When you are an emergency oxygen provider, you know what to do in an emergency. When a diver surfaces and complains about pain in the joints or a sleepy hand, you will know this is a symptom a decompression sickness and you will provide him with pure oxygen. It's one of those courses that are very useful, but you hope you will never need to apply in real life. 

During the course we will get to know different systems and methods to provide oxygen and we will learn how to use them. There are no dives, but we will have plenty of time to practise on land.
