Q: Oxygen should be given to all suspected coronary syndrome patients, even if their saturation is normal.

True or False?


Answer: False

Traditionally, high flow oxygen with recommendation of  4 L/min was recommended for everyone with suspected coronary syndromes but recent data shows that routine use  of oxygen in all coronary syndrome may lead to increased mortality and infarct size. Therefore, oxygen is recommended only if oxygen saturation is low or patient is in respiratory distress.
