Why YSK:
Despite choking being an emergency, until recently there has been limited high-quality evidence to guide bystanders on the most effective way to help. Techniques like abdominal thrusts (formerly known as the Heimlich maneuver), back blows and chest compressions or thrusts have existed since the mid-1900s but, until recently, recommendations were largely based on case reports rather than rigorous scientific data. This evidence gap is dangerous.
Bystander response is the primary driver of a choking person’s outcome, so ensuring people know the safest and most effective way to care for a choking person can save lives.

If you need more motivation to open the article, here is an interesting fact:
New research suggests back blows cleared choking obstructions in 72 per cent of cases, superior to both abdominal thrusts (59 per cent) and chest thrusts (27 per cent).


Interesting. I was eating at a restaurant with my mom a few years ago and she accidentally inhaled a piece of food which had the same diameter as her esophagus. It was terrifying. She just pointed at her throat and had this look on her face like she knew she was going to die. She stood up, turned around, and I did what I thought was the heimlich maneuver. I must’ve done it right, or got lucky, but it worked flawlessly. The food came flying out. I guess we’re in that 59%.
The same thing happened to my son. Luckily I had first aid training and actually knew how to do the Heimlich. I didn’t know that you were supposed to do back blows first though. When I learned, they just told me to go straight for the Heimlich.
