Breath-by-breath lung gas volume detection using GASMAS in a neonatal mannequin.
Article in Pediatric research, 2026. 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
Monitoring lung gas volumes of ventilated infants is important. Gas in Scattering Media Absorption Spectroscopy (GASMAS) can estimate gas volume inside tissues by measuring oxygen absorption. We hypothesized that GASMAS can detect different tidal volumes (TV) delivered to mechanically ventilated lungs in a neonatal mannequin model breath-by-breath.
methodsA neonatal mannequin was ventilated with a set range of TVs (2-6 ml), different inspired fractional oxygen (FiO

conclusionGASMAS detects the difference between inspiration, expiration, and tidal volume gas changes, suggesting a potential clinical application of GASMAS for respiratory monitoring of ventilated neonates. IMPACT: What is the key message of your article? An experimental study demonstrating the feasibility of the GASMAS technique for detecting changes in lung gas volume. What does it add to the existing literature? GASMAS detects the difference between inspiratory and expiratory breath phases, various tidal volumes, oxygen concentration, and respiratory rate. What is the impact? This suggests a potential clinical application of GASMAS for respiratory monitoring of neonates.
