When I worked with safety regulations on the mines we sometimes arrived at a situation we called eye blind. Something that appeared to serve the purpose for safety but in reality was a just a token for regulations appearances sake, like the wrong type of fire extinguisher, empty first aid boxes and u/s safety equipment. I have held various first aid certificates since the late 70's and have a diploma in mine safety management. Regarding O2 admin course I did, it was worth about a fiver, maybe less. A decent dive medic course it isn't. Some people think you can teach O2 admin without physically practising using the equipment. Although reading a book, or looking at it is better than nothing, I thought I was paying for training and to me the only acceptable effective training is hands on. IMO most of the 3 litre kits on sale are inadequate for people who dive in out the way places. You have a diver showing the effect of deco sickness, ideally you immediatly put the patient and the buddy on O2 as they have both done the same dive. For dive planning purposes BSAC regard the average surface consumption rate as 25 litres a minute and the average O2 cylinder pressure is 200 bar then with 2 breathing from a 3litre cylinder it lasts around 12 minutes. People in pain may or may not be doing a lot of fast shallow breathing. You may have a lower consumption rate and I have no knowledge of how adequate 25 litres a min is as an average consumption for estimating purposes.
