About this study
WHY IS THIS STUDY BEING DONE? Little is known about the best treatment for choking. New airway clearance devices like LifeVac© and Dechoker© are being sold to help a choking person. Researchers do not know how well they work compared to other techniques like abdominal thrusts or back blows.
The purpose of this research study is to see how well bystanders can use the choking techniques.

RESEARCH QUESTION Among laypersons, which FBAO intervention (abdominal thrusts, LifeVac©, or Dechoker©) results in the greatest proportion of FBAO relief within one-minute?
PARTICIPANTS Adults aged 18 years or greater.
INTERVENTIONS View a video of each choking intervention, and then complete a choking scenario where participants will try to relieve an airway obstruction on a simulation mannequin. The three interventions are: LifeVac, Dechoker, and Abdominal Thrusts. Participants will be invited back between 90-120 days to repeat the scenarios to assess retention.
Read the detailed description
Foreign body airway obstructions (FBAO, choking) result in significant mortality and morbidity globally . If left untreated, individuals suffering from airway obstructions will progress to unresponsiveness and die. For the first time in decades, a novel choking intervention is being promoted. Airway clearance devices (such as LifeVac© or Dechoker©) are non-powered suction-based devices being marketed by manufacturers as a safer, easier alternative to traditional choking interventions. However, a systematic review, conducted by Dunne et al, demonstrated insufficient evidence to recommend their use in choking guidelines. Subsequently, a mannequin simulation trial by Patterson found LifeVac© to be superior to abdominal thrusts at FBAO relief within 4 minutes (odds ratio [OR] 47.32 [95%CI 5.74 - 389.40]), whereas Dechoker© was not (OR 1.22 [95% CI 0.60 - 2.47]). This study was only conducted in healthcare professionals, and the efficacy in laypersons is still unknown.
Study Objectives 1. To evaluate the relative efficacy of airway clearance devices compared to traditional interventions among laypersons.
Research Questions and Hypotheses
- Among laypersons, which FBAO intervention (abdominal thrusts, LifeVac©, or Dechoker©) results in the greatest proportion of FBAO relief within one-minutes?
Hypothesis: LifeVac© will relieve more FBAOs within one-minute compared to abdominal thrusts and Dechoker© based on a prior mannequin study among healthcare professionals.
Methods Investigators will conduct an open-label, crossover, mannequin, randomized controlled trial to compare two ACDs (LifeVac© and Dechoker©) with traditional abdominal thrusts as FBAO interventions.
Randomization: Using OnCore randomization service to 1 of 6 intervention orders. Randomization will be performed by a researcher not involved with participant recruitment, and allocation will be concealed until enrollment using OnCore software as well.
Pre-simulation: Prior to any intervention, each participant will receive an orientation to the simulator (Choking Charlie, Laerdal Medical AS, Stavanger, Norway), environment, and the outcomes being assessed. A member of the research team will be available to answer any questions that they have prior to starting.
Intervention: Participants will be shown the manufacturer's (LifeVac© and Dechoker©) recommended short educational video for each intervention. A publicly available online instructional video, prepared by St John Ambulance, will be used for abdominal thrusts. Immediately after watching the first training video in their allocated sequence, participants will be asked to respond to a FBAO scenario, using the assigned technique. Participants will have up to four minutes to complete the intervention. All intervention attempts will be video recorded from a standardized position. Each participant will repeat the process (instructional video, followed by scenario) two more times so that they attempt each intervention. Participants will have a short break (of approximately two minutes) between each intervention.
Follow Up: All participants will be invited back between 90 - 120 days to complete the same scenario with the 3 interventions again to assess skills retention.

Questions about this trial
What is this clinical trial studying?
A study testing Dechoker, LifeVac and Abdominal Thrusts in people with Choking and Airway Obstruction, run by University of Calgary at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Odds Ratio of Airway Obstruction Relief Within One-Minute (time frame: 1 minute). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06227234, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Apr 2026.
