What this trial studies

This study aims to assess the effectiveness of various choking relief techniques, including abdominal thrusts and two airway clearance devices, LifeVac© and Dechoker©, among laypersons. Participants will watch instructional videos on each technique and then practice them on a simulation mannequin to relieve airway obstructions. The study will measure which intervention achieves the highest success rate in relieving choking within one minute. Participants will return after 90-120 days to evaluate their retention of the techniques.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 years or older who can communicate in English.

Not a fit: Patients with physical disabilities that limit their ability to perform the interventions or those with healthcare training may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could identify the most effective choking intervention for laypersons, potentially saving lives during choking emergencies.

How similar studies have performed: Previous studies have shown varying results for similar interventions, but this study focuses specifically on laypersons, making it a novel approach.
