Comparative efficacy of LifeVac® and Heimlich maneuver in simulated airway obstruction.
Article in Jornal de pediatria. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesForeign body airway obstruction is a significant cause of morbidity and mortality, especially in infants and young children. This study aims to compare the efficacy of the Heimlich maneuver and LifeVac® in a simulated environment.
methodsA prospective experimental study was conducted using the Choking Charlie (Laerdal®) mannequin, which simulates the trunk from an adult male and is considered suitable for simulating choking events in young children. The study involved four operators: one Pediatric Advanced Life Support (PALS) instructor and professor of Trauma and Emergency Medicine, along with three members of the university's Pediatric Academic League, all previously trained in Basic Life Support (BLS). The primary outcome was the success rate of foreign body removal. Intracavitary pressures generated during the maneuvers were measured using a digital manometer.
resultsA total of 200 anti-choking maneuvers were performed, and both techniques successfully relieved airway obstruction in all cases. The LifeVac® device generated significantly lower intracavitary pressure differentials compared to the Heimlich maneuver (p < 0.000). Additionally, both techniques exhibited significant variability in applied pressure among different examiners (p < 0.000).
conclusionsBoth the Heimlich maneuver and LifeVac® are effective in relieving foreign body airway obstruction when performed by specialists in a simulated environment. Heimlich generated higher positive pressure gradients, while LifeVac® produced lower negative pressure gradients.
