Heroic student saves choking friend with the Heimlich maneuver

A Wisconsin high school freshman became a hero earlier this week after he saved a choking classmate.
Ian Brown was eating lunch with friends at La Crosse Central High School on Wednesday when pal Will Olson started choking after laughing at a joke.
Brown noticed Olson's face and neck were changing color and jumped into action to perform the Heimlich maneuver.
He was able to dislodge a cheese curd from Olson's throat, and took him to the nurse's office to make sure his airway was clear.
'I just went and did it,' Brown told WIZM. 'It was do first and think later. Afterwards, we were just like, 'Alright, let's talk about what just happened.' It all happened really quick.'
Brown said he and his friends were telling jokes when Olson started choking after taking a deep breath in while laughing and eating at the same time.
The group had just gotten to the cafeteria after going across the street to grab food from a Chinese buffet for lunch.
'We couldn't tell if he was choking right away,' Brown told WIZM. 'He had kind of a laugh with it.
'And then his face stared turning purple and I saw his hands go around his neck and I was like, "I need to get over here and help him out".'
Central school nurse Kim Mahlum later told police that several teens at the cafeteria table thought the boy was joking when he started coughing and motioning that he couldn't breathe.
