What is the recommended oxygen delivery method for a patient with respiratory distress?

The recommended oxygen delivery method for a patient experiencing respiratory distress is the non-rebreather mask. This choice is correct because the non-rebreather mask provides a high concentration of oxygen, which is crucial for patients who are struggling to breathe and require immediate intervention.

The mask covers the patient's nose and mouth and has a reservoir bag that allows for the delivery of nearly 100% oxygen while preventing the re-inhalation of exhaled air. This is particularly important in respiratory distress situations, as the patient may be unable to adequately oxygenate their blood.

In contrast, while a nasal cannula can be used for patients with milder respiratory issues, it generally delivers a lower concentration of oxygen and may not be sufficient for someone in significant distress. The bag-valve mask is typically employed for patients who are unable to breathe effectively on their own, or who are unconscious, as it requires manual assistance from the responder. The simple face mask also delivers oxygen but is less effective than the non-rebreather mask in providing the necessary concentration required in urgent situations.

Therefore, the non-rebreather mask is the most appropriate choice for ensuring adequate oxygenation in patients with respiratory distress.
