Defining the Efficiency of Manual Ventilation: A Comprehensive Systematic Review.
Article in Emergency medicine international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Manual ventilation is an essential skill for healthcare professionals, especially in emergency and resuscitation situations where mechanical ventilation may not be immediately available. However, improper manual ventilation can lead to serious complications such as barotrauma (lung injury caused by excessive pressure), hypoventilation (leading to insufficient oxygenation), hyperventilation (which can cause respiratory alkalosis and reduced cerebral blood flow), and gastric insufflation (which increases the risk of aspiration). This review aimed to analyze the definitions and methods used to assess manual ventilation efficiency in recent studies. A systematic database search was conducted for the period between 2014 and 2023. The primary inclusion criterion was the assessment of manual ventilation quality in adults. Out of 47 identified studies, eight met the inclusion criteria in the review. Most of the reviewed studies focused on key ventilation parameters including tidal volume and ventilation rate, which are critical for ensuring adequate ventilation. However, we found considerable variability in how "effective ventilation" was defined. This review highlights the approach that considers both extrinsic and intrinsic factors as a potentially more comprehensive method for assessing manual ventilation quality. This approach may offer a more consistent and effective framework for ensuring safe and efficient manual ventilation practices.
