and preventing further complications.

While transporting the patient is necessary and administering oxygen can be performed during transport, using a nasal cannula allows for more immediate relief of her symptoms. Other treatments like administering aspirin may not be suitable given her current presentation, as it does not address the immediate need for oxygen due to her apparent distress.
