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.







that seems… atypical? in australia at least, the average response time for a code 1 (most critical) emergency is 15-16min depending on the state
which is still super problematic for complete obstruction (your 5+5min might even be too high for a complete obstruction)
but 45min would make the ambulance service as a whole basically a useless concept
