What should be done if a patient is in respiratory distress and their oxygen levels are low?

Administering oxygen with the appropriate device is essential in cases of respiratory distress and low oxygen levels because it directly addresses the problem of hypoxemia, or insufficient oxygen in the bloodstream. When a patient experiences respiratory distress, it is crucial to support their breathing and ensure that adequate oxygen is delivered to their tissues.

By providing supplemental oxygen, you can help increase the amount of oxygen available for the patient to breathe, which can alleviate symptoms of distress and prevent potential complications. Different oxygen delivery devices, such as nasal cannulas or non-rebreather masks, can be chosen based on the patient's condition and severity of oxygen deprivation.

In this situation, monitoring for changes and waiting does not provide immediate relief for the patient. Encouraging coughing may be helpful in some cases, but it is not a primary intervention for low oxygen levels or distress. Providing fluids generally does not address the immediate issue of the patient's respiratory status and could potentially lead to fluid overload in certain conditions. Therefore, administering oxygen is the most appropriate intervention to manage the patient's respiratory distress effectively.
