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...

Highly sensitive optical fibre Bragg grating contact pressure sensor embedded in a polymer layer: modelling and experimental validation (2024)
Journal Article
Abeywardena, C., Zhang, Q., Korposh, S., Morgan, S., Bull, S., & Correia, R. (2024). Highly sensitive optical fibre Bragg grating contact pressure sensor embedded in a polymer layer: modelling and experimental validation. Results in Optics, 14, Article 100604. https://doi.org/10.1016/j.rio.2024.100604

This paper discusses mathematical modelling and experimental validation of a highly sensitive optical fibre Bragg grating (FBG) contact pressure sensor developed for healthcare applications. Bare FBGs are not very sensitive to pressure (~ 3x10-3 nm/M...
