Tom, you provided care and reassurance for not only the patient but all her assembled family too. That probably helped almost as much as the nebuliser and oxygen in its own way. As an asthmatic myself, having calmness and authority around me in times of bad attacks makes a massive difference. Someone assuring you that you will be ok, and providing the medication to back that statement up makes all the difference in the world. Well done, and London is a safer place for having YOU in the RRV.
