Epinephrine auto-injectors for acute asthma as well as anaphylaxis

Would the three children described by Mark Levy et al and many others who died have survived if they'd had multiple epinephrine (adrenaline) intramuscular (IM) injections? Former President Obama legislated in 2013 for epinephrine auto-injectors in educational establishments for acute asthma attacks, as well as anaphylaxis, with a Good Samaritan clause. The National Review of Asthma Deaths recommended auto-injectors for asthmatics who survived a first life-threatening attack. In the thunderstorm epidemic in Victoria, Australia, in November 2016, paramedics gave IM epinephrine repeatedly to enable patients to survive until hospital arrival. UK paramedics will also give IM epinephrine to life-threatened patients with asthma.
