Tony Stark has been what everyone calls a very overprotective parent.
He can't help it, though; he wants to be sure his son stays safe at all times.
So when he discovered Peter had asthma, through one of the most terrifying days of his life, he made Peter a custom watch that constantly monitors Peter's heart rate and oxygen levels, which would notify him if Peter's levels got too high.
It's only ever happened once since he made the watch, when Peter was in elementary school, and the local bully kept poking fun at Peter, causing him to have an anxiety/asthma attack.
So as soon as Tony got the notification that Peter's levels were astronomically high, Tony ran as fast as he could, calling Happy to pull the car around and to make it snappy.
Tony wasn't wasting a damn second to get to his son.
