Comparison of foreign body airway obstruction interventions among laypersons: A simulation-based, crossover, randomized controlled trial.

ABSTRACT:

Background

 Foreign body airway obstruction (FBAO) is a life-threatening emergency where rapid bystander intervention is essential. Suction-based airway clearance devices like Dechoker (DC) and LifeVac (LV) are marketed alternatives to abdominal thrusts (AT), but their efficacy among laypersons is unclear. We aimed to determine which intervention (AT, DC or LV) has the greatest efficacy for FBAO relief by laypersons.

Methods

We conducted a simulation-based, crossover, randomized controlled trial. Adult laypersons received standardized in-person instruction on AT, DC, and LV, then responded to three simulated FBAO events on an adult mannequin. A mixed-effects logistic regression model estimated the odds ratios (OR) of FBAO relief at one minute (primary outcome) and four minut
