This dataset contains airway gauge pressure, inspiratory differential pressure, and pulse oximetry waveforms collected from 20 healthy adult participants (10 females, 10 males) during simulated obstructive sleep apnoea (OSA) trials. Recordings include photoplethysmography (PPG) signals from a custom neck-worn reflectance oximeter, which records both arterial and venous blood waveforms from the carotid artery and internal jugular vein, respectively. Each subject completed a a series of 8 × 60-second breathing trials with varying positive airway pressures (0, 4, and 8 cmH₂O) set with a continuous positive airway pressure (CPAP) device. Normal breathing was recorded initially before subsequent trials of three breaths followed by 10- and 20-second breath holds, before normal breathing for the rest of the 60 seconds. The dataset is structured to support algorithm development and validation for OSA detection, modelling of airway resistance and oxygen desaturation responses, and non-invasive estimation of arterial and venous oxygen saturation. Supplementary code and figures are included to facilitate data analysis.
