Study Details

Brief summary:

Foreign body airway obstruction (FBAO, choking) is a life-threatening emergency requiring time-sensitive treatment to prevent severe injury or deaths. Traditional treatments taught in first aid courses include abdominal thrusts, back blows, and chest compressions or thrusts. Currently, first aid guidelines recommend different treatments for adults, child and infants. Until recently, data on these techniques was limited to case series from the late 1900's. To further improve our knowledge of which treatment is most effective and safest for patients, this study will collect data on choking incidents in Alberta, Canada. This study will focus on adults and children over the age of 2 years.
