In acute coronary syndrome, what is the target SpO2 range to aim for oxygen therapy?

Explanation:
In acute coronary syndrome, oxygen is used selectively—only if the patient is hypoxemic or in respiratory distress. When oxygen is given, the goal is to maintain adequate oxygen delivery without causing harm from too much oxygen. A SpO2 of about 94–96% provides enough oxygen for the heart and tissues while avoiding hyperoxia, which can cause vasoconstriction and oxidative stress. Targets lower than this risk tissue hypoxia, while higher targets (too close to 100%) offer little extra benefit and may be unnecessary or harmful. So the recommended range is 94–96%.
