Felt like a bit much mucking around off topic. The information and practical could have been condensed to be one hour. Also, not safe &sound specific but it would be nice to see england timely progressing teachings. For just one example, many years ago other places have changed to teach DRS ABCD to include 'send for help' (get someone to call an ambulance) and 'defibrillator ' (rather than just DR ABC). The defib is an important step to optimise chances of survival , so it should be part of the mnemonic which people automatically revert to. I'm not sure if you have involvement of the continued development of the standardised course content but i think it is worth mentioning for if you do.
