When should supplemental oxygen be administered to a patient with shortness of breath?

Supplemental oxygen should be administered to a patient with shortness of breath when they are in respiratory distress because this condition often indicates that the patient is either not getting enough oxygen or is struggling to breathe adequately. Respiratory distress can manifest in various forms, including rapid breathing, use of accessory muscles, and changes in mental status, all of which signify a potential oxygenation issue. By providing supplemental oxygen during respiratory distress, paramedics can help mitigate the risk of hypoxemia and improve the patient's overall condition while working towards further evaluation and management.

In this context, simply waiting for a specific oxygen saturation level, like 90%, can delay the necessary intervention required to help a patient who is already exhibiting signs of distress. While patient requests for oxygen could be a valid consideration, it is essential to base the decision to administer oxygen on clinical observations and the patient's state rather than solely on their requests. Responding immediately upon arrival without assessing the situation could lead to unnecessary treatments or overlook the need for prompt management when a patient is already struggling to breathe. Therefore, focusing on the patient's respiratory status is crucial for timely and effective oxygen therapy.
