Correct answer: B — Monitor saturation during transfer and give oxygen if hypoxaemia develops

The best answer is “Monitor saturation during transfer and give oxygen if hypoxaemia develops”. Routine oxygen is not indicated in normoxaemic acute coronary syndrome. Continue close monitoring and give oxygen if hypoxaemia or another oxygen indication develops. Hyperoxia does not replace reperfusion and can distract from a time-critical PCI pathway. GTN response does not determine oxygen need, and transfer should not be delayed to achieve a saturation of 100%.
