Exploring the Bias: How Skin Colour Influences Oxygen Saturation Readings via Monte Carlo Simulations (2024)
Journal Article
Swamy, S., Liu, C., Correia, R., Hayes-Gill, B., & Morgan, S. (in press). Exploring the Bias: How Skin Colour Influences Oxygen Saturation Readings via Monte Carlo Simulations. Journal of Biomedical Optics,

Significance: Understanding the root cause of reported oxygen saturation (SpO2) overestimation in heavily pigmented skin types to devise solutions toward enabling equity in pulse oximeter design. Aim: To gain theoretical insights into the effect o... Read More about Exploring the Bias: How Skin Colour Influences Oxygen Saturation Readings via Monte Carlo Simulations.

Fabrication and assessment of a bio-inspired synthetic tracheal tissue model for tracheal tube cuff leakage testing (2024)
Journal Article
Agbiki, T., Arm, R., Hewson, D. W., Erdody, S., Norris, A. M., Correia, R., …Morgan, S. P. (2024). Fabrication and assessment of a bio-inspired synthetic tracheal tissue model for tracheal tube cuff leakage testing. BJA Open, 10, Article 100290. https://doi.org/10.1016/j.bjao.2024.100290

Introduction Leakage of orogastric secretions past the cuff of a tracheal tube is a contributory factor in ventilator-associated pneumonia. Current bench test methods specified in the International Standard for Anaesthetic and Respiratory Equipment...

Pulse oximeter bench tests under different simulated skin tones (2024)
Journal Article
Swamy, S. K. N., He, C., Hayes‑Gill, B. R., Hayes-Gill, B. R., Clark, D. J., Green, S., & Morgan, S. P. (2024). Pulse oximeter bench tests under different simulated skin tones. Medical and Biological Engineering and Computing, https://doi.org/10.1007/s11517-024-03091-2

Pulse oximeters’ (POs) varying performance based on skin tones has been highly publicised. Compared to arterial blood gas analysis, POs tend to overestimate oxygen saturation (SpO2) values for people with darker skin (occult hypoxemia). The objective...
