A respiration rate (RR) monitoring system was created by integrating a Fibre Bragg Grating (FBG) optical fibre sensor into a respirator mask. The system exploits the sensitivity of an FBG to temperature to identify an individual’s RR by measuring air...

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...

Forehead monitoring of heart rate in neonatal intensive care (2023)
Journal Article
Stockwell, S. J., Kwok, T. C., Morgan, S. P., Sharkey, D., & Hayes-Gill, B. R. (2023). Forehead monitoring of heart rate in neonatal intensive care. Frontiers in Physiology, 14, Article 1127419. https://doi.org/10.3389/fphys.2023.1127419

Heart rate is an extremely important physiological parameter to measure in critically unwell infants, as it is the main physiological marker that changes in response to a change in infant condition. Heart rate is routinely measured peripherally on a... Read More about Forehead monitoring of heart rate in neonatal intensive care.

U-shape functionalized optical fibre sensors for measurement of anaesthetic propofol (2022)
Journal Article
