What is the immediate treatment for a patient presenting with chest pain and respiratory distress?

In a scenario where a patient presents with chest pain and respiratory distress, providing oxygen support is crucial due to the potential for hypoxia or inadequate oxygenation, which can occur in numerous cardiac or respiratory emergencies. Administering oxygen helps increase the amount of oxygen available to the tissues, which is essential for maintaining organ function, especially under stress conditions like chest pain and respiratory distress.

While pain relief is important and can help manage the patient's comfort, it does not address the immediate threat of oxygen deprivation. Starting CPR is necessary only if the patient is unresponsive and not breathing, making it less appropriate in this context since the patient is exhibiting respiratory distress rather than cardiac arrest. Positioning the patient supinely might not be beneficial; elevating the head and torso can assist with breathing difficulties. Therefore, the priority in this situation should be to provide oxygen support to stabilize the patient's condition.
