ArticleData in brief2026
Respiratory and oxygen saturation data for improved modelling and detection of obstructive sleep apnoea.
Article in Data in brief, 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
Twenty healthy adults (10 male, 10 female) participated in a data collection trial designed to capture arterial and venous pulsatile waveforms for oxygen saturation estimation, along with respiratory pressure and flow data to support modelling and prediction of obstructive sleep apnoea (OSA) events. Each participant completed eight one-minute tests while wearing a full-face mask connected to a custom inline pressure and flow sensor, with a Fisher & Paykel SleepStyle CPAP device setting postive PEEP levels at 0, 4, and 8 cmH₂O. A custom reflectance pulse oximeter was taped to the right side of the neck to capture pulsatile waveforms from the carotid artery and internal jugular vein, while a commercial BTIMOS sat801+ pulse oximeter recorded arterial oxygen saturation (SpaO₂) and heart rate from the right index finger. Test conditions included baseline breathing and simulated apnoeas involving 10- and 20-second breath-holds at each PEEP level. Ethical approval was granted by the University of Canterbury Human Research Ethics Committee (Ref: HREC 2024/163/LR-PS). This data aims to support improved apnoea detection, enabling better adaptive control of positive airway pressure (PAP) therapy based on oxygen saturation and respiratory signals.
