If they knew he needed an inhaler they probably would’ve used it or located the dropped inhaler. I’m guessing he wasn’t able to communicate at that point so they just had to guess what the problem was.
Yup, probably. Very sad. As a parent of a child with Asthma, this is a nightmare. Also, this was a severe attack, as usually, it takes time to reach that point. But dust and other factors can trigger.
